Facilitation of vocabulary acquisition by emotional prosody in children with autism

Helping children with autism gain a better grasp of vocabulary is an important way to improve their language skills. Information that incorporates emotional prosodies provide richer semantics and context and may be more conducive to vocabulary acquisition in children with autism. This study aimed to explore the facilitating effect of positive emotional prosody on vocabulary acquisition with children with autism. A total of 12 children with autism received interventions with neutral and positive emotional prosodies. The results revealed that vocabulary learned in positive emotional prosodies was more effective than neutral prosodies. The differences in the learning effects of emotional prosodies on part of speech were not significant. However, in children with higher autism severity, neutral prosodies led to diminished expressive vocabulary performance. This study improved vocabulary comprehension and language skills of children with autism through emotional prosody intervention and tentatively revealed the role of lexicality in this.

Vocal and Consonant Patterns in Indonesian Children's Songs

As a medium in educational music, the song provides space for explanations related to the sound of the language. Prosody or language sounds have similarities to musical sounds studied in phonology. Thus, the management of language sounds in expressing children's songs can be used to identify prosodic factors in educational music. This study aims to provide an explanation of the prosody of children's songs in the context of educational music and to find out the factors that influence prosody in children's songs, the sound changes that occur, accompaniment sounds that accompany the main sound, and the factors that influence it in the context of music education. The results of this study show the characteristics of vowel and consonant sounds in children's song lyrics and the sounds produced for certain vowels and consonants. The factors that influence prosody in children's songs are the word order in the form of vowels and consonants in each of the lyrics. This is to clearly understand the sounds produced by children and their use in educational music.

Communicating Emotion: Vocal Expression of Linguistic and Emotional Prosody in Children With Mild to Profound Hearing Loss Compared With That of Normal Hearing Peers.

Emotional prosody is known to play an important role in social communication. Research has shown that children with cochlear implants (CCIs) may face challenges in their ability to express prosody, as their expressions may have less distinct acoustic contrasts and therefore may be judged less accurately. The prosody of children with milder degrees of hearing loss, wearing hearing aids, has sparsely been investigated. More understanding of the prosodic expression by children with hearing loss, hearing aid users in particular, could create more awareness among healthcare professionals and parents on limitations in social communication, which awareness may lead to more targeted rehabilitation. This study aimed to compare the prosodic expression potential of children wearing hearing aids (CHA) with that of CCIs and children with normal hearing (CNH). In this prospective experimental study, utterances of pediatric hearing aid users, cochlear implant users, and CNH containing emotional expressions (happy, sad, and angry) were recorded during a reading task. Of the utterances, three acoustic properties were calculated: fundamental frequency (F0), variance in fundamental frequency (SD of F0), and intensity. Acoustic properties of the utterances were compared within subjects and between groups. A total of 75 children were included (CHA: 26, CCI: 23, and CNH: 26). Participants were between 7 and 13 years of age. The 15 CCI with congenital hearing loss had received the cochlear implant at median age of 8 months. The acoustic patterns of emotions uttered by CHA were similar to those of CCI and CNH. Only in CCI, we found no difference in F0 variation between happiness and anger, although an intensity difference was present. In addition, CCI and CHA produced poorer happy-sad contrasts than did CNH. The findings of this study suggest that on a fundamental, acoustic level, both CHA and CCI have a prosodic expression potential that is almost on par with normal hearing peers. However, there were some minor limitations observed in the prosodic expression of these children, it is important to determine whether these differences are perceptible to listeners and could affect social communication. This study sets the groundwork for more research that will help us fully understand the implications of these findings and how they may affect the communication abilities of these children. With a clearer understanding of these factors, we can develop effective ways to help improve their communication skills.

Reduced Neural Specialization for Word-level Linguistic Prosody in Children with Autism.

Children with autism often show atypical brain lateralization for speech and language processing, however, it is unclear what linguistic component contributes to this phenomenon. Here we measured event-related potential (ERP) responses in 21 school-age autistic children and 25 age-matched neurotypical (NT) peers during listening to word-level prosodic stimuli. We found that both groups displayed larger late negative response (LNR) amplitude to native prosody than to nonnative prosody; however, unlike the NT group exhibiting left-lateralized LNR distinction of prosodic phonology, the autism group showed no evidence of LNR lateralization. Moreover, in both groups, the LNR effects were only present for prosodic phonology but not for phoneme-free prosodic acoustics. These results extended the findings of inadequate neural specialization for language in autism to sub-lexical prosodic structures.

