Connected Speech Fluency in Poststroke and Progressive Aphasia: A Scoping Review of Quantitative Approaches and Features.

Speech fluency has important diagnostic implications for individuals with poststroke aphasia (PSA) as well as primary progressive aphasia (PPA), and quantitative assessment of connected speech has emerged as a widely used approach across both etiologies. The purpose of this review was to provide a clearer picture on the range, nature, and utility of individual quantitative speech/language measures and methods used to assess connected speech fluency in PSA and PPA, and to compare approaches across etiologies. We conducted a scoping review of literature published between 2012 and 2022 following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews guidelines. Forty-five studies were included in the review. Literature was charted and summarized by etiology and characteristics of included patient populations and method(s) used for derivation and analysis of speech/language features. For a subset of included articles, we also charted the individual quantitative speech/language features reported and the level of significance of reported results. Results showed that similar methodological approaches have been used to quantify connected speech fluency in both PSA and PPA. Two hundred nine individual speech-language features were analyzed in total, with low levels of convergence across etiology on specific features but greater agreement on the most salient features. The most useful features for differentiating fluent from nonfluent aphasia in both PSA and PPA were features related to overall speech quantity, speech rate, or grammatical competence. Data from this review demonstrate the feasibility and utility of quantitative approaches to index connected speech fluency in PSA and PPA. We identified emergent trends toward automated analysis methods and data-driven approaches, which offer promising avenues for clinical translation of quantitative approaches. There is a further need for improved consensus on which subset of individual features might be most clinically useful for assessment and monitoring of fluency. https://doi.org/10.23641/asha.25537237.

Surgical Management of Airway Obstruction Following Posterior Pharyngeal Flap.

Posterior pharyngeal flap (PPF) is effective in managing velopharyngeal insufficiency (VPI) but is of airway obstruction risk. This study compared the effectiveness and complications of two PPF revision procedures and screened potential prognostic factors to postoperative hypernasality and persistent obstruction. Patients who received flap division (FD) or port enlargement (PE) for airway obstruction following PPF were reviewed. Ventilation status was assessed using the nasal obstruction symptom evaluation (NOSE) scale, and velopharyngeal closure was assessed using subjective speech evaluation and nasopharyngoscopy. The effectiveness of ventilation relief and complication rate (hypernasality and persistent obstruction) of the two techniques were compared. A comprehensive panel of factors, including age, velopharyngeal mobility, obstruction laterality, body mass index, jaw relationship, and adenoid hypertrophy, were evaluated for correlation with complications. 79 patients were enrolled, with 51 receiving FD and 28 PE. Both techniques significantly improved ventilation dysfunction and hyponasality. Mild hypernasality occurred among 10 cases in the FD group and 3 in the PE group. Age at surgery was significantly associated with persistent obstruction after PPF revision. The occurrence of persistent obstruction was significantly higher among patients below 12 years than those above. Obstruction laterality was suggested in significant correlation with hypernasality post-PPF revision. Among patients with unilateral port obstruction, the occurrence of hypernasality after FD was significantly higher than after PE. Both flap division and port enlargement are effective revision procedures to relieve airway obstruction after PPF. Patients below 12 years are more likely to experience persistent ventilation problem after PPF revision.

Analysis Of Emotions Through Speech Recognition

Speech emotion recognition (SER) is a burgeoning field in AI that analyzes vocal characteristics to understand human emotions. It delves deeper than the literal meaning of words, uncovering emotional cues hidden within speech patterns. Pitch, loudness, and speech rate are just a few features that vary with emotional state. SER utilizes machine learning algorithms to classify these features into categories like happiness, sadness, or anger. This technology offers a treasure trove of possibilities, from enhancing human-computer interaction to revolutionizing customer service and even aiding in mental health assessments. As SER continues to evolve, it holds the potential to transform how we connect with machines, fostering deeper understanding and richer emotional experiences.

