Efficient neural encoding of sound plays a critical role in speech and language, and when impaired, may have reverberating effects on communication skills. This study investigated disruptions to neural processing of temporal and spectral properties of speech in individuals with ASD and their parents and found evidence of inefficient temporal…

What are the vocal experiences of children growing up on Malakula island, Vanuatu, where multilingualism is the norm? Long-form audio-recordings captured spontaneous speech behavior by, and around, 38 children (5-33 months, 23 girls) from 11 villages. Automated analyses revealed most children's vocal input came from female adults and other…

Child-directed language can support language learning, but how? We addressed two questions: (1) how caregivers prosodically modulated their speech as a function of word familiarity (known or unknown to the child) and accessibility of referent (visually present or absent from the immediate environment); (2) whether such modulations affect…

Reading identities are the ways that a child constructs the self as a reader across contexts and time. This study examines the impact of language contexts on the reading identities of multilingual children. Participants were ten prekindergarten children participating in a Chinese-English family literacy programme with a parent or grandparent.…

Background: Little is known about the spontaneous speech characteristics of young children with language delay in Mandarin, relative to their peers. Until the recent development of standardized language assessments normed in China on Mandarin-speaking children, it was difficult to independently identify atypically developing children to study…

Purpose: Previous studies have shown that individuals who stutter exhibit abnormal speech perception in addition to disfluent production as compared with their nonstuttering peers. This study investigated whether adult Chinese-speaking stutterers are still able to use knowledge of statistical regularities embedded in their native language to…

The project "Making voice and Presence a Virtual Realistic Experience" is funded by "HessenHub - Network digital university teaching Hessen". At the Center for Foreign Language and Occupational Competencies (German: ZfbK) at the University of Giessen, a teaching concept for student teacher training was developed that includes…

Voice onset time (VOT) of aspirated stop consonants is marked by variability and systematicity in adult speech production. The present study investigated variability and systematicity of voiceless aspirated stop VOT from 161 two- to five-year-old talkers of American English and Cantonese. Overall, many aspects of child VOT productions parallel…

By encouraging elementary students to work collaboratively, they can gain essential skills such as perspective taking, conflict negotiation, and asking for and receiving assistance. Epistemic Network Analysis (ENA) is an analytic technique that provides an alternative to more typical approaches to analyzing and synthesizing coded dialogue. This…

Background: Successful communication is vital to quality of life. One group commonly facing speech and communication difficulties is individuals with intellectual disability (ID). A novel route to encourage clear speech is offered by mainstream smart speakers (e.g., Amazon Alexa and Google Home). Smart speakers offer four factors important for…

Much research in child speech development suggests that young children coarticulate more than adults. There are multiple, not mutually-exclusive, explanations for this pattern. For example, children may coarticulate more because they are limited by immature motor control. Or they may coarticulate more if they initially represent phonological…

Questionnaire design texts commonly recommend emphasizing important words, including capitalization or underlining, to promote their processing by the respondent. In self-administered surveys, respondents can see the emphasis, but in an interviewer-administered survey, emphasis has to be communicated to respondents through audible signals. We…

Comprehenders encounter a variety of syntactic structures through reading or spoken conversation. In some cases, sentences can be ambiguous and have more than one meaning. In "The spy saw the cop with the binoculars," one interpretation is that the spy is looking through the binoculars, while an alternative is that the cop has the…

The goal of this dissertation is to better understand the targets of vowels in speech production. Three experiments investigate vowel production in non-native speech, probing how new vowel categories, and thus targets, are formed. Three research questions are addressed: (1) Do vowels have articulatory targets (as predicted by Browman &…

This paper examines recent lexical expansion in New Zealand Sign Language (NZSL) in the context of change in the status of the language and ongoing contact with other (spoken and signed) languages. We categorised 917 new signs documented in the past five years according to their source, semantic field, and sign formation mechanism(s), both…
