Purpose: Speech motor skill is refined over the course of practice, which is commonly reflected by increased accuracy and consistency. This research examined the relationship between auditory-perceptual ratings of word accuracy and measures of speech motor timing and variability at pre- and posttreatment in children with childhood apraxia of…

Purpose: Verbal working memory is poorer for children with hearing loss than for peers with normal hearing (NH), even with cochlear implantation and early intervention. Poor verbal working memory can affect academic performance, especially in higher grades, making this deficit a significant problem. This study examined the stability of verbal…

Purpose: Speech understanding in noise and horizontal sound localization is poor in most cochlear implant (CI) users with a hearing aid (bimodal stimulation). This study investigated the effect of static and less-extreme adaptive frequency compression in hearing aids on spatial hearing. By means of frequency compression, we aimed to restore…

Purpose: Despite the recommendation for cochlear implant (CI) processor use during all waking hours, variability in average daily wear time remains high. Previous work has shown that objective wear time is significantly correlated with speech recognition outcomes. We aimed to investigate the causal link between daily wear time and speech…

Purpose: This retrospective study aimed to amass large data sets to enable statistical comparisons of communication outcomes for infants receiving cochlear implants (CIs) before 9 months of age compared to groups who received their first CI between 9 months and 3.5 years of age. Method: Speech perception scores and experienced clinicians'…

Purpose: Three experiments were conducted to better understand the role of between-word coarticulation in masked speech recognition. Specifically, we explored whether naturally coarticulated sentences supported better masked speech recognition as compared to sentences derived from individually spoken concatenated words. We hypothesized that…

Purpose: This study investigated the effects of visually presented speech envelope information with various modulation rates and depths on audiovisual speech perception in noise. Method: Forty adults (21.25 ± 1.45 years) participated in audiovisual sentence recognition measurements in noise. Target speech sentences were auditorily presented in…

This study examined the effect of increasing visual perceptual load on auditory awareness for social and non-social stimuli in adolescents with autism spectrum disorder (ASD, n = 63) and typically developing (TD, n = 62) adolescents. Using an inattentional deafness paradigm, a socially meaningful ('Hi') or a non-social (neutral tone) critical…

A child's success in school relies on their ability to quickly grasp language and reading skills, the foundations of which are acquired even before entering a formal classroom setting. Previous studies in preschoolers have begun to establish relationships linking beat synchronization, preliteracy skills, and auditory processing. Beat…

Purpose: In the context of music and speech perception, this study aimed to assess the effect of variation in one of two auditory attributes--pitch contour and timbre--on the perception of the other in prelingually deafened young cochlear implant (CI) users, and the relationship between pitch contour perception and two cognitive functions of…

Purpose: Some speech recognition data suggest that children rely less on voice pitch and harmonicity to support auditory scene analysis than adults. Two experiments evaluated development of speech-in-speech recognition using voiced speech and whispered speech, which lacks the harmonic structure of voiced speech. Method: Listeners were 5- to…

The Headturn Preference Procedure (HPP) is widely used in infant research. Previous studies have shown that speech perception measures obtained with HPP are related to later language skills which may make them a potential instrument for an early detection of developmental language risks. The present study assessed the reliability and stability of…

Purpose: The goal of this study was to use speech resynthesis to investigate the effects of changes to individual acoustic features on speech-based gender perception of transmasculine voice samples following the onset of hormone replacement therapy (HRT) with exogenous testosterone. We hypothesized that mean fundamental frequency (f[subscript 0])…

The research built on the anthropological approach to text comprehension links philosophical and psycholinguistic perspectives of speech perception. The article analyzes the factors influencing adequate comprehension when perceiving foreign language oral speech, in terms of testees' approximately similar level of language competence and…

Purpose: The aims of the study were (a) to evaluate the effects of systematically varied factors of stimulus duration, interaural-level difference (ILD), and direction on perceptual and electrophysiological metrics of lateralization for fixed versus moving targets and (b) to evaluate the hemispheric activity underlying perception of fixed versus…
