Abstract/OtherAbstract:
Objectives. To determine heart rate influence on voice fundamental frequency under stress conditions. Methods. In 14 healthy volunteers, heart rate and blood pressure variables were analyzed during three classical autonomic tasks. Sustained voice samples were obtained to analyze F0. Results. Cold pressure test increased mean blood pressure, without effect on heart rate; isometric and mental tasks increased heart rate and blood pressure. Voice F0 was only affected by mental and cold ice tasks; it significantly correlated with the heart rate that occurred before and during every vocal emission. Discussion. Cardiovascular changes showed that subjects were significantly stressed during autonomic tasks. Heartbeat variations had a regular and significant influence on phonatory frequency, and this effect occurred during baseline and stress conditions.
