Altered resting-state connectivity of the auditory cortex in congenital amusia: A functional magnetic resonance imaging study in Mandarin speakers.

Brain imaging studies have reported that the neural deficits of congenital amusia in non-tonal language speakers are mainly in the connectivity between the auditory cortex and the inferior frontal gyrus (IFG) in the right hemisphere. However, the relationship between the functional connectivity (FC) in these regions and the music perception ability of amusia in tonal language speakers remains unclear. In this study, we investigated the FC characteristics of amusia in Mandarin speakers in resting-state functional magnetic resonance imaging data by voxel-wise connectivity analyses with seeds in left and right Heschl's gyri (HG) and region of interest (ROI)-to-ROI connectivity analyses. Our findings indicate increased connectivity between right HG and bilateral posterior superior temporal gyrus, as determined by voxel-wise connectivity analyses in amusia. Conversely, reduced connectivity was observed between bilateral HG and bilateral IFG (orbital part) as assessed through ROI-to-ROI connectivity analyses in amusia when compared to controls. Moreover, the music perception scores of amusia in Mandarin speakers were associated with diminished connectivity between the left HG and the right IFG. This study furnishes direct evidence for the link between music perception deficits and the aberrant frontotemporal connectivity of congenital amusia in tonal language speakers in resting state.

The perception of emotional prosody in Mandarin Chinese words and sentences

Emotional prosody refers to the ways in which the tone of voice can be modulated to convey emotions, feelings, and attitudes. Previous studies have explored the perception of emotional prosody and whether native speakers (L1) have an in-group advantage in recognizing the emotional prosody of their own cultural groups over non-native speakers. However, little is known about whether these findings in non-tonal languages can be generalized to tonal languages. Mandarin Chinese uses the tone of voice to encode word meanings in addition to emotional prosody. This study investigates the perception of emotional prosody in Mandarin Chinese using an emotion judgment task, focusing on the effects of emotion type (e.g., neutral, joy, anger, sadness) and syllable length (e.g., monosyllable, disyllable, trisyllable, and sentence). Three groups were included, consisting of 20 native Chinese speakers (native group), 20 L1-English L2-Chinese learners (second language group), and 20 native English speakers without Chinese learning experience (non-native group). The results revealed that all three groups can identify emotional prosody well above the chance level in Mandarin Chinese words and sentences. Moreover, the native group and the second language (L2) group showed an in-group advantage in recognizing emotional prosody compared to the non-native group, highlighting the impact of linguistic experience in addition to cultural backgrounds on the perception of emotional prosody. Notably, the effects of emotion type and syllable length differed across the three groups in terms of their perception of emotional prosody. The native group had difficulty identifying positive emotional prosody, whereas both the L2 group and the non-native group showed a pattern of improved accuracy as syllable length increased, with an interaction effect with emotion type.

Effect of Age and Gender on Categorical Perception of Vocal Emotion Under Tonal Language Background.

Categorical perception (CP) manifests in various aspects of human cognition. While there is mounting evidence for CP in facial emotions, CP in vocal emotions remains understudied. The current study attempted to test whether individuals with a tonal language background perceive vocal emotions categorically and to examine how factors such as gender and age influence the plasticity of these perceptual categories. This study examined the identification and discrimination performance of 24 Mandarin-speaking children (14 boys and 10 girls) and 32 adults (16 males and 16 females) when they were presented with three vocal emotion continua. Speech stimuli in each continuum consisted of 11 resynthesized Mandarin disyllabic words. CP phenomena were detected when Mandarin participants perceived vocal emotions. We further found the modulating effect of age and gender in vocal emotion categorization. Our results demonstrate for the first time that a categorical strategy is used by Mandarin speakers when perceiving vocal emotions. Furthermore, our findings reveal that the categorization ability of vocal emotions follows a prolonged course of development and the maturation patterns differ across genders. This study opens a promising line of research for investigating how sensory features are mapped to higher order perception and provides implications for our understanding of clinical populations characterized by altered emotional processing. https://doi.org/10.23641/asha.27204057.

