Résumé :

Objective We investigated vocal characteristics associated with physiologically determined stressful episodes by means of post-hoc acoustic analyses of speech recorded in a clinical setting. Our research addressed the understudied question of which vocal features may serve as cues naturally occurring stress and is the first to explore this issue in a pitch accent language. Methods The vocal profile of a single female patient interacting with a physician was analyzed with standard speech analysis software for acoustic indicators of stress-related arousal determined by galvanic skin response measurements. Results Vocal jitter, representing an aspect of voice quality perceived as hoarseness, appeared to increase during and immediately after skin conductance response intervals. Skin conductance levels during the response intervals were negatively correlated with acoustic features used to approximate the perception of voice unsteadiness (slope and standard deviation of fundamental frequency). Conclusion An acoustic analysis of vocal properties of speech uttered during independently detected skin conductance response intervals revealed individual patterns for some acoustic features linked to stress in earlier studies. Practice implications Non-invasive methods of arousal detection in physician-patient communication based on acoustic analyses of vocal profiles may, in combination with other analyses, help identify stressful events and thus improve the process of medical information gathering and decision-making.
