Cognitive Predictors of Perception and Adaption to Dysarthric Speech in Older Adults.

Purpose: In effortful listening conditions, speech perception and adaptation abilities are constrained by aging and often linked to age-related hearing loss and cognitive decline. Given that older adults are frequent communication partners of individuals with dysarthria, the current study examines cognitive-linguistic and hearing predictors of dysarthric speech perception and adaptation in older listeners.

Method: Fifty-eight older adult listeners (aged 55-80 years) completed a battery of hearing and cognitive tasks administered via the National Institutes of Health Toolbox.

"1-800-Help-Me-With-Open-Science-Stuff": A Qualitative Examination of Open Science Practices in Communication Sciences and Disorders.

Purpose: The purpose of this qualitative study was to examine the perceptions of communication sciences and disorders (CSD) assistant professors in the United States related to barriers and facilitators to engaging in open science practices and identify opportunities for improving open science training and support in the field.

Method: Thirty-five assistant professors (16 from very high research activity [R1] institutions, 19 from institutions with other Carnegie classifications) participated in one 1-hr virtual focus group conducted via Zoom recording technology. The researchers used a conventional content analysis approach to analyze the focus group data and develop categories from the discussions.

Vowel Acoustics as Predictors of Speech Intelligibility in Dysarthria.

Purpose: This study sought to determine if alternative vowel space area (VSA) measures (i.e., novel trajectory-based measures: vowel space hull area and vowel space density) predicted speech intelligibility to the same extent as two traditional vowel measures (i.

The Reliability and Validity of Speech-Language Pathologists' Estimations of Intelligibility in Dysarthria.

This study examined the reliability and validity of speech-language pathologists' (SLP) estimations of speech intelligibility in dysarthria, including a visual analog scale (VAS) method and a percent estimation method commonly used in clinical settings. Speech samples from 20 speakers with dysarthria of varying etiologies were used to collect orthographic transcriptions from naïve listeners n=70 and VAS ratings and percent estimations of intelligibility from SLPs n=21. Intra- and interrater reliability for the two SLP intelligibility measures were evaluated, and the relationship between these measures was assessed.

Generalized Learning of Dysarthric Speech Between Male and Female Talkers.

Purpose Perceptual training is a listener-targeted means for improving intelligibility of dysarthric speech. Recent work has shown that training with one talker generalizes to a novel talker of the same sex and that the magnitude of benefit is maximized when the talkers are perceptually similar. The current study expands previous findings by investigating whether perceptual training effects generalize between talkers of different sex.