Assessing journalists’ language tone and sources used in reporting HIV/AIDS information in Tanzanian newspapers

Assessing journalists’ language tone and sources used in reporting HIV/AIDS information in Tanzanian newspapers

A cross-linguistic review of citation tone production studies: Methodology and recommendations.

The study of citation tones, lexical tones produced in isolation, is one of the first steps towards understanding speech prosody in tone languages. However, methodologies for investigating citation tones vary significantly, often leading to limited comparability of tone inventories, both within and across languages. This paper presents a systematic review of research methods and practices in 136 citation tone studies on 129 tonal language varieties in China, including 99 studies published in Chinese, which are therefore not easily available to an international scientific readership. The review provides an overview of possible analytical decisions along the research pipeline, and unveils considerable variation in data collection, analysis, and reporting conventions, particularly in how f0, the primary acoustic correlate for tone, is operationalised and reported across studies. Key methodological issues are identified, including small sample sizes and inadequate transparency in communicating methodological decisions and procedure. This paper offers a clear road map for citation tone production research and proposes a range of recommendations on speaker sampling, experimental design, acoustic processing techniques, f0 analysis, and result reporting, with the goal of facilitating future tonal research and enhancing resources for underrepresented tonal varieties.

Cross-Linguistic Nasalance Comparisons: A Review of Speech Sample Sets and Preliminary Consideration of Effect of Lexical Tone.

Nasalance is an acoustic representation of perceived nasality with proven clinical and research utility. Its validity is contingent on appropriate speech sample sets and distinct normative databases based on known impact factors such as language and phonetic environment, but little is known about the potential effects of lexical tone on nasalance. Its use in international cross-linguistic studies necessitates definition and added considerations of speech sampling protocol. Part I. A methodological review was undertaken using PRISMA (2020), the Scottish Intercollegiate Guidelines Network (SIGN) Methodology Checklist for evaluating risk of bias, and calculation of effect sizes and/or visual displays using tables showing grouping of similar data for synthesis of findings. Part II. A pilot study explored the effect of lexical tone on nasalance in Cantonese, a lexical tone language. Part I. 17 studies met the inclusion criteria. In addressing possible confounders and minimizing risk of bias, 13 studies were assigned an overall quality rating of (+) acceptable and the remaining 4, a high rating (++). For the 9-word string, there was a (non-clinical) difference of 3-5% between Swedish and Brazilian-Portuguese, and a moderate effect size for age (d=0.49); for the consonant-vowel syllables set (CV set), clinical differences across languages were identified for adults, and between 5-10% for children and adolescents. Part II. The pilot study showed a significant effect of lexical tone on nasalance where nasalance for the high-level tone 1 was significantly higher than that for high-rising tone 2, low-rising tone 5, and low-falling tone 4. There is a need for further evidence from other languages, including tonal languages, to better define the evidence and speech methodology of international cross-linguistic nasalance studies.

A - 147 Patient-Centric Considerations for Selecting the Language of Procedure Administration in Candidates for Epilepsy Surgery: Implications for Data Interpretation, Prognostication and Outcomes

Abstract Objective Selecting the language of pre-surgical neuropsychological testing (NPT), intracarotid amobarbital procedure, and intra/extra functional language mapping (ESM) in bi−/multi-lingual patients is a high-stakes neuropsychological decision point. Though a patient’s self-selection of language is an integral consideration, both patient and provider must fully understand the potential implications of language selection on a patient’s data interpretation and overall case conceptualization. Method A 26-year-old, right-handed, bilingual (L1 = Mandarin-, L2 = English-speaking) female received pre-operative NPT, Wada test, and ESM to guide resective surgery targeting medically-refractory epilepsy involving the right superior temporal gyrus (STG) and mesial (MTL) temporal lobe. All procedures were conducted in English at the patient’s request with alternate forms of verbally-mediated NPT administered in Mandarin. Results Confrontation naming and verbal fluencies were impaired in both English and Mandarin. Wada testing administered in English revealed bilateral language and greater left hemisphere memory support. Following considerable psychoeducation regarding possible functional language loss in Mandarin post-operatively, the patient agreed to ESM in L1 with auditory and picture naming disruption after right STG stimulation. Conclusion Despite strong English-language fluency, assessment in Mandarin was of critical importance, as eloquent cortices essential for tonal language production may have been resected if mapping procedures were completed in English-only, as requested. Balancing factors informed by functional and structural neuroanatomy, patient worldview, and cross-cultural neuropsychology requires a tailored, patient-centric approach to case conceptualization.

