AI Article Synopsis
- The study examines whether the frequency of consonant and vowel sounds varies in speech directed towards children compared to adults.
- It analyzes speech from 44 adults addressing four listener groups: children aged 6, 18, and 36 months, and adult listeners.
- Findings indicate significant differences in the use of various consonant manners and places when speaking to different age groups, contributing to understanding phonological input frequency for language development.
Article Abstract
The purpose of the current study was to revisit a controversial topic: whether frequencies of phonological consonant and vowel classes differ in speech directed to children and to adults. In addition, the current study investigated whether the frequency of phonological consonant and vowel classes changes with children's increasing chronological and/or developmental age. This study analyzed speech input from 44 adults to four different age groups of listeners (i.e., three groups of children at 6, 18, and 36 months of age and one group of adult listeners) in terms of frequency of occurrence of consonant and vowel classes. Results revealed that consonant stop, nasal, fricative and glide manner classes as well as all four consonant place classes were significantly different in speech directed to the four different age groups. A perspective is discussed to better understand the nature of frequency input of phonological sound classes.

Impact of High- and Low-Pass Acoustic Filtering on Audiovisual Speech Redundancy and Benefit in Children.

Objectives: To investigate the influence of frequency-specific audibility on audiovisual benefit in children, this study examined the impact of high- and low-pass acoustic filtering on auditory-only and audiovisual word and sentence recognition in children with typical hearing. Previous studies show that visual speech provides greater access to consonant place of articulation than other consonant features and that low-pass filtering has a strong impact on perception on acoustic consonant place of articulation. This suggests visual speech may be particularly useful when acoustic speech is low-pass filtered because it provides complementary information about consonant place of articulation.

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.

Introduction: Lateral temporal neural measures (Na and T-complex Ta and Tb) of the auditory evoked potential (AEP) index auditory/speech processing and have been observed in children and adults. While Na is already present in children under 4 years of age, Ta emerges from 4 years of age, and Tb appears even later. The T-complex has been found to be sensitive to language experience in Spanish-English and Turkish-German children and adults.

Objectives: The SARS-CoV-2 pandemic required the use of personal protective equipment (PPE) in medical and social contexts to reduce exposure and prevent pathogen transmission. This study aims to analyse possible changes in voice and speech parameters with and without PPE.
Methods: Speech samples using different types of PPE were obtained.

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.