Effectiveness of secondary furlow palatoplasty with buccal myomucosal flap in correction of velopharyngeal insufficiency in patients with cleft palate

ObjectivesThe main purpose of this study was evaluation of the effectiveness of secondary furlow palatoplasty with buccal myomucosal flap (FPBF) for the treatment of velopharyngeal insufficiency (VPI) in patients with a cleft palate who were treated with two flap palatoplasty (TFP) in their primary palate repair.Material and methodsTwenty-three medically free children aged 4–8 years with non-syndromic and previously repaired cleft palate via TFP participated in the study. All patients received secondary surgery following the technique of FPBF. Preoperative speech evaluation was done before the secondary repair and 3 months after the surgery using a hypernasal speech scale, speech intelligibility scale, and nasopharyngoscopy.ResultsA statistically significant improvement was observed regarding the degree of hypernasality and speech intelligibility while comparing the preoperative scores after the primary surgery to the postoperative scores after the secondary surgery.In addition, a statistically significant improvement was found in the nasopharyngoscopic assessment.ConclusionsThe incorporation of a buccal myomucosal flap with Furlow palatoplasty was successful in improving hypernasality, speech intelligibility, and nasopharyngoscopic scores in patients with cleft palate.Trial registrationclinicaltrials.gov (NCT05626933).Clinical relevanceThis technique might be the surgical technique of choice while treating patients who are suffering from VPI after cleft palate repair.

The relationships between language, functional hearing, social, and motor development skills in children with early cochlear implants

PurposeThe purpose of this study was to investigate the relations between functional hearing, language, social, bilateral coordination and manual dexterity skills in children with early cochlear implants (CIs).MethodsThirty children with CIs were included in this study. The manual dexterity and bilateral coordination development of the participants were evaluated with Manual Dexterity and Bilateral Coordination subtests of Bruininks-Oseretsky Motor Proficiency-2 (BOT-2). Their language skills were assessed by the Test of Early language Development-3. To assess the functional hearing of participants the Functioning After Pediatric Cochlear Implantation scale (FAPCI) was administered their caregivers. Also, the Social Skills Evaluation Scale was administered to participants’ teachers to asses their social skills.ResultsThere were significant correlations between participants’ receptive and expressive language skills, Manual Dexterity, and FAPCI scores (p < 0.05). There were also significant relationships between the SSES and FAPCI scores of the participants (p < 0.05). However, the Bilateral Coordination subtest did not show any significant correlation with any of the measurements (p > 0.05).ConclusionThe results suggest that the language, manual dexterity and functional hearing abilities of children with CIs are closely related. Although, there were no significant correlations between all of the measurement, it is important to look beyond hearing and speech evaluations to assess the whole child.

Universal and Language-Specific Connected Speech Characteristics of Bilingual Speakers With Alzheimer's Disease: Insights From Case Studies of Structurally Distinct Languages.

Connected speech analysis has been effectively utilized for the diagnosis and disease monitoring of individuals with Alzheimer's disease (AD). Existing research has been conducted mostly in monolingual English speakers with a noticeable lack of evidence from bilinguals and non-English speakers, particularly in non-European languages. Using a case study approach, we characterized connected speech profiles of two Bengali-English bilingual speakers with AD to determine the universal features of language impairments in both languages, identify language-specific differences between the languages, and explore language impairment characteristics of the participants with AD in relation to their bilingual language experience. Participants included two Bengali-English bilingual speakers with AD and a group of age-, gender-, education-, and language-matched neurologically healthy controls. Connected speech samples were collected in first language (L1; Bengali) and second language (L2; English) using a novel storytelling task (i.e., Frog, Where Are You?). These samples were analyzed using an augmented quantitative production analysis and correct information unit analyses for productivity, fluency, syntactic and morphosyntactic features, and lexical and semantic characteristics. Irrespective of the language, AD impacted speech productivity (speech rate and fluency) and semantic characteristics in both languages. Unique language-specific differences were noted on syntactic measures (reduced sentence length in Bengali), lexical distribution (fewer pronouns and absence of reduplication in Bengali), and inflectional properties (no difficulties with noun or verb inflections in Bengali). Among the two participants with AD, the individual who showed lower proficiency and usage in L2 (English) demonstrated reduced syntactic complexity and morphosyntactic richness in English. Evidence from these case studies suggests that language impairment features in AD are not universal across languages, particularly in comparison to impairments typically associated with language breakdowns in English. This study underscores the importance of establishing connected speech profiles in AD for non-English-speaking populations, especially for structurally different languages. This would in turn lead to the development of language-specific markers that can facilitate early detection of language deterioration and aid in improving diagnosis of AD in individuals belonging to underserved linguistically diverse populations. https://doi.org/10.23641/asha.25412458.

