Production and perception of emotional prosody by adults with autism spectrum disorder / Daniel J. HUBBARD in Autism Research, 10-12 (December 2017)  

Public ISBD [article]  inAutism Research > 10-12 (December 2017) . - p.1991-2001 Titre : Production and perception of emotional prosody by adults with autism spectrum disorder Type de document : Texte imprimé et/ou numérique Auteurs : Daniel J. HUBBARD, Auteur ; Daniel J. FASO, Auteur ; Peter F. ASSMANN, Auteur ; Noah J. SASSON, Auteur Article en page(s) : p.1991-2001 Langues : Anglais (eng) Mots-clés : Autism spectrum disorder  emotion  affective prosody  expressive speech  vocal affect  speech production  speech perception Index. décimale : PER Périodiques Résumé : This study examined production and perception of affective prosody by adults with autism spectrum disorder (ASD). Previous research has reported increased pitch variability in talkers with ASD compared to typically developing (TD) controls in grammatical speaking tasks (e.g., comparing interrogative vs. declarative sentences), but it is unclear whether this pattern extends to emotional speech. In this study, speech recordings in five emotion contexts (angry, happy, interested, sad, and neutral) were obtained from 15 adult males with ASD and 15 controls (Experiment 1), and were later presented to 52 listeners (22 with ASD) who were asked to identify the emotion expressed and rate the level of naturalness of the emotion in each recording (Experiment 2). Compared to the TD group, talkers with ASD produced phrases with greater intensity, longer durations, and increased pitch range for all emotions except neutral, suggesting that their greater pitch variability was specific to emotional contexts. When asked to identify emotion from speech, both groups of listeners were more accurate at identifying the emotion context from speech produced by ASD speakers compared to TD speakers, but rated ASD emotional speech as sounding less natural. Collectively, these results reveal differences in emotional speech production in talkers with ASD that provide an acoustic basis for reported perceptions of oddness in the speech presentation of adults with ASD.

Lay Summary This study examined emotional speech communication produced and perceived by adults with autism spectrum disorder (ASD) and typically-developing (TD) controls. Compared to the TD group, talkers with ASD produced emotional phrases that were louder, longer, and more variable in pitch. Both ASD and TD listeners were more accurate at identifying emotion in speech produced by ASD speakers compared to TD speakers, but rated ASD emotional speech as sounding less natural.

Speech motor planning and execution deficits in early childhood stuttering / B. WALSH in Journal of Neurodevelopmental Disorders, 7-1 (December 2015)  

Public ISBD [article]  inJournal of Neurodevelopmental Disorders > 7-1 (December 2015) . - p.27 Titre : Speech motor planning and execution deficits in early childhood stuttering Type de document : Texte imprimé et/ou numérique Auteurs : B. WALSH, Auteur ; K. M. METTEL, Auteur ; A. SMITH, Auteur Article en page(s) : p.27 Langues : Anglais (eng) Mots-clés : Preschool children  Sex differences  Speech kinematics  Speech motor control  Speech production  Stuttering Index. décimale : PER Périodiques Résumé : BACKGROUND: Five to eight percent of preschool children develop stuttering, a speech disorder with clearly observable, hallmark symptoms: sound repetitions, prolongations, and blocks. While the speech motor processes underlying stuttering have been widely documented in adults, few studies to date have assessed the speech motor dynamics of stuttering near its onset. We assessed fundamental characteristics of speech movements in preschool children who stutter and their fluent peers to determine if atypical speech motor characteristics described for adults are early features of the disorder or arise later in the development of chronic stuttering. METHODS: Orofacial movement data were recorded from 58 children who stutter and 43 children who do not stutter aged 4;0 to 5;11 (years; months) in a sentence production task. For single speech movements and multiple speech movement sequences, we computed displacement amplitude, velocity, and duration. For the phrase level movement sequence, we computed an index of articulation coordination consistency for repeated productions of the sentence. RESULTS: Boys who stutter, but not girls, produced speech with reduced amplitudes and velocities of articulatory movement. All children produced speech with similar durations. Boys, particularly the boys who stuttered, had more variable patterns of articulatory coordination compared to girls. CONCLUSIONS: This study is the first to demonstrate sex-specific differences in speech motor control processes between preschool boys and girls who are stuttering. The sex-specific lag in speech motor development in many boys who stutter likely has significant implications for the dramatically different recovery rates between male and female preschoolers who stutter. Further, our findings document that atypical speech motor development is an early feature of stuttering.

In this brief report, we present an analysis of vowel productions from 74 American English speakers who participated in a communicative speaking task. Results show higher autistic trait load to be broadly and inversely related to spectral correlates of vowel intelligibility. However, the statistical significance of this relationship is specific to autistic traits along the pragmatic communication dimension, and limited to female speakers.

Exploring the Relationship between Prosodic Control and Social Competence in Children with and without Autism Spectrum Disorder / Nichole E. SCHEERER in Autism Research, 13-11 (November 2020)  

Public ISBD [article]  inAutism Research > 13-11 (November 2020) . - p.1880-1892 Titre : Exploring the Relationship between Prosodic Control and Social Competence in Children with and without Autism Spectrum Disorder Type de document : Texte imprimé et/ou numérique Auteurs : Nichole E. SCHEERER, Auteur ; Jeffery A. JONES, Auteur ; Grace IAROCCI, Auteur Article en page(s) : p.1880-1892 Langues : Anglais (eng) Mots-clés : auditory feedback  autism spectrum disorder  motor control  prosody  social competence  speech production  vocal pitch Index. décimale : PER Périodiques Résumé : Autism spectrum disorder (ASD) is a developmental disorder characterized by persistent deficits in social communication and interaction. Speech is an important form of social communication. Prosody (e.g. vocal pitch, rhythm, etc.), one aspect of the speech signal, is crucial for ensuring information about the emotionality, excitability, and intent of the speaker, is accurately expressed. The objective of this study was to gain a better understanding of how auditory information is used to regulate speech prosody in autistic and non-autistic children, while exploring the relationship between the prosodic control of speech and social competence. Eighty autistic (M = 8.48 years, SD = 2.55) and non-autistic (M = 7.36 years, SD = 2.51) participants produced vocalizations while exposed to unaltered and frequency altered auditory feedback. The parent-report Multidimensional Social Competence Scale was used to assess social competence, while the Autism-Spectrum Quotient and the Autism Spectrum Rating Scales were used to assess autism characteristics. Results indicate that vocal response magnitudes and vocal variability were similar across autistic and non-autistic children. However, autistic children produced significantly faster responses to the auditory feedback manipulation. Hierarchical multiple regressions indicated that these faster responses were significantly associated with poorer parent-rated social competence and higher autism characteristics. These findings suggest that prosodic speech production differences are present in at least a subgroup of autistic children. These results represent a key step in understanding how atypicalities in the mechanisms supporting speech production may manifest in social-communication deficits, as well as broader social competence, and vice versa. Autism Res 2020, 13: 1880-1892. © 2020 International Society for Autism Research and Wiley Periodicals LLC LAY SUMMARY: In this study, autistic and non-autistic children produced vowel sounds while listening to themselves through headphones. When the children heard their vocal pitch shifted upward or downward, they compensated by shifting their vocal pitch in the opposite direction. Interestingly, autistic children were faster to correct for the perceived vowel sound changes than their typically developing peers. Faster responses in the children with ASD were linked to poorer ratings of their social abilities by their parent. These results suggest that autistic and non-autistic children show differences in how quickly they control their speech, and these differences may be related to the social challenges experienced by autistic children.
