The vocal folds of male Rocky Mountain elk (Cervus elaphus nelsoni) are about 3 cm long. If fundamental frequency were to be predicted by a simple vibrating string formula, as is often done for the human larynx, such long vocal folds would bear enormous stress to produce the species-specific mating call with an average fundamental frequency of 1 kHz. Predictions would be closer to 50 Hz. Vocal ...

OBJECTIVE To identify a possible correlation between teachers vocal intensity and the noise in the classroom, as well as between vocal intensity and the symptoms of vocal tract discomfort before and after classes. METHODS 27 Elementary School I teachers participated in the study. We used the questionnaires "Vocal Production Condition of the Teacher" and "Vocal Tract Discomfort Scale - VTD" wh...

Vocal fold injection is a procedure that has over a 100 year history but was rarely done as short as 20 years ago. A renaissance has occurred with respect to vocal fold injection due to new technologies (visualization and materials) and new injection approaches. Awake, un-sedated vocal fold injection offers many distinct advantages for the treatment of glottal insufficiency (vocal fold paralysi...

BACKGROUND Postural correlates of vocal effort are rarely described in the literature, while they are extensively dealt with in speech therapy. OBJECTIVES This study aims at determining whether body movement is a side effect of vocal effort or an integral part of communication effort behavior. The answer to this question is mainly based on correlations between posture and phonation. METHOD ...
