This study is part of a series on speech-based first impressions of prelingually deaf cochlear implant (CI) users with differing speech intelligibility. Hiring managers with typical hearing (TH) rated CI users and TH young adults on various personality traits and suitability as job applicants after hearing recorded speech samples. Similar to prior…

Anxiety or nervousness is one of the affective factors that affects anyone learning and practicing English as a foreign language, especially when speaking the language. Anxiety in English speaking is commonly related to apprehension, fear, and worry that the learners experience when using the language. Most researchers in Indonesia studied…

Purpose: The purpose of this study was twofold: (1) to determine whether there are speech rhythm differences between preschool-age children who stutter that were eventually diagnosed as persisting (CWS-Per) or recovered (CWS-Rec) and children who do not stutter (CWNS), using empirical spectral analysis and empirical mode decomposition of the…

Studies employing multiple-schedule arrangements to bring social approaches (e.g., requesting attention, raising hand) under stimulus control have commonly used correlated contrived, continuous stimuli with at least one condition (e.g., displaying a green stimulus when attention is available and a red stimulus when it is not). Although imposing…

Speaking intelligibly is an important achievement in children's language development. How far do congenitally severe-to-profound hearing-impaired children who received a cochlear implant (CI) in the first two years of their life advance on the path to intelligibility in comparison to children with typical hearing (NH)? Spontaneous speech samples…

Purpose: Although speech-language pathologists have provided gender-affirming voice training for trans women since the 1970s, evidence for this training's effectiveness remains weak. Our study aimed to redress limitations of earlier studies and evaluate voice training effects on outcomes important to trans women. Method: Seventy-four trans women…

Schizophrenic discourse is characterized by thought disorder, or a lack of coherence, prompting substantial research into identifying and measuring the incoherent discourse of schizophrenics. Much of this research has examined short extracts of elicited spoken data and used researcher judgments. This study examines the connectedness of…

Most second language assessment researchers agree that interactional competence (IC) is an important part of the construct of oral communication. However, measurement of IC has proven challenging because at least one interlocutor is considered necessary to create an appropriate social context for test takers to demonstrate their IC. Including…

This study compared the acoustic properties of 26 (100% female, 100% monolingual) Danish caregivers' spontaneous speech addressed to their 11- to 24-month-old infants (infant-directed speech, IDS) and an adult experimenter (adult-directed speech, ADS). The data were collected between 2016 and 2018 in Aarhus, Denmark. Prosodic properties of Danish…

This full paper concerns an exploratory study that investigates students' reasoning about torsion. Mechanical reasoning is critical to engineering applications and yet students still struggle to accurately predict, analyze, and model mechanical systems using formal symbolic notations (i.e., formalizations). To understand the nature of students'…

For over four decades, International Teaching Assistants (ITAs) have faced criticism by undergraduate students for their linguistic and teaching abilities. One area of research on ITAs' linguistic abilities focused on their pronunciation and generally revealed non-standard patterns of segmental and suprasegmental features (Anderson-Hsieh et al.,…

There is a long-standing debate in the literature about the benefits that acoustic components of Infant Directed Speech (IDS) might have for infants' language acquisition. One of the highly contested features is vowel space expansion, which refers to the enlargement of the acoustic space between the corner vowels /i, u, a/ in IDS compared to Adult…

Purpose: Multiple methods have been suggested for quantifying syntactic complexity in speech. We compared eight automated syntactic complexity metrics to determine which best captured verified syntactic differences between old and young adults. Method: We used natural speech samples produced in a picture description task by younger (n = 76, ages…

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,…

Research on the acoustic characteristics of Infant Directed Speech (IDS) in North American English indicates that it is generally higher-pitched than Adult Directed Speech (ADS) and has unique prosodic characteristics, which is commonly found across many spoken languages. However, very little research has addressed another important aspect of…