Superiorly Based Posterior Pharyngeal Flaps: Using A Care Pathway to Optimize Speech and Airway Outcomes.

Pharyngeal flap (PF) surgery is effective at improving velopharyngeal sufficiency, but historical literature shows a concerning prevalence rate of obstructive sleep apnea (OSA), reported as high as 20%. Our institution has developed a protocol to minimize risk of postoperative obstructive complications and increase safety of PF surgery. We hypothesize that (1) preoperative staged removal of significant adenotonsillar tissue along with (2) multiview videofluoroscopy to guide patient-specific surgical approach via appropriately sized PFs can result in excellent speech outcomes while limiting occurrence of OSA. This was a retrospective chart review of all patients with velopharyngeal insufficiency (VPI) (aged 2-20 years) seen at the University of Rochester from 2015 to 2022 undergoing PF surgery to correct VPI. Nasopharyngoscopy was used for surgical planning and airway evaluation. Patients with tonsillar and adenoid hypertrophy underwent staged adenotonsillectomy at least 2 months before PF. Multiview videofluoroscopy was used to identify anatomic causes of VPI and to determine PF width. Patients underwent polysomnography and speech evaluation before and at least 6 months after PF surgery. Forty-one children aged 8.5 ± 4.1 years (range, 4 to 18 years) who underwent posterior PF surgery for VPI were identified. This included 10 patients with 22q11.2 deletion and 4 patients with Pierre Robin sequence. Thirty-nine patients had both pre- and postoperative speech data and underwent both a pre- and postoperative sleep study. Polysomnography showed no significant difference in obstructive apnea-hypopnea index after posterior PF surgery (obstructive apnea-hypopnea index preop, 1.3 ± 1.2 events per hour; postop, 1.7 ± 2.1 events per hour; P = 0.111). Significant improvements in speech outcome were seen in patients who underwent PF (modified Pittsburgh score preop, 11.52 ± 1.37; postop, 1.09 ± 2.35; P < 0.05). Use of preoperative staged adenotonsillectomy as well as patient-specific PF dimensions results in effective resolution of VPI and a low risk of OSA.

Linking Digital Traits from Facial Expression, Voice, and Head Motion to Montgomery–Åsberg Depression Rating Scale Subscales