Native language background affects the perception of duration and pitch

Estonian is a quantity language with both a primary duration cue and a secondary pitch cue, whereas Chinese is a tonal language with a dominant pitch use. Using a mismatch negativity experiment and a behavioral discrimination experiment, we investigated how native language background affects the perception of duration only, pitch only, and duration plus pitch information. Chinese participants perceived duration in Estonian as meaningless acoustic information due to a lack of phonological use of duration in their native language; however, they demonstrated a better pitch discrimination ability than Estonian participants. On the other hand, Estonian participants outperformed Chinese participants in perceiving the non-speech pure tones that resembled the Estonian quantity (i.e., containing both duration and pitch information). Our results indicate that native language background affects the perception of duration and pitch and that such an effect is not specific to processing speech sounds.

Musician Advantage for Segregation of Competing Speech in Native Tonal Language Speakers

The aim of this study was to replicate previous English-language musician advantage studies in Mandarin-speaking musicians and nonmusicians. Segregation of competing speech, melodic pitch perception, and spectro-temporal pattern perception were measured in normal-hearing native Mandarin-speaking musicians and nonmusicians. Speech recognition thresholds were measured in the presence of two-talker masker speech. The masker sex was either the same as or different from the target; target and masker speech were either co-located or spatially separated. Melodic pitch perception was tested using a melodic contour identification task. Spectro-temporal resolution was measured using a modified spectral ripple detection task. We hypothesized that, given musician advantages in pitch perception, musician effects would be larger when the target and masker sex was the same than when different. For all tests, performance was significantly better for musicians than for nonmusicians. Contrary to our expectation, larger musician effects were observed for segregation of competing speech when the target and masker sex was different. The results show that musician effects observed for non-tonal language speakers extend to tonal language speakers. The data also suggest that musician effects may depend on the difficulty of the listening task and may be reduced when listening tasks are too easy or too difficult.

Acoustic patterns in Hong Kong Cantonese hesitation markers: Vowel quality and omnisyllabic tone

ABSTRACT: Hesitation markers (HMs) lie somewhere on the dividing line between linguistic and sub-linguistic, evincing at the same time crosslinguistic commonalities as well as language-specific features (Candea et al. 2005; Dingemanse and Woensdregt 2020). This study seeks to expand on understanding of these lexically peripheral items by analyzing their acoustic properties in Hong Kong Cantonese (HKCT), including vowel quality and F0. Recent work by Dingemanse and Woensdregt (2020) discusses phonetic similarities in HMs across languages, which are constrained by adherence to the phonologies of their respective languages. However, it is unclear how HMs are incorporated into HKCT tonal phonology, which can be characterized as 'omnisyllabic' (Matisoff 1995), every syllable being associated with a lexical tone. The present study gathers acoustic data (F0, F1–F2, duration) from the PolyU Corpus of Spoken Chinese (http://wongtaksum.no-ip.info:81/corpus.htm) across 10 speakers and 196 HMs, comparing them against 525 lexical items. Results for F1–F2 clustered around mid-front /ɛ/, which is in line both with crosslinguistic trends and HKCT phonology. Results for F0 clustered around the lower end of the pitch range, approaching Tones 3 and 6, which is expected given effort minimization trends. However, establishing a connection with a particular lexical tone was complicated by the similarity of Tones 3 and 6, which could not be statistically distinguished. Cross-speaker analysis showed considerable variation in F0, indicating that context, intonation, or idiolectal variation may play a substantial role. This has implications for our understanding of how peripheral items like hesitation markers are treated in omnisyllabic tone languages like Cantonese. 摘要: 犹豫标记置身语言学与副语言学的边界，占据一个既有跨语言共性又 具特定语言特征的区域(Candea et al. 2005; Dingemanse and Woensdregt 2020)。本研究旨在透过分析犹豫标记在香港粤语中，包含元音音色 及 F0 的声学特性，扩充对这些语义周边项目的理解。Dingemanse and Woensdregt(2020)最近的研究论及犹豫标记有跨语言声学相似性，亦 受制于各语言对自身的音段音韵学的持守。不过，香港粤语作为"全 音节语言"(Matisoff 1995)，每个音节均附上声调，犹豫标记应如何 纳入香港粤语的声调音韵学，这仍不清楚。本研究从理工大学中文口 语语料库 (PolyU Corpus of Spoken Chinese, http://wongtaksum.noip.info:81/corpus.htm) 集结 F0、 F1–F2 及时长的声学资料，横跨十位语 者，共 196 个犹豫标记，与 525 个词汇作比较分析。F1–F2 的结果围 绕半开前元音/ɛ/丛集，与跨语言趋势及香港粤语音韵学均能匹配。F0 的结果则丛集于近乎最低的音高，接近调三及调六，合乎最少付出倾 向的预想。可是，要与特定字词声调建立联系仍很复杂，因为调三及 调六相似，不能以统计学区分。跨语者分析显示 F0 有相当变化，提示 语境、语调或个人习语变化可能有重大影响。这对理解全音节语言 (如粤语)如何应对犹豫标记等等周边项目有所提示。

