Direct linkPark, Yeonggwang; Anand, Supraja; Gifford, Sophia M.; Shrivastav, Rahul; Eddins, David A. – Journal of Speech, Language, and Hearing Research, 2023
Purpose: Acoustic and perceptual quantification of vocal strain has been a vexing problem for years. To increase measurement rigor, a suitable single-variable matching stimulus for strain was developed and validated, based on the matching stimulus used previously for breathy and rough voice qualities. Method: A set of 21 comparison stimuli for a…

Park, Yeonggwang; Anand, Supraja; Kopf, Lisa M.; Shrivastav, Rahul; Eddins, David A. – Journal of Speech, Language, and Hearing Research, 2022
Purpose: Dysphonic voices typically present multiple voice quality dimensions. This study investigated potential interactions between perceived breathiness and roughness and their contributions to overall dysphonia severity. Method: Synthetic stimuli based on four talkers were created to systematically map out potential interactions. For each…

Park, Yeonggwang; Anand, Supraja; Ozmeral, Erol J.; Shrivastav, Rahul; Eddins, David A. – Journal of Speech, Language, and Hearing Research, 2022
Purpose: Vocal roughness is often present in many voice disorders but the assessment of roughness mainly depends on the subjective auditory-perceptual evaluation and lacks acoustic correlates. This study aimed to apply the concept of roughness in general sound quality perception to vocal roughness assessment and to characterize the relationship…