Perception of prosody in children with auditory processing disorders

ABSTRACT The objective of this study was to investigate perception of affective prosody in a group of children diagnosed as having auditory processing disorders (APDs) and compare their performance with those of typically developing children. Auditory Linguistic Integration test in Marathi, which assesses affective prosody, was administered on 159 children in the age range of 5–7 years. Among them, 53 children had APD, and 106 children did not have APD. The results of the study revealed that the perception of affective prosody was significantly poor in children with APD when compared to typically developing children. The results of the study suggested that a subset of children with APD may show difficulty in the perception of affective prosody. Further studies need to be carried out to explore the factors that can affect the perception of affective prosody in children with APD.

On the role of voice and prosody in argumentation among pre-school children

This paper focuses on the role of voice and prosody in children’s argumentation and its relation to framing argumentation as more or less cooperative. Theoretically the project draws from rhetoric, argumentation studies, child studies and linguistics. After a brief overview of the current state in children’s argumentation we shall discuss the notion of multimodality in argumentation studies, specifically the role of voice and prosody in argumentation. The paper analyses two instances of child–child argumentation that show striking similarities and differences: Both deal with the same quaestio – that is the same controversial standpoint – and employ similar topoi – that is formal and material resources for arguments. However, they differ with respect to the cooperative framing – that relates in part to the framing of the interaction as fictional or factual – and with respect to the interaction tension. Methodologically, the paper takes a sequential perspective, grounded in conversation analysis and auditory phonetics. We work with longitudinal corpora of authentic child–child communication (3.0–7.0) in play. We argue that other-than-verbal means like voice and prosody play a crucial role in framing the interaction, thereby mediating the degree of cooperativity. This mediation has consequences for the elaboration of argumentative sequences by the children. Thus, voice and prosody we argue, can play a substantial role in argumentation.

Perception of vocal emotional prosody in children with hearing impairment

PurposeThe study aimed at testing the effect of supra segmental training on vocal emotional prosody perception of children with hearing impairment. The objectives of the study were to compare the perception of vocal emotional prosody (happy, sad, and neutral) in children with hearing impairment with and without a short-term prosody training and to draw correlations between the vocal emotional prosody perception scores and the subject factors - chronological age, age of hearing aid fitting, duration of the intensive intervention (speech, language and auditory training without breaks more than 30 days) and language age in children with hearing impairment. MethodThirty children with hearing impairment in the age range of 4.1–9.2 years with a language age of 3–7 years participated in the study. The authors formulated 24 concrete Malayalam sentences and their picture representations and these were recorded under three emotional variations (happy, sad, and neutral). Using random sampling, the thirty participants were divided into the control group (CWHI) and the experimental (CWHIt) group. The study was carried out in two phases; phase 1 (training) attended by only the experimental group and phase 2 (testing) attended by both the groups. ResultsThere was a significant difference between CWHI and CWHIt in the happy, sad, and neutral vocal emotional prosody conditions. Chronological age, duration of speech-language-auditory training, and language age showed a positive correlation with the vocal emotional prosody perception scores; and no correlation was found between the age of fitting of hearing aids and the emotion perception scores. ConclusionThe results of the study points out that with adequate prosody training, the children with hearing impairment using benefiting hearing aids could improve their vocal emotional prosody perception. Owing to the role of prosody perception in speech & language, social and cognitive development, the supra segmental training should be made an integral part of the assessment and management intervention strategies.

Discourse Prosody in Children's Rhyme Speech Produced by Prelingually Deaf Mandarin-Speaking Children With Cochlear Implants

Purpose This study aimed to obtain a comprehensive understanding about how Mandarin-speaking children with cochlear implants (CIs) performed speech prosody in a connected discourse and to what extent their prosodic scenario differed from those normal-hearing (NH) peers. Method Fifteen prelingually deaf Mandarin-speaking children with unilateral multichannel CIs were chosen and 15 age-matched NH controls were recruited. Speech samples were spontaneously elicited by children's rhyme speech genre and subject to phonetic annotation. Acoustic analysis was conducted on all speech samples, mainly focusing on the measurements of duration and fundamental frequency (F0). Tempo measures included temporal fluency, syllable-lengthening, and rhythm metrics, whereas melodic measures included both local and global F0 variations under different prosodic domains. Results The CI children generally achieved compatible temporal performance with the NH children in spontaneous discourse, except that they were somewhat arbitrary when operationalizing lengthening strategy and pausing strategy at different prosodic boundaries. With regard to melodic performance, CI children may not sufficiently modulate local phonetic nuances of F0 variation, and meanwhile, they performed atypically in the global F0 declination pattern and overall F0 resetting pattern, failing to signal the specific structure of children's rhyme discourse. Early age at implantation and longer CI experience did not play a significant role in the temporal performance of the CI children but did facilitate their articulation of dynamic pitch variation in the spontaneous discourse to some extent. Conclusion CI children did exhibit atypical prosodic patterns in discourse context, especially the overall mapping between the prosodic manifestation and the discourse structure.