The prediction of segmental and tonal information in Mandarin Chinese: an eye-tracking investigation

ABSTRACT There is controversy about the extent to which people predict phonology during comprehension. In three visual-world experiments, we ask whether it occurs in Mandarin, a tonal language. Participants heard sentences containing a target word that was highly predictable (Cloze 80.2%, Experiment 1) or very highly predictable (Cloze 93.9%, Experiments 2–3) and saw an array of objects containing one whose name matched the target word (Experiments 1–2), was unrelated to the target word (Experiments 1–3), or matched the target word in segment and tone (Experiments 1–3), in segment only (Experiments 1–3), or tone only (Experiment 3). In comparison to the unrelated object, participants looked more at the segment + tone object (Experiments 1–3), and sometimes at the segment object (Experiments 1 and 3), but not at the tone object. We conclude that participants predict segmental information independently of tone.

The Roles of Segments and Tone in Mandarin Lexical Processing: An ERP Study.

Segments and tone are important sub-syllabic units that play large roles in lexical processing in tonal languages. However, their roles in lexical processing remain unclear, and the event-related potential (ERP) technique will benefit the exploration of the cognitive mechanism in lexical processing. The high temporal resolution of ERP enables the technique to interpret rapidly changing spoken language performances. The present ERP study examined the different roles of segments and tone in Mandarin Chinese lexical processing. An auditory priming experiment was designed that included five types of priming stimuli: consonant mismatch, vowel mismatch, tone mismatch, unrelated mismatch, and identity. Participants were asked to judge whether the target of the prime-target pair was a real Mandarin disyllabic word or not. Behavioral results including reaction time and response accuracy and ERP results were collected. Results were different from those of previous studies that showed the dominant role of consonants in lexical access in mainly non-tonal languages like English. Our results showed that consonants and vowels play comparable roles, whereas tone plays a less important role than do consonants and vowels in lexical processing in Mandarin. These results have implications for understanding the brain mechanisms in lexical processing of tonal languages.

Voice actors show enhanced neural tracking of pitch, prosody perception, and music perception

Experiences with sound that make strong demands on the precision of perception, such as musical training and experience speaking a tone language, can enhance auditory neural encoding. Are high demands on the precision of perception necessary for training to drive auditory neural plasticity? Voice actors are an ideal subject population for answering this question. Voice acting requires exaggerating prosodic cues to convey emotion, character, and linguistic structure, drawing upon attention to sound, memory for sound features, and accurate sound production, but not fine perceptual precision. Here we assessed neural encoding of pitch using the frequency-following response (FFR), as well as prosody, music, and sound perception, in voice actors and a matched group of non-actors. We find that the consistency of neural sound encoding, prosody perception, and musical phrase perception are all enhanced in voice actors, suggesting that a range of neural and behavioural auditory processing enhancements can result from training which lacks fine perceptual precision. However, fine discrimination was not enhanced in voice actors but was linked to degree of musical experience, suggesting that low-level auditory processing can only be enhanced by demanding perceptual training. These findings suggest that training which taxes attention, memory, and production but is not perceptually taxing may be a way to boost neural encoding of sound and auditory pattern detection in individuals with poor auditory skills.