IntroductionThe 10-item Montgomery–Åsberg Depression Rating Scale (MADRS) measures different dimensions of depression symptomatology. Digital traits may generate deeper understanding of the MADRS subscales and provide insights about depression symptomatology.ObjectivesTo identify digital traits that predict specific MADRS subscales and ascertain which digital traits are important for which MADRS subscales.Methods During a Phase II decentralised clinical trial in major depressive disorder (MDD), patients completed the MADRS and used AiCure (LLC, New York, NY, USA), a smartphone application, to complete image description tasks at baseline. Digital measurements identified from the literature as relevant to MDD symptomatology were conducted using audio and video data derived from the image description tasks. Digital measurements included speech (rate, sentiment and first-person singular pronouns), vocal acoustics (intensity, pause fraction and fundamental frequency), facial expressivity (regional facial movement) and head pose (Euclidean and angular head movement). Digital traits analysis involved data pre-processing followed by machine learning (ML) using Elastic Net, Decision Tree, and Random Forest models; model performance was evaluated using 5-fold cross-validation and mean absolute error (MAE). Important digital traits were calculated by percentage change in MAE after permuting a specific variable. Important digital traits for the MADRS Apparent Sadness subscale score were mapped to defined, interpretable domains.ResultsThe ML model predictions varied for different MADRS subscales (Table). Overall, Elastic Net and Random Forest models outperformed Decision Tree across all subscales scores other than suicidal thoughts. Half of the literature-based digital traits contributed to the prediction of ≥1 MADRS sadness sub-scale score. The important digital traits for the Apparent Sadness subscale score could be mapped to 4 domains (Figure); this aligned with findings from the literature.Image:Image 2:ConclusionsDigital traits collected from patients with MDD were able to predict certain MADRS subscales better than others.FundingBoehringer Ingelheim.Disclosure of InterestZ.

Defining Trajectories of Linguistic, Cognitive-Communicative, and Quality of Life Outcomes in Aphasia: Longitudinal Observational Study Protocol

ObjectiveTo describe the trajectories of linguistic, cognitive-communicative, and health-related quality of life (HRQOL) outcomes after stroke in persons with aphasia. DesignLongitudinal observational study from inpatient rehabilitation to 18 months after stroke. SettingFour US mid-west inpatient rehabilitation facilities (IRFs). ParticipantsWe plan to recruit 400 adult (older than 21 years) English speakers who meet the following inclusion criteria: (1) Diagnosis of aphasia after a left-hemisphere infarct confirmed by CT scan or magnetic resonance imaging (MRI); (2) first admission for inpatient rehabilitation due to a neurologic event; and (3) sufficient cognitive capacity to provide informed consent and participate in testing. Exclusion criteria include any neurologic condition other than stroke that could affect language, cognition or speech, such as Parkinson's disease, Alzheimer's disease, traumatic brain injury, or the presence of right-hemisphere lesions. InterventionsNot applicable. Main Outcome MeasuresSubjects are administered a test battery of linguistic, cognitive-communicative, and HRQOL measures. Linguistic measures include the Western Aphasia Battery-Revised and the Apraxia of Speech Rating Scale. Cognitive-communicative measures include the Communication Participation Item Bank, Connor's Continuous Performance Test-3, the Communication Confidence Rating Scale for Aphasia, the Communication Effectiveness Index, the Neurological Quality of Life measurement system (Neuro-QoL) Communication short form, and the Neuro-QoL Cognitive Function short form. HRQOL measures include the 39-item Stroke & Aphasia Quality of Life Scale, Neuro-QoL Fatigue, Sleep Disturbance, Depression, Ability to Participate in Social Roles & Activities, and Satisfaction with Social Roles & Activities tests, and the Patient-Reported Outcome Measurement and Information System 10-item Global Health short form. The test battery is administered initially during inpatient rehabilitation, and at 3-, 6-, 12-, and 18-months post-IRF discharge. Biomarker samples are collected via saliva samples at admission and a subgroup of participants also undergo resting state fMRI scans. ResultsNot applicable. ConclusionsThis longitudinal observational study will develop trajectory models for recovery of clinically relevant linguistic, cognitive-communicative, and quality of life outcomes over 18 months after inpatient rehabilitation. Models will identify individual differences in the patterns of recovery based on variations in personal, genetic, imaging, and therapy characteristics. The resulting models will provide an unparalleled representation of recovery from aphasia resulting from stroke. This improved understanding of recovery will enable clinicians to better tailor and plan rehabilitation therapies to individual patient's needs.

Speech Outcomes After Palatal Lengthening Via Double Opposing Buccinator Myomucosal Flaps.

