This study examined two possible reasons underlying longitudinal increases in vowel identification by cochlear implant users: improved labeling of vowel sounds and improved electrode discrimination. The Multidimensional Phoneme Identification (MPI) model was used to obtain ceiling estimates of vowel identification for each subject, given his/her electrode discrimination skills. Vowel identification scores were initially lower than the ceiling estimates, but they gradually approached them over the first few months post-implant. Taken together, the present results suggest that improved labeling is the main mechanism explaining post-implant increases in vowel identification.

This paper explores the perception of two diachronically related and mutually intelligible phonological oppositions, the onset voicing contrast of Northern Raglai and the register contrast of Southern Raglai. It is the continuation of a previous acoustic study that revealed that Northern Raglai onset stops maintain a voicing distinction accompanied by weak formant and voice quality modulations on following vowels, while Southern Raglai has transphonologized this voicing contrast into a register contrast marked by vowel and voice quality distinctions. Our findings indicate that the two dialects partially differ in their use of identification cues, Northern Raglai listeners using both voicing and F1 as major cues while Southern Raglai listeners largely focus on F1.

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.

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.
