Purpose: The spatiotemporal index (STI) is a widely used approach for measuring speech pattern stability across multiple repetitions of a stimulus. In this study, we examine how methodological choices in the implementation of the STI (including the number of repetitions, length of stimuli, and parsing procedure) can affect its value. Method: To…

Background: The impact of hearing impairment is typically studied in terms of its effects on speech perception, yet this fails to account for the interactive nature of communication. Recently, there has been a move towards studying the effects of age-related hearing impairment on interaction, often using referential communication tasks; however,…

We investigated the effect of part of speech adoption on the utterance length of Mandarin-speaking children. A total of 209 typically developing Taiwanese children aged 3-6 years participated in the study. They included 90 boys and 119 girls recruited from preschools in Miaoli City, New Taipei City, and Taipei City. We collected children's…

In this dissertation, I investigate how people navigate ambiguity in everyday speech, with a focus on quantifier-negation sentences. Combining corpus analysis, behavioral experiments, and computational modeling in the Rational Speech Act framework, I explore preferred interpretations of quantifier-negation and examine the contexts and prosodies…

Purpose: This study examined speech breathing during two connected speech tasks in children with cerebral palsy (CP) and typically developing (TD) peers. Understanding how the respiratory system supports speech production during various speech tasks can help researchers construct appropriate models of speech production and clinicians remediate…

This dissertation examines reported speech production among undergraduate college students with a history of developmental language disability (DLD) compared to controls with a history of typical language development (TD). 59 people participated across two separate studies. Study 1 involved a reanalysis of previously recorded in-person dyadic…

Background: The current literature suggests a link between dummy (or pacifier) use and a number of both positive and detrimental consequences. Positive consequences include soothing effect and protection from sudden infant death syndrome (SIDS), while negative ones include increased risk of otitis media and dental malformation. However, there is…

In this article, focus is on students' oral production in two classrooms in Swedish for immigrants (SFI). The study focuses on practices with interaction patterns where students are involved in negotiation of meaning. Theoretical basis is the importance of interpersonal interaction for language development, with a focus on students' use of varied…

Purpose: The purpose of this study was to investigate how general, implicit instructions with auditory-perceptual emphasis; specific, explicit instructions with biomechanical focus; or both affect learning of oral-nasal balance control in speech. Method: Thirty healthy, vocally untrained participants were assigned to one of three instructional…

This study formalizes and compares two major hypotheses in speakers' choices of referring expressions: the topicality model that chooses a form based on the topicality of the referent, and the rational model that chooses a form based on the informativity of the form and its speech cost. Simulations suggest that both the topicality of the referent…

The significance of producing socially appropriate utterances, not just linguistically correct ones, has given rise to a plethora of studies on speech acts. In this regard, the performance of second and foreign language learners against the norms of the target language and the factors affecting them have yet to be thoroughly investigated. To…

Purpose: Evidence increasingly indicates that people with developmental stuttering have auditory perception deficits. Our previous research has indicated similar but slower performance in categorical perception of the speech sounds under the quiet condition in children who stutter and adults who stutter (AWS) compared with their typically fluent…

Purpose: We sought to establish normative growth curves for intelligibility development for the speech of typically developing children as revealed by objectively based orthographic transcription of elicited single-word and multiword utterances by naïve listeners. We also examined sex differences, and we compared differences between single-word…

The present article focuses on studying metacommunication as a multi-dimensional self-reconfiguration endless symbolic process and its mechanisms of realising and optimising dynamic speech influence in German dialogue discourse within the anthropocentric framework of pragmalinguistics. Special emphasis has been laid on revealing the functional…

Two laboratories have reported that children with ASD are less likely than their typical peers to fill pauses with "um" but their use of "uh" is unaffected (Irvine et al., J Autism Dev Disord 46(3):1061-1070, 2016; Gorman et al., Autism Res 9(8):854-865, 2016). In this brief report, we replicated this finding by comparing the…