The breath shape controls intonation of mouse vocalizations.

Intonation in speech is the control of vocal pitch to layer expressive meaning to communication, like increasing pitch to indicate a question. Also, stereotyped patterns of pitch are used to create distinct sounds with different denotations, like in tonal languages and, perhaps, the 10 sounds in the murine lexicon. A basic tone is created by exhalation through a constricted laryngeal voice box, and it is thought that more complex utterances are produced solely by dynamic changes in laryngeal tension. But perhaps, the shifting pitch also results from altering the swiftness of exhalation. Consistent with the latter model, we describe that intonation in most vocalization types follows deviations in exhalation that appear to be generated by the re-activation of the cardinal breathing muscle for inspiration. We also show that the brainstem vocalization central pattern generator, the iRO, can create this breath pattern. Consequently, ectopic activation of the iRO not only induces phonation, but also the pitch patterns that compose most of the vocalizations in the murine lexicon. These results reveal a novel brainstem mechanism for intonation.

The process of vowel harmony in Kurdish language in the framework of Autosegmental phonology

This study discusses the vowels harmony in Kurdish language. Vowel harmony like assimilation process is a very common process in most languages of the world. This process is studied by most phonological theories, such as generative phonology, autosegmental phonology as well as optimality theory. We examine this process from the perspective of autosegmental phonology in this paper. Therefore, we can say that the aim of this study is to investigate the process of vowel harmony in Kurdish language from the perspective of autosegmental phonology. The methodology of this study is to analyze the content of the articles and collect the data with appropriate samples. Autosegmental theory is one of the theories in the field of phonology and was first emerged by Goldsmith as an independent field of generative phonology. In 1976, along with the study of rhyme languages, he introduced autosegmental phonology and then it was published in tonal languages. This theory is actually a field or part of production phonology.

Speech Perception and Quality-of-Life Outcomes in Mandarin-Speaking Postlingual Deaf Adults With Cochlear Implant: Any Difference With the Intonation Language Users?

To evaluate the effects of related factors on long-term speech perception and quality-of-life (QoL) outcomes in postlingual deaf Mandarin-speaking adult cochlear implant (CI) recipients and to assess any differences between tone language and other intonation language CI adult users. Retrospective cases review. Tertiary referral center. Forty-five adult CI recipients (48 implanted ears). Post-CI outcomes were evaluated after follow-ups of more than 24 months using speech perception tests and QoL questionnaires. We analyzed the related factors affecting CI outcomes. A shorter duration of profound deafness was predictive factors for better post-CI speech perception. Earlier implantation and better performance of vowel scores were predictive of better subjective improvements in social and emotional life. Post-CI vowel scores of over 56% indicated promising improvements in QoL. Shorter duration of deafness could have better post-CI speech perception. Post-CI vowel scores instead of monosyllable words have the more potential to predict the QoL in Mandarin-speaking adult CI recipients.

Prosodic Weight Effect on Focal Accent of Standard Chinese

This study investigates the phonetic performance of narrow information focus, as compared to broad focus, within different sentential positions of the Chinese Subject-Verb-Object (S+V+O) syntax structure. Three acoustic parameters of focus, including the pitch range ratio, duration ratio, and intensity ratio, were taken to explore the ranking among these parameters and to analyse the impact of focus position on their interrelationships. The results showed that (1) Chinese, as a tonal language, exhibits a prosodic ranking characterized by duration > pitch range > intensity; (2) Chinese speakers tend to emphasize verbs within the S+V+O syntax structure, particularly when verbs are positioned in the middle of sentences. The prosodic ranking observed was Fmiddle > Finitial > Ffinal; (3) Pitch range and duration display interdependence as acoustic parameters, whereas intensity stands as an independent parameter. These results contribute to a deeper understanding of phonetic nuances within Chinese prosody, shedding light on the intricate interplay between focus, syntax, and prosody.

