Background: Speech and language therapists (SLTs) provide interventions for inducible laryngeal obstruction (ILO) despite a current lack of evidence to inform intervention delivery. This study is the first step to develop an evidence-based intervention for ILO, using behaviour change theory and the Behaviour Change Technique Taxonomy version 1…

Purpose: This study collected measures of auditory-perceptual and oral somatosensory acuity in typically developing children and adolescents aged 9-15 years. We aimed to establish reference data that can be used as a point of comparison for individuals with residual speech sound disorder (RSSD), especially for RSSD affecting American English…

Purpose: The aim of the present study was to develop and validate a patient-reported outcome measure for gender incongruence specific to voice and communication parameters, including pitch, intonation, resonance, loudness, speech smoothness, speech clarity, word choice, facial expression, gesture, and posture. Method: The Utah Gender Presentation…

This study focuses on parental use of parentese: the acoustically exaggerated, clear, and higher-pitched speech produced by adults across cultures when they address infants. While previous research shows that parentese enhances language learning and processing, it is still unclear what drives the variability in the amount of parental parentese…

Background: Recent evidence suggests that speech substantially changes in ageing. As a complex neurophysiological process, it can accurately reflect changes in the motor and cognitive systems underpinning human speech. Since healthy ageing is not always easily discriminable from early stages of dementia based on cognitive and behavioural…

Purpose: The goal of this study was to examine the effects of increases in vocal effort, without changing speech intensity, on respiratory and articulatory kinematics in young adults with typical voices. Method: A total of 10 participants completed a reading task under three speaking conditions: baseline, mild vocal effort, and maximum vocal…

Purpose: Auditory feedback is thought to contribute to the online control of speech production. Yet, the standard method of estimating auditory feedback control (i.e., reflexive responses to auditory-motor perturbations), although sound, requires specialized instrumentation, meticulous calibration, unnatural tasks, and specific acoustic…

Purpose: The spectral powers of the modulations of vocal fundamental frequency (f[subscript o]) less than 3 Hz (low-frequency power, LFP) and between 3 and 8 Hz (middle-frequency power, MFP) had been established to indicate the audiovocal feedback status and vocal efficiency of a speaker, and a resonant voice may enhance the auditory-vocal…

Purpose: Many children with developmental language disorder (DLD) also have difficulty with executive function. The presence of co-occurring deficits in language and executive function can obscure assessment results and lead to the implementation of ineffective interventions. It is also the case that inner speech, or the use of self-directed…

Purpose: This study compared the inter- and intrarater reliability of the percentage of consonants correct (PCC) metrics and the probe scoring system between an experienced and a less experienced rater and between two experienced raters. In addition, these outcome measures' ability to reflect changes following speech intervention was measured.…

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…

Purpose: Prior work suggests that voice onset time (VOT) may be impacted by laryngeal tension: VOT means decrease when individuals with typical voices increase their fundamental frequency (f[subscript o]) and VOT variability is increased in individuals with vocal hyperfunction, a voice disorder characterized by increased laryngeal tension. This…

Cross-linguistic influence has been observed across all domains of language. However, nothing is known about the role of cross-linguistic influence in bilingual speakers' use of vocal fry. Several recent studies have identified an upsurge in the use of vocal fry among female speakers of American English. We sought to identify cross-linguistic…

For decades, mindfulness practices have been studied and applied across professions such as health care, business, education, law, and counseling as a means to reduce workforce stress and improve patient/client outcomes. Literature describing applications and outcomes of mindfulness has been growing in the field of speech-language pathology. While…

Purpose: Delayed auditory feedback (DAF) interferes with speech output. DAF causes distorted and disfluent productions and errors in the serial order of produced sounds. Although DAF has been studied extensively, the specific patterns of elicited speech errors are somewhat obscured by relatively small speech samples, differences across studies,…