Palatal lengthening is becoming a first-line treatment choice for cleft patients with velopharyngeal insufficiency (VPI). As cleft palate-related surgical outcomes are age dependent, speech outcomes may be similarly affected by patient age at the time of treatment. The primary goal of this study is to determine whether there are age-related speech outcome differences when double opposing buccinator myomucosal flaps are used as part of a palatal lengthening protocol and whether these outcome differences preclude utilization of this technique for specific patient age groups. A retrospective study was performed on consecutive nonsyndromic patients with VPI who underwent treatment using double opposing buccinator myomucosal flaps at our hospital between 2014 and 2021. Patients who completed the 15-month follow-up were stratified by age. Group A aged between 2 and 7 years (n = 14), group B aged 8 and 18 years (n = 23), and group C aged older than 18 years (n = 25) were included. Standardized perceptual speech evaluations and nasopharyngoscopy were performed. Hypernasality, soft palate mobility, and lateral palatal wall mobility were assessed both preoperatively and at a 15-month postoperative interval. Complications were also recorded. The χ2 test was used for statistical comparison. All of the age-stratified patient groups in this study showed significant improvement in hypernasality, soft palate mobility, and lateral wall mobility (P < 0.01), with no statistically significant differences between the different patient age groups. Overall speech success was achieved in 69.4% of patients. Patients in group A achieved 78.6% speech success, patients in group B achieved 78.3% speech success, and patients in group C achieved 56% speech success, with no statistically significant differences being shown regarding speech success between the different patient age groups (P > 0.05). Regardless of age, palatal lengthening via double opposing buccinator myomucosal flaps similarly improves speech outcomes.

한국 영어 듣기학습자를 위한 다양한 영어 실제(authentic) 자료 보통속도 연구

Objectives Normal English speed is a core factor of characteristics of authentic spoken language; thus, its study is essential for teaching English listening. The purpose of this study is two fold: 1) To investigate English normal speed(160~190 wpm), which was claimed by Primsleur, et. al. 45 years ago; and 2) To find out whether normal speed is utilized in teaching of listening in Korean high schools.&#x0D; Methods To find out current normal English speed, we investigated 42 YouTube materials from varied genres. In addition, a survey was conducted with 22 prospective English teachers.&#x0D; Results The research findings on the speech rate for various genres are: speeches (135 wpm), dramas (141 wpm), talk shows (174 wpm), and news (185 wpm). We found out that the normal speed has been maintained for 45 years under similar conditions as measured by the news announcers' speeches. The survey reveals that slower than normal speed is utilized in English listening classes, which makes Korean learners of English experience difficulties in authentic situations.&#x0D; Conclusions Utilizing the normal speed is recommended on the Korean Scholastic Ability Test listening items and in the English classroom alike, to solve the speed gap between the English classroom in Korea and authentic situations in English.&#x0D;

영어 부정극어 발화유형 비교

This study investigated the speech acts of Korean adolescents, focusing on the English negative polarity item(NPI) ‘any’, which, unlike Korean, exhibits subject-object asymmetry. Specifically, differences in speech rates of NPIs and indefinite pronouns were confirmed in the subject and object positions. English NPIs mainly appear in negative contexts and conditional sentences, and since they must comply with the C-command conditions, indefinite pronouns mainly appear in the subject position, and relatively both NPIs and indefinite pronouns appear in the object position. Focusing on these basic theories, this study checked what they were like in practice. Overall, the rate of utterance of indefinite pronouns in the subject position was much higher than that of NPIs. And the fact that the rate of utterance of indefinite pronouns increases with age may be a result of learning. In the object position, the rate of utterance of indefinite pronouns was found to be similar and slightly higher than that of NPIs. This means that participants may know through learning or innately that both NPIs and indefinite pronouns are possible in the object position. It was found that the younger Korean adolescents were, the more familiar they were with the use of NPIs with the negative word ‘not’, and the less familiar they were with the use of indefinite pronouns with negative connotation. This is believed to be proportional to the frequency of appearance of ‘not’, which is commonly used in negative sentences in a second language environment.