Enhancing tonal‐language learning through music: A review of experimental methods and melodic intonation therapy influences

AbstractThis literature review explores the impact of music on tonal language learning, with a focus on Mandarin Chinese. Utilising searches across major databases such as ERIC (EBSCO), ProQuest Central, Google Scholar, and Web of Science from 2005 to 2024, we selected relevant peer‐reviewed English‐language articles examining music's role in aiding tone acquisition and related cognitive processes. From 30 publications, findings are categorised into theoretical relationships, cognitive effects, melodic intonation therapy (MIT) applications and digital music applications. Theoretical frameworks emphasise the correlation between musicality and language proficiency, highlighting musicians' enhanced tonal perception and production skills. Cognitive effects include music's influence on pronunciation, memory and cultural understanding. MIT's effectiveness in tonal language learning is then discussed, emphasising its potential to improve cortical representations of tone categories. Finally, digital music applications are examined, focusing on language learning apps incorporating music for personalised and engaging learning experiences. The review finds significant literature reporting that music‐based methodologies, aligned with experiential learning paradigms, hold significant potential in Mandarin Chinese acquisition. They enhance listening comprehension, spoken language production, and understanding of grammar and syntax. Similar to MIT principles, music‐assisted tonal language learning utilises exaggerated melody and rhythm to improve language production, especially with complex words. This review is motivated by the recognition of music's potential benefits in language education, especially for tonal languages. It aims to provide educators and researchers with insights into effective methods and applications, guiding instructional practices and stimulating further empirical investigations in this interdisciplinary field. Ultimately, it contributes to the ongoing discourse on optimising tonal language learning methodologies.

Rates of change and phylogenetic signal in Mixtec tone

Abstract Despite the abundance of tonal languages around the world, the diachrony of tone is still poorly understood, especially when compared to segmental sound change. This lacuna has contributed to the untested assumption that tones are inherently unstable and change unpredictably. This paper addresses the questions of whether tones change faster than segments and whether tones show less phylogenetic signal than segments in the Mixtec languages of southern Mexico. To this end, I created a database of tonal and segmental sound changes across a sample of 42 Mixtec languages. I calculated phylogenetic signal with the metric D and estimated rates of change with a hidden Markov model across a posterior sample of phylogenetic trees. The results show that the majority of tone changes show phylogenetic signal and that they generally do not change at a faster rate than segments.

Distributional Learning and Overnight Consolidation of Nonnative Tonal Contrasts by Tonal Language Speakers.

Previous studies have reported the success of distributional learning for adult speakers across segmental and suprasegmental categories immediately after training. On the other hand, second language (L2) perception models posit that the ease with which learners perceive a nonnative speech contrast depends on the perceptual mapping between the contrast and learners' first language (L1) categories. This study examined whether a difference in perceptual mapping patterns for different L2-Mandarin tonal contrasts might result in a difference in distributional learning effectiveness for tonal speakers and whether an interval of sleep enhanced the knowledge through consolidation. Following a pretest-training-posttest design, 66 L1-Cantonese participants with fewer than 9 years of Mandarin training were assigned to either the bimodal or unimodal distribution conditions. The participants of each group were asked to discriminate Mandarin level-falling (T1-T4) and level-rising (T1-T2) tone pairs on novel syllables in a within-subject design. All participants were trained in the evening, tested after training, and returned after 12 hr for overnight consolidation assessment. A significant distributional learning effect was observed for Mandarin T1-T4, but only after sleep. No significant distributional learning effect was observed for Mandarin T1-T2, either after training or after sleep. The findings may imply that distributional learning is contingent on perceptual mapping patterns of the target contrasts and that sleep may play a role in the consolidation of knowledge in an implicit statistical learning paradigm. https://doi.org/10.23641/asha.25970008.
