Tired? We Can Hear It in Your Voice #ASA190

Physical task stress affects the coordination between breathing and speaking, and vocal pitch, intensity, and pause structure are all sensitive to changes in breathing and effort. Pitch and intensity both increase, while intensity also becomes less stable and speech rate slows down. Understanding exactly how physical stress causes changes to vocal patterns can help train speech recognition systems, which often struggle with speech that differs from the average. Zahra Omidi will present her work on this as part of the 190th ASA Meeting.
