Phonation occurs when vocal fold vibrations are initiated and maintained by an interaction between the respiratory and phonatory systems [1]. The vocal folds must be in good condition for the voice to be satisfactory. Pathological conditions of the vocal folds are associated with voice deterioration. Voice disorders include alterations in vocal fold closure or muscle activation during vocal fol...

Facial, olfactory, and vocal cues may advertise women's fertility. However, most of the evidence for this proposal has come from studies of changes in young adult women's attractiveness over the menstrual cycle. By contrast with this emphasis on changes in attractiveness over the menstrual cycle, possible changes in women's attractiveness over their lifespan have received little attention. The ...

OBJECTIVES/HYPOTHESIS The primary objective of this study is to assess the adequacy of clinical and laboratory-based phonomicrosurgical training in otolaryngology residency programs using a self-report survey. The study aims to establish whether there is a need and desire for focused surgical training in phonomicrosurgery. STUDY DESIGN Self-report Internet-based questionnaire. METHODS An an...

The acoustic characteristics of so-called 'dist' tones, commonly used in singing rock music, are analyzed in a case study. In an initial experiment a professional rock singer produced examples of 'dist' tones. The tones were found to contain aperiodicity, SPL at 0.3 m varied between 90 and 96 dB, and subglottal pressure varied in the range of 20-43 cm H2O, a doubling yielding, on average, an SP...

The face and voice can independently convey the same information about emotion. When we see an angry face or hear an angry voice, we can perceive a person's anger. These two different sensory cues are interchangeable in this sense. However, it is still unclear whether the same group of neurons process signals for facial and vocal emotions. We recorded neuronal activity in the amygdala of monkey...

Nonlinear vocal fold dynamics arising from asymmetric flow formations within the glottis are investigated using a two-mass model of speech with asymmetric vocal fold tensioning, representative of unilateral vocal fold paralysis. A refined theoretical boundary-layer flow solver is implemented to compute the intraglottal pressures, providing a more realistic description of the flow than the stand...

Although speech is the most natural means for communication among humans, there are situations in which speech is impossible or inappropriate. Examples include people with vocal cord damage, underwater communications or in noisy environments. To address some of the limitations of speech communication, nonacoustic communication systems using surface electromyogram signals have been proposed. How...
