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: This study was designed based on the need to verify the effectiveness of education in the vocology area concerning refining perceptual auditory skills. The purpose of the project described in this paper was to examine the effect of knowledge and skills training during a 2-week voice disorders graduate course on auditory-perceptual skills…

Bel canto singing style is a foundational cornerstone for vocal technique in choral ensemble classes. Yet there are reasons to question whether bel canto pedagogy alone can help students navigate the many different genres they sing as part of a diverse and balanced curriculum. This article examines the specific performance demands associated with…

Purpose: Patients with voice problems commonly report increased vocal effort, regardless of the underlying pathophysiology. Previous studies investigating vocal effort and voice production have used a range of methods to quantify vocal effort. The goals of the current study were to use the Borg CR100 effort scale to (a) demonstrate the relation…

Purpose: Auditory-perceptual evaluation is essential for the clinical assessment of voice disorders. Unstable perceptual voice evaluation has been shown for inexperienced listeners as compared to expert listeners. We examined the effects of perceptual training with external auditory anchors with and without immediate feedback on the evaluation of…

The current study investigated physical education (PE) student teachers' understanding of the vocal demands of their future profession, interest in participating in a voice-training program, and the current impact of the voice on quality-of-life by the "Voice Handicap Index" (VHI). Seventy-four PE student teachers completed a…

Purpose: The purpose of this study was to document typical vocal health characteristics (including voice-related activities, behaviors, and symptomatology) of young adults attending college and to determine lifetime and point prevalence rates of voice disorders. Method: Undergraduates at University of Wisconsin-Madison completed an anonymous…

Purpose: This investigation compared voice performance of student teachers across an academic semester in order to examine the effect of increasing demands on their voice. Method: A repeated measures design was applied to the data analysis: all participants were tested three separate times throughout the semester. The equipments used for…

Problem: There are no available studies on the prevalence, and distribution of speech disorders among Arabic speaking undergraduate students in Jordan. Method: A convenience sample of 400 undergraduate students at the University of Jordan was screened for speech disorders. Two spontaneous speech samples and an oral reading of a passage were…

The objective of this "pilot" investigation was to study the effects of the interaction of caffeine and water intake on voice as evidenced by acoustic and aerodynamic measures, to determine whether ingestion of 200 mg of caffeine and various levels of water intake have an impact on voice. The participants were 48 females ranging in age…

Vocal disorders are a very common occupation-related disease in teachers, though it has never been given enough attention in China. As a result, the occupational health care of professional voice users is surprisingly, undeveloped compared to the attention given to occupational hearing disorders or many other occupational symptoms.