Pediatric normative data for a novel and fast speech perception test in noise

ObjectivesCommunicating in noisy settings can be difficult due to interference and environmental noise, which can impact intelligibility for those with hearing impairments and those with normal hearing threshold. Speech intelligibility is commonly assessed in audiology through speech audiometry in quiet environments. Nevertheless, this test may not effectively assess hearing challenges in noisy environments, as total silence is rare in daily activities. A recently patented method, known as the SRT50 FAST, has been developed for conducting speech audiometry in noise. This new method enables the acceleration and simplification of free field speech audiometry tests involving competition noise.This study aims to establish normative scores and standardize the SRT50 FAST method as a test for evaluating speech perception in noise in pediatric patients. MethodsThe study included 30 participants with normal hearing, consisting of 11 females and 19 males, ranging in age from 6 to 11 years. A series of speech audiometry tests were conducted to determine the speech reception threshold 50% (SRT50) in competing conditions. This included testing both the fast mode (SRT50 FAST) currently being studied and the traditional method (SRT50 CLASSIC). The SRT50, or Signal to Noise Ratio (SNR) at which 50% of speech recognition occurred, was investigated for both methods. ResultsThe mean SRT50 FAST test score was −2.69 (SD = 3.15). The dataset exhibited a normal distribution with values ranging from 3.60 to −8.60. Since the scores are expressed in SRT, higher scores indicate poorer performance. We have established a threshold of 3.60 as the upper limit of the normal range, therefore, patients with scores above this threshold are considered to have abnormal results. ConclusionsThis study aimed to establish normative data for the evaluation of free field speech in noise recognition using the SRT50 FAST method in the pediatric population. This method accurately investigates the necessary signal-to-noise ratio for achieving 50% recognition scores with bisyllabic words in a quick manner. The ultimate objective is to employ this test to identify the optimal configuration of hearing rehabilitation devices, particularly for pediatric patients with hearing aids and/or cochlear implants. Additionally, it can be used to assess pediatric patients with unilateral hearing loss.

Stability Over Time of Word Syllable Duration for Speakers With Acquired Apraxia of Speech.

Neurogenic speech and language disorders-such as acquired apraxia of speech (AOS) and aphasia with phonemic paraphasia (APP)-are often misdiagnosed due to similarities in clinical presentation. Word syllable duration (WSD)-a measure of average syllable length in multisyllabic words-serves as a proxy for speech rate, which is an important and arguably more objective clinical characteristic of AOS and APP. This study reports stability of WSD over time for speakers with AOS (and aphasia). Twenty-nine participants with AOS and aphasia (11 women and 18 men, Mage = 53.5 years, SD = 13.3) repeated 30 multisyllabic words (of three-, four-, and five-syllable lengths) on three occasions across 4 weeks. WSDs were calculated for each word and then averaged across each list (i.e., word length), as well as across combined lists (i.e., all 30 words) to yield four WSDs for each participant at each time point. Stability over time was calculated using Friedman's test for the group and using Spearman's rho for the individual level. Effects of time and word length were examined using robust mixed-effects linear regression. Friedman's tests and correlations indicated no significant difference in WSDs across sampling occasions for each word length separately or combined. WSD correlated positively with AOS severity and negatively with intelligibility but was not correlated with aphasia severity. Regression analyses confirmed WSD to be stable over time, while WSD calculated from only five tokens (i.e., WSD-5) was less stable over time. Results indicate that WSD can be a stable measure over time, at the individual and group level, providing support for its use in diagnosis and/or as an outcome measure, both clinically and for research. In general, WSD outperformed WSD-5, suggesting that it may be better to calculate WSD from more than five tokens. Stability of WSD in other populations and suitability for differential diagnosis need to be determined. Currently, differentiating disorders by speaking rate, alone, is not recommended. https://doi.org/10.23641/asha.25438735.

