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…

Purpose: The purpose of this project is to assess the acoustical conditions in which optimal intelligibility and low listening difficulty can be achieved in real classrooms for elementary students, taking into consideration the effects of dysphonic voice and typical classroom noise. Method: Speech intelligibility tests were performed in six…

Purpose: This study aims to investigate the effects of dysphonic voice on speech intelligibility in Cantonese-speaking adults. Method: Speech recordings from three speakers with dysphonia secondary to phonotrauma and three speakers with healthy voices were presented to 30 healthy listeners (15 men and 15 women; M[subscript age] = 22.7 years) under…

Purpose: In this study, the authors aimed to determine the relationship between relative fundamental frequency (RFF) and listener perception of vocal effort in individuals with varying degrees of vocal hyperfunction. Method: Thirty women diagnosed with voice disorders commonly associated with vocal hyperfunction and 10 healthy women provided…

Purpose: To determine the effect of auditory anchors on judgments of overall severity (OS) and vocal effort (VE) in dysphonic speech when judgments are made by experienced and inexperienced listeners, and when self-rated by individuals with dysphonia (speaker-listeners). Method: Twenty individuals with dysphonia and 4 normal controls provided…

This study investigates the influence of linguistic experience on the perception of pathologically-disordered voices using 18 listeners of American English, which has allophonic breathiness, 12 listeners of Gujarati, which contrasts breathy and modal vowels, and 18 listeners of Spanish, which has neither allophonic nor phonemic breathiness.…

In this article, we discuss the relationship between instrumental and perceptual phonetic analyses. Using data drawn from typical and atypical speech production, we argue that the use of two-tier transcriptions, which can compare and contrast perceptual and instrumental information, is valuable both for our general understanding of the mechanisms…

The perceptual assessment of voice disorders by speech pathologists and interjudge reliability were investigated through screening of 160 children (4-14 years old). Results demonstrated poor interjudge agreement between the listeners and indicate a need for more objective measures in the identification of voice disorders. (Author/SEW)

This investigation compared 19 adolescents' perceptions of the nonspeech personality characteristics of voice-disordered and normal-speaking children. Listeners, who rated recorded speech samples, showed a significant tendency to judge the normal speakers more positively than the voice-disordered speakers. Results suggest developmental trends in…
