Abstract

Previous studies have demonstrated the importance of both kinesthetic and auditory feedback for control of voice fundamental frequency (F 0). In the present study, a possible interaction between auditory feedback and kinesthetic feedback for control of voice F 0 was tested by administering local anesthetic to the vocal folds in the presence of perturbations in voice pitch feedback. Responses to pitch-shifted voice feedback were larger when the vocal fold mucosa was anesthetized than during normal kinesthesia. A mathematical model incorporating a linear combination of kinesthesia and pitch feedback simulated the main aspects of our experimental results. This model indicates that a feasible explanation for the increase in response magnitude with vocal fold anesthesia is that the vocal motor system uses both pitch and kinesthesia to stabilize voice F 0 shortly after a perturbation of voice pitch feedback has been perceived.