따라말하기 과제를 통한 자폐범주성 장애 아동과 일반 아동의 평서문과 의문문의 음향학적 특성 비교*

The prosody of children with autism spectrum disorders (ASD) has several abnormal features, including monotonous speech. The purpose of this study was to compare acoustic features between an ASD group and a typically developing (TD) group and within the ASD group. The study also examined audience perceptions of the lengthening effect of increasing the number of syllables. 50 participants were divided into two groups (20 with ASD and 30 TD), and they were asked to imitate a total of 28 sentences. In the auditory-perceptual evaluation, seven participants chose sentence types in 115 sentences. Pitch, intensity, speech rate, and pitch slope were used to analyze the significant differences. In conclusion, the ASD group showed higher pitch and intensity and a lower overall speaking rate than the TD group. Moreover, there were significant differences in s2 slope of interrogative sentences. Finally, based on the auditory-perceptual evaluation, only 4.3% of interrogative sentences produced by participants with ASD were perceived as declarative sentences. The cause of this abnormal prosody has not been clearly identified; however, pragmatic ability and other characteristics of autism are related to ASD prosody. This study identified prosodic ASD patterns and suggested the need to develop treatments to improve prosody.

Lexical stress contrastivity in Italian children with autism spectrum disorders: an exploratory acoustic study.

We investigated production of lexical stress in children with and without autism spectrum disorders (ASD), all monolingual Italian speakers. The mean age of the 16 autistic children was 5.73 years and the mean age of the 16 typically developing children was 4.65 years. Picture-naming targets were five trisyllabic words that began with a weak-strong pattern of lexical stress across the initial two syllables (WS: matita) and five trisyllabic words beginning with a strong-weak pattern (SW: gomito). Acoustic measures of the duration, fundamental frequency, and intensity of the first two vowels for correct word productions were used to calculate a normalised Pairwise Variability Index (PVI) for WS and SW words. Results of acoustic analyses indicated no statistically significant group differences in PVIs. Results should be interpreted in line with the exploratory nature of this study. We hope this study will encourage additional cross-linguistic studies of prosody in children's speech production.

Prosodic control in imitative speech of preschool-age children with cochlear implants

ABSTRACTThis study aimed to (a) to investigate the acoustic characteristics of speech in preschool-age children with cochlear implants (CIs) compared to those in age-matched children with normal hearing (NH), (b) to identify which acoustic measures could differentiate children with CIs from children with NH, (c) to explore the relationships between child variables and the perceptually judged ability to control prosody in the CI group, and (d) to examine predictors of perceptually judged ability in children with CIs to control prosody. Study participants included 30 children with CIs (3–5.9 years old) and 30 age-matched children with NH. Children were asked to imitate 20 utterances, which were syntactically matched 10 statements and 10 questions. Fundamental frequency, intensity, and duration measures were obtained from the final word of each utterance. Ten adults rated the prosodic-contour appropriateness of the children with CIs using a 5-point scale. Children with CIs tended to produce less distinctive declarative and interrogative utterances compared to children with NH. The mean F0 significantly differentiated children with CIs from their NH peers. In children with CIs, perceptual ratings of prosodic-contour appropriateness were significantly correlated with age, duration of implant use, and percentage of consonants corrects. Duration of implant use was a significant factor predicting the ability to control prosody in children with CIs. These findings suggested that preschool-age children with CIs have difficulty in controlling pitch parameters, compared with the NH peers. The prosodic development in children with CIs was affected by the hearing experience via CIs.

Recognition of Facial Emotion and Affective Prosody in Children at High Risk of Criminal Behavior.

Emotion recognition is an important aspect of emotion processing, which is needed for appropriate social behavior and normal socialization. Previous studies in adults with antisocial personality disorder or psychopathy, in those convicted of criminal behavior, or in children with conduct disorder show impairments in negative emotion recognition. The present study investigated affective facial and prosody recognition in a sample of children at high risk of developing future criminal behavior. Participants were 8- to 12-year-old children at high risk of developing criminal behavior (N=219, 83.1% boys) and typically developing controls (N=43, 72.1% boys). The high-risk children were recruited through an ongoing early intervention project of the city of Amsterdam, that focuses on the underage siblings or children of delinquents, and those failing to attend school. Facial and vocal recognition of happy, sad, angry, and fear was measured with the Facial Emotion Recognition (FER) test and the prosody test of the Amsterdam Neuropsychological Tasks (ANT), respectively. The high-risk group was significantly worse in facial affect recognition and had particular problems with fear and sadness recognition. No hostile attribution bias was found. The high-risk group did not differ from controls in affective prosody recognition but needed significantly more time to recognize emotions. The emotion-specific deficits found in forensic and clinical populations are already present in a sample of children at high risk of developing future criminal behavior. These findings help us understand a possible underlying mechanism of antisocial behavior that could provide directions for tailored interventions. (JINS, 2019, 25, 57-64).

