Young normal-hearing (YNH) and older normal-hearing (ONH) listeners identified vowels in naturally produced /bVb/ syllables and in modified syllables that consisted of variable portions of the vowel edges (silent-center [SC] stimuli) or vowel center (center-only [CO] stimuli). Listeners achieved high levels of performance for all but the shortest stimuli, indicating that they were able to access vowel cues throughout the syllable. ONH listeners performed similarly to YNH listeners for most stimuli, but performed more poorly for the shortest CO stimuli. SC and CO stimuli were equally effective in supporting vowel identification except when acoustic information was limited to 20 ms.

Evaluation of the Peripheral and Central Auditory Systems in Children and Adolescents Before and After COVID-19 Infection.
Children (Basel)
November 2024
Faculty of Medical Sciences, State University of Campinas, Campinas 13083-887, SP, Brazil.
Unlabelled: COVID-19 is an infectious disease caused by the SARS-CoV-2 virus. During and after COVID-19, audiovestibular symptoms and impairments have been reported.
Objectives: This study aimed to investigate the impacts of COVID-19 on the peripheral and central auditory systems of children and adolescents following the acute COVID-19 phase based on behavioral, electroacoustic, and electrophysiological audiological assessments.
Redundant voicing and register in Mnong Râlâm.
Phonetica
January 2025
Hanoi National University of Education, Hanoi, Vietnam.
Mnong Râlâm is a South Bahnaric language (Austroasiatic) that is traditionally described as preserving a voicing contrast in onset obstruents, contrary to other languages of the Mnong/Phnong continuum. Acoustic results yield evidence that this voicing distinction is less robust than previously suggested and is redundant with a register contrast realized on following vowels through modulations of F1 at vowel onset (and more limited variations of F2 and voice quality). A perception experiment also shows that F1 weighs heavier than closure voicing in identification.

This study (1) characterized the effects of channel interaction using spectral blurring, (2) evaluated an image-guided electrode selection (IGES) method aiming to reduce channel interaction, and (3) investigated the impact of electrode placement factors on the change in performance by condition. Twelve adult MED-EL (Innsbruck, Austria) cochlear implant recipients participated. Performance was compared across six conditions: baseline (no blurring), all blurred, apical blurred, middle blurred, basal blurred, and IGES.

Background/objectives: The present study investigates the reasons for better recognition of disyllabic words in Malayalam among individuals with hearing loss. This research was conducted in three experiments. Experiment 1 measured the psychometric properties (slope, intercept, and maximum scores) of disyllabic wordlists.

Purpose: Speech disorders associated with velopharyngeal dysfunction (VPD) are common. Some require surgical management, while others are responsive to speech therapy. This is related to whether the speech error is obligatory (passive) or compensatory (active).