Constructional sources of durational shortening in discourse markers

Abstract Using naturally occurring data from Spanish from Madrid, this study is the first to analyze durations of the Spanish word decir ‘to say, to tell’ both as a verb with prepositional meaning and as part of the reformulating construction [es decir] ‘that is to say’ (N = 388). We show that, although it is neither highly grammaticalized nor frequent, [es decir] undergoes phonological reduction to a significantly greater degree than the more frequent lexical source decir ‘to say’. Results of linear mixed-effects models predicting target duration suggest these durational differences cannot be explained due to conditioning factors of the target context controlled in this analysis (speech rate of the target word context, predictability of following words, number of phones, distance from pause). They do not appear to stem from an accumulation in memory of patterns of likelihood of use in those conditioning environments. We propose that [es decir] is stored as a lexical unit that contains as part of the lexical representation shorter word durations relative to the lexical form decir and that this durational shortening is part of the [reformulator] construction.

Clinical Focus: The Development and Description of a Palette of Transmasculine Voices.

The study of gender and speech has historically excluded studies of transmasculine individuals. Consequently, generalizations about speech and gender are based on cisgender individuals. This lack of representation hinders clinical training and clinical service delivery, particularly by speech-language pathologists providing gender-affirming communication services. This letter describes a new corpus of the speech of American English-speaking transmasculine men, transmasculine nonbinary people, and cisgender men that is open and available to clinicians and researchers. Twenty masculine-presenting native English speakers from the Upper Midwestern United States (including cisgender men, transmasculine men, and transmasculine nonbinary people) were recorded, producing three sets of speech materials: Consensus Auditory-Perceptual Evaluation of Voice sentences, the Rainbow Passage, and a novel set of sentences developed for this project. Acoustic measures vowels (overall formant frequency scaling, vowel-space dispersion, fundamental frequency, breathiness), consonants (voice onset time of word-initial voiceless stops, spectral moments of word-initial /s/), and the entire sentence (rate of speech) that were made. The acoustic measures reveal a wide range for all dependent measures and low correlations among the measures. Results show that many of the voices depart considerably from the norms for men's speech in published studies. This new corpus can be used to illustrate different ways of sounding masculine by speech-language pathologists performing gender-affirming communication services and by higher education teachers as examples of diverse ways of sounding masculine.

(Heritage) Russian Case Marking: Variation and Paths of Change

Russian’s six cases and multiple noun classes make case marking potentially challenging ground for heritage speakers. Indeed, morphological levelling, “probably the best-described feature of language loss”, has been substantiated. One study from 2006 showed that Heritage Russian speakers in the USA produced canonical or prescribed markers for only 13% of preposition+nominal sequences. Conversely, another study from 2020 found that Heritage Russian speakers in Toronto produce a 94% canonical case marker rate in conversational speech. To explore the effects of methodological differences across several studies, the current paper circumscribes the context to preposition+nominal sequences in Heritage Russian speech from the same Toronto corpus as used by the 2020 study but mirroring the domain investigated by Polinsky and including a Homeland comparison to consider changes in both the rates of use of canonical case marking and distributional patterns of non-canonical use. Regression models show more canonical case marking in more frequent words, an independent effect of slightly more mismatch by later generations, but less morphological levelling than reported by Polinsky. Lexicon size does not predict case marking rates as strongly as language usage patterns do, but generation, since immigration, is the best-fitting social predictor. We confirm (small) rate changes in Heritage (vs. Homeland) Russian canonical case marking but not in patterns of levelling.