Children’s use of prosody and word order to indicate information status in English noun phrase conjuncts

Our study investigates the influence of information status on word order and prosody in children and adults. Using an elicited production task, we examine the ordering and intonation of noun phrases in phrasal conjuncts in 3-5-year-old and adult speakers of English. Findings show that English-speaking children are less likely to employ the ‘old-before-new’ order than adults and are also not adult-like in using prosody to mark information status. Our study suggests that even though intonation and word order are linguistic devices that are acquired early, their use to mark information status is still developing at age four.

Bono Bo and Fla Mingo: Reflections of Speech Prosody in German Second Graders' Writing to Dictation.

Written German is characterized by an underrepresentation of prosody. During writing acquisition, children have to tackle the question which prosodic features are realized by what means – if any. We examined traces of speech prosody in German children’s writing to dictation. A sample of 79 second graders were asked to write down eight sentences to dictation. We analyzed three potential reflections of speech prosody in children’s dictations: (a) Merging of preposition and definite article, potentially preferred after monosyllabic prepositions as in this case preposition and article may melt to the canonical trochaic foot in German. (b) The introduction of orthographically inadequate graphemic border markings within trisyllabic animal names, respecting borders of prosodic units like foot or syllable. (c) Omissions of the definite article in non-optimal prosodic positions, deviating from the preferred strong-weak rhythm. The occurrence of border markings was evaluated via graded perceptual judgments. We found no evidence for inter-word border markings being influenced by prosodic context, probably due to a ceiling effect. However, word-internal markings within animal names, although rarely occurring in general, were clearly influenced by prosodic structure: Most of them were produced at borders of feet or syllables, while significantly fewer markings were perceived at borders of syllable constituents or within consonant clusters. Moreover, we observed significantly more omissions of the definite article in non-optimal prosodic positions compared to potentially optimal positions. Thus, our results provide first evidence from writing acquisition for prosodic influences on writing in a language with scarce graphemic marking of prosody.

Impaired neural discrimination of emotional speech prosody in children with autism spectrum disorder and language impairment

Autism spectrum disorders (ASD) are characterized by deficient social and communication skills, including difficulties in perceiving speech prosody. The present study addressed processing of emotional prosodic changes (sad, scornful and commanding) in natural word stimuli in typically developed school-aged children and in children with ASD and language impairment. We found that the responses to a repetitive word were diminished in amplitude in the children with ASD, reflecting impaired speech encoding. Furthermore, the amplitude of the MMN/LDN component, reflecting cortical discrimination of sound changes, was diminished in the children with ASD for the scornful deviant. In addition, the amplitude of the P3a, reflecting involuntary orienting to attention-catching changes, was diminished in the children with ASD for the scornful deviant and tended to be smaller for the sad deviant. These results suggest that prosody processing in ASD is impaired at various levels of neural processing, including deficient pre-attentive discrimination and involuntary orientation to speech prosody.

English-speaking preschoolers can use phrasal prosody for syntactic parsing.

This study tested American preschoolers' ability to use phrasal prosody to constrain their syntactic analysis of locally ambiguous sentences containing noun/verb homophones (e.g., [The baby flies] [hide in the shadows] vs [The baby] [flies his kite], brackets indicate prosodic boundaries). The words following the homophone were masked, such that prosodic cues were the only disambiguating information. In an oral completion task, 4- to 5-year-olds successfully exploited the sentence's prosodic structure to assign the appropriate syntactic category to the target word, mirroring previous results in French (but challenging previous English-language results) and providing cross-linguistic evidence for the role of phrasal prosody in children's syntactic analysis.

The Interface of Syntax with Pragmatics and Prosody in Children with Autism Spectrum Disorders.

In order to study problems of individuals with Autism Spectrum Disorders (ASD) with morphosyntax, we investigated twenty high-functioning Greek-speaking children (mean age: 6;11) and twenty age- and language-matched typically developing children on environments that allow or forbid object clitics or their corresponding noun phrase. Children with ASD fell behind typically developing children in comprehending and producing simple clitics and producing noun phrases in focus structures. The two groups performed similarly in comprehending and producing clitics in clitic left dislocation and in producing noun phrases in non-focus structures. We argue that children with ASD have difficulties at the interface of (morpho)syntax with pragmatics and prosody, namely, distinguishing a discourse prominent element, and considering intonation relevant for a particular interpretation that excludes clitics.
