Abstract
Several acoustical measures have been used in the past to evaluate vocal effort. They are useful in evaluating occupational risk for teachers or other occupational voice users. Analysis of vocal onsets has been used to show vocal effort in spasmodic dysphonia. Acoustical measures are also used in clinical speech-language pathology as an inexpensive and noninvasive ways of evaluating pathology severity and tracking therapy progress. In this presentation, a single acoustic parameter based on relative fundamental frequencies of glottal pulses following voiceless consonants (the onset coefficient) is used to evaluate vocal effort in response to changes in background noise and reverberation time within speaking environments. Analysis shows that males and females have similar vocal effort levels in the most typical acoustical conditions. However, females respond to louder background noise and longer reverberation times with more vocal effort than males.
