Purpose: This scoping review considers the acoustic features of a clear speech register directed to nonnative listeners known as foreigner-directed speech (FDS). We identify vowel hyperarticulation and low speech rate as the most representative acoustic features of FDS; other features, including wide pitch range and high intensity, are still under…

Purpose: This study investigated the categorical perception of Mandarin tones and consonant aspiration contrasts in babble noise among adults and adolescents aged 12-14 years, and explored the association between working memory and categorical perception. Method: Twenty-four adults and 20 adolescents with Mandarin as their native language were…

This article describes literacy competence in the narratives of toddlers and investigates how they make use of different modalities, like gestures, sounds and physical actions. The body phenomenology of Merleau-Ponty serves as a theoretical frame for the researcher's lens, which is an A/r/tographer's lens applied in multimodal narrative analysis.…

Purpose: The Motor Planning Theory of Prosody and reading prosody research indicate that "out of the blue" oral reading, as practiced in clinical and research settings, invokes surface rather than covert prosody, particularly when readers are recorded, less skilled, and/or speech impaired. Warm-up is not considered in passage reading for…

This study investigates the acoustic realizations of English phonemic contrasts by Korean EFL learners, comparing their productions with those of native English speakers. Focusing on the segmentally correct production, the research aims to determine if Korean learners' acoustic properties align with those of native speakers, influenced by second…

It has been proposed that second language (L2) learners differ from native speakers in processing due to either influence from their native language or an inability to integrate information from multiple linguistic domains in a second language. To shed new light on the underlying mechanism of L2 processing, we used an event-related potentials…

Purpose: Phonations into a tube with the distal end either in the air or submerged in water are used for voice therapy. This study explores the effective mechanisms of these therapy methods. Method: The study applied a physical model complemented by calculations from a computational model, and the results were compared to those that have been…

Purpose: The purpose of this study was to assess changes in autonomic, behavioral, and acoustic measures in response to social stress in adults who stutter (AWS) compared to adults who do not stutter (ANS). Method: Participants completed the State-Trait Anxiety Inventory (Speilberger, Gorsuch, Luschene, Vagg, & Jacobs, 1983). In order to…

Critical analyses of experimental music and free improvisation have uncovered multiple educational benefits embedded within this broad collection of genres. However, by rooting this work primarily within formal classrooms, scholars have yet to discover how musicians conceptualise teaching and learning within communities outside of schools. To…

Purpose: This study explored the role of auditory feedback in the regulation of oral-nasal balance in speakers of Brazilian Portuguese. Method: Twenty typical speakers of Brazilian Portuguese (10 male, 10 female) wore a Nasometer headset and headphones while continuously repeating stimuli with oral and nasal sounds. Oral-nasal balance was…

This paper reports the findings of a three-year descriptive research investigation into postgraduate level students' perceptions of the strengths and weaknesses of audio feedback for assessment. Overall, results indicated that students positively received audio feedback. Particular strengths of audio feedback included it being more personalised…

We assessed the effects of singing in two venues on acoustic and perceptual measures of performances by an SATB choir (N = 28) as it sang in three spacing conditions, on two different riser unit heights, with data acquired from four microphone locations in each hall. Among primary acoustic results, long-term average spectra measures yielded a…

Purpose: Degraded speech intelligibility in background noise is a common complaint of listeners with hearing loss. The purpose of the current study is to explore whether 2nd formant (F2) enhancement improves speech perception in noise for older listeners with hearing impairment (HI) and normal hearing (NH). Method: Target words (e.g., color and…

Speech perception in noise remains challenging for Deaf/Hard of Hearing people (D/HH), even fitted with hearing aids or cochlear implants. The perception of sentences in noise by 20 implanted or aided D/HH subjects mastering Cued Speech (CS), a system of hand gestures complementing lip movements, was compared with the perception of 15 typically…

Purpose: Speech recognition deteriorates with hearing loss, particularly in fluctuating background noise. This study examined how hearing loss affects speech recognition in different types of noise to clarify how characteristics of the noise interact with the benefits listeners receive when listening in fluctuating compared to steady-state noise.…
