Increasing evidence suggests that children with developmental dyslexia exhibit a deficit not only at the segmental level of phonological processing but also, by extension, at the suprasegmental level. However, it remains unclear whether such a suprasegmental phonological processing deficit is due to a difficulty in processing acoustic cues of…

Task-irrelevant speech impairs short-term serial recall appreciably. On the interference-by-process account, the processing of physical (i.e., precategorical) changes in speech yields order cues that conflict with the serial-ordering process deployed to perform the serial recall task. In this view, the postcategorical properties (e.g., phonology,…

Purpose: This study aims to examine the clear speaking strategies used by older children when interacting with a peer with hearing loss, focusing on both acoustic and linguistic adaptations in speech. Method: The Grid task, a problem-solving task developed to elicit spontaneous interactive speech, was used to obtain a range of global acoustic and…

Purpose: We examined the association between speech perception in noise (SPIN), language abilities, and working memory (WM) capacity in school-age children. Existing studies supporting the Ease of Language Understanding (ELU) model suggest that WM capacity plays a significant role in adverse listening situations. Method: Eighty-three children…

Purpose: The relationship between reading (decoding) skills, phonological processing abilities, and masked speech recognition in typically developing children was explored. This experiment was designed to evaluate the relationship between phonological processing and decoding abilities and 2 aspects of masked speech recognition in typically…

Purpose: Listening tests for emotion identification were conducted with 8-17-year-old children with hearing impairment (HI; N = 25) using cochlear implants, and their 12-year-old peers with normal hearing (N = 18). The study examined the impact of musical interests and acoustics of the stimuli on correct emotion identification. Method: The…

Refugees have received considerable attention in recent years, across academic, popular, and political spheres. Using a range of methodologies, the three articles in this dissertation illuminate several aspects of the linguistic and social lives of Chin refugees from Burma (Myanmar) now living in Indiana, U.S.A. This includes an examination of…

Dysphonia is considered to be a common hazard associated with occupational voice users. Teachers represent the highest percentage of clinical voice disorder patients. Voice injuries in teachers could result in lost wages due to missed work, additional costs for medications, therapy, and surgeries, and teacher attrition. The purpose of this study…

Purpose: This study investigates the production of voiceless alveolar and postalveolar fricatives and affricates by bilingual and monolingual children with hearing loss who use cochlear implants (CIs) and their peers with normal hearing (NH). Method: Fifty-four children participated in our study, including 12 Spanish-English bilingual CI users (M…

All language use reflects the user's social identity in systematic ways. While humans can easily adapt to this sociolinguistic variation, automatic speech recognition (ASR) systems continue to struggle with it. This dissertation makes three main contributions. The first is to provide evidence that modern state-of-the-art commercial ASR systems…

Information from auditory feedback plays an important role in speech motor control. This has been shown in particular in experiments that make real-time changes to speakers' own productions, which are fed back to them while speaking (e.g. Houde and Jordan 1998). In response, speakers change their articulations so that their own altered feedback…

Purpose: This study/paper aims to explore civic participation within multimodal expression. With the rise of content produced and circulated within participatory cultures online, there has been much attention raised regarding questions of audience and attention to this content. For example, does production of media content constitute having a…

This research analyzes the acoustic characteristics and conducts a perception test of Thai tones produced by Chinese learners learning Thai through the "Thai Tone Application". A comparison of Thai tones pronounced by 40 Chinese learners learning Thai at Nakhon Ratchasima Rajabhat University with 40 Thai native speakers was also…

This book presents the main findings of a study on school learning environments and student outcomes, which the World Bank conducted in 2019 in three regions of the Russian Federation. Using data collected through the [Organisation for Economic Co-operation and Development] OECD School User Survey and the pilot "Trends in Mathematics and…

Purpose: We wished to make a comparison of psychophysiological measures of listening effort with subjective and dual-task measures of listening effort for a diotic-dichotic-digits and a sentences-in-noise task. Method: Three groups of young adults (18-38 years old) with normal hearing participated in three experiments: two psychophysiological…