Combining wav2vec 2.0 Fine-Tuning and ConLearnNet for Speech Emotion Recognition

Speech emotion recognition poses challenges due to the varied expression of emotions through intonation and speech rate. In order to reduce the loss of emotional information during the recognition process and to enhance the extraction and classification of speech emotions and thus improve the ability of speech emotion recognition, we propose a novel approach in two folds. Firstly, a feed-forward network with skip connections (SCFFN) is introduced to fine-tune wav2vec 2.0 and extract emotion embeddings. Subsequently, ConLearnNet is employed for emotion classification. ConLearnNet comprises three steps: feature learning, contrastive learning, and classification. Feature learning transforms the input, while contrastive learning encourages similar representations for samples from the same category and discriminative representations for different categories. Experimental results on the IEMOCAP and the EMO-DB datasets demonstrate the superiority of our proposed method compared to state-of-the-art systems. We achieve a WA and UAR of 72.86% and 72.85% on IEMOCAP, and 97.20% and 96.41% on the EMO-DB, respectively.

A Single Institution 19 Year Comparison of Furlow and Straight Line Palatoplasty Techniques in Bilateral Cleft Lip and Palate.

This study aims to compare patients' speech correcting surgery and fistula rates between the Furlow and Straight Line (SLR) palatoplasty techniques when combined with greater palatine flaps for complete bilateral cleft lip and palate (BCLP) repair. This was a single-center IRB approved retrospective cohort study. This study took place at an urban tertiary academic center. All patients with BCLP anomalies that underwent repair between January 2003 and August 2022 were included. Patients with index operations at an outside institution or incomplete medical charting were excluded. A total of 1552 patients underwent palatoplasty during the study period. Of these, 192 (12.4%) met inclusion criteria with a diagnosis of BCLP. Primary outcomes of this study included rate of fistula and incidence of speech correcting surgery. Secondary outcomes included rate of surgical fistula repair. One hundred patients underwent SLR (52.1%) and 92 Furlow repair (47.9%). There was no significant difference in fistula rates between the SLR and Furlow repair cohorts (20.7% vs. 15.0%; p = 0.403). However, SLR was associated with lower rates of speech correcting surgery when compared to the Furlow repair (12.5% vs. 29.6%; p = 0.011). This study compares the effect of Furlow and SLR on speech outcomes and fistula rates in patients with BCLP. Our findings suggest that SLR resulted in an almost three times lower rate of velopharyngeal dysfunction requiring surgical intervention in patients with BCLP, while fistula rates remained similar.

The Synergistic Effects of Preterm Birth and Parent Gender on the Linguistic and Interactive Features of Parent-Infant Conversations.

To investigate the language environments experienced by preterm-born infants, this study compared the linguistic and interactive features of parent-infant conversations involving 2-year-old preterm- and term-born infants. The study also explored how mother-infant and father-infant conversations may be differentially affected by preterm/term birth status. Twenty-two preterm-born (< 37 weeks' gestation) and 25 term-born (≥ 37 weeks' gestation) 2-year-old infants engaged in dyadic mother/father-infant free-play interactions that were transcribed to quantify the linguistic (parental volubility, speech rate, lexical diversity, and morphosyntactic complexity) and interactive (infant/parent responsiveness, turn-taking, and conversational balance) features of parent-infant conversations. Language, cognitive, socioemotional, and executive function skills were assessed via standardized tools. Compared to the term group, the preterm group was characterized by lower maternal speech rate, parental lexical diversity, and parent-infant turn-taking, as well as greater mother-infant conversational balance. The preterm group presented poorer language and executive function skills when compared to the term group. Both similarities and differences exist between the language environments of preterm and term groups. Similarities may be due to the partial developmental catch-up of preterm-born infants (cognitive and socioemotional skills) and parental scaffolding. Differences may partly reflect a parental adaptation to the language and executive function difficulties of preterm-born infants. These findings suggest that researchers/clinicians should appraise the language environment with respect to the unique developmental needs of preterm/term-born infants. Future research directions are provided to advance a more holistic characterization of the language environment and a deeper understanding of the developmental significance of preterm-term differences in such environments. https://doi.org/10.23641/asha.25021931.
