Purpose: The excised canine larynx provides an advantageous experimental framework in the study of voice physiology. In recent years, signal processing methods have been applied to analyze phonations in excised canine larynx experiments. However, phonations have a highly complex and nonstationary nature corresponding to different proportions of…

Purpose: This study primarily aimed at observing the possible tissue mobilization on facial, neck, and chest tissues caused by different double source of vibration semioccluded vocal tract exercises (DSV-SOVTEs). Another goal was to inspect the degree of self-perceived sensation of a massage-like sensation. Method: Fifty-five participants engaged…

The most important question for anyone born in London is 'Are you a Cockney?' Only those born within the sound of Bow bells can truthfully answer the question with a resounding 'yes.' 'Cockney' is a term of pride in the heart of the East End, an area recently made internationally famous to a new audience due to the global success of the TV series…

Words influence cognition well before infants know their meanings. For example, three-month-olds are more likely to form visually based categories when exemplars are paired with spoken words than with sine-wave tones, a likely precursor to learning symbolic relations between words and their referents. However, it is unclear why words have these…

Background: Cervical auscultation has been used clinically as an augmentative procedure for swallow examination. Despite its frequent use for screening and preliminary assessment of swallowing, the usefulness of cervical auscultation is controversial due to a lack of sufficient research, particularly in quantifying swallowing sounds. Aims: To…

Purpose: The aim of this study was to assess the effect of eight different facemasks on speech perception and listening effort in listeners with normal hearing (NH) and hearing loss by manipulating both mask type and background noise levels. Method: Forty adults listened to Quick Speech-in-Noise Test sentences recorded by a female talker through…

Purpose: Mixed historical data on how listening effort is affected by reverberation and listener-to-speaker distance challenge existing models of listening effort. This study investigated the effects of reverberation and listener-to-speaker distance on behavioral and subjective measures of listening effort: (a) when listening at a fixed…

The acoustic characteristics typical of mainstream schools in England make it challenging for deaf or hard of hearing (DHH) children to perceive speech but assistive listening technologies can enhance speech perception. In this study, we explored decision making for the purchase and allocation of assistive listening technologies by heads of…

Background: Speech differences may occur between motor subtypes of Parkinson's disease (PD), but the literature remains limited. Aims: Examine speech characteristics in individuals with PD across the tremor-dominant, nontremor-dominant and mixed subtypes comparing to healthy controls. Methods and Procedures: A total of 115 individuals with PD were…

A growing body of literature supports the use of echoic prompts toward conditioning other functional language skills. However, many individuals with autism spectrum disorder do not emit echoic behavior. Identifying the prerequisite skills of an echoic repertoire may be beneficial for intervention planning and clinical decision making. A chart…

Background: The voice range profile (VRP) is an acoustic measurement in vocal function voice assessment. While several factors influencing VRP outcomes are known, the impact of body posture during VRP recordings remains unexplored. Aims: To investigate the effects of standing and sitting posture on VRP performance in vocally healthy individuals.…

Purpose: Understanding children's speech perception strategies in noise is very important for improving their living environment. Previous studies with adults reported that closing the eyes improves speech understanding in noise by increasing the activation of cortical systems involved in listening and attention, while increased cognitive load…

Localizing sounds in noisy environments can be challenging. Here, we reproduce real-life soundscapes to investigate the effects of environmental noise on sound localization experience. We evaluated participants' performance and metacognitive assessments, including measures of sound localization effort and confidence, while also tracking their…

Purpose: Developmental language disorder (DLD) is a multifaceted disorder. Recently, interest has grown in prosodic aspects of DLD, but most investigations of possible prosodic causes focus on speech perception tasks. Here, we focus on speech production from a speech amplitude envelope (AE) perspective. Perceptual studies have indicated a role for…

Purpose: The purpose of this study was to determine if there are age-related differences in semantic processing with linguistic and nonlinguistic masking, as measured by the N400. Method: Sixteen young (19-31 years) and 16 middle-aged (41-57 years) adults with relatively normal hearing sensitivity were asked to determine whether word pairs were…
