Application of auditory image model for speech event detection

Minoru Tsuzaki, Satomi Tanaka, Hiroaki Kato, Yoshinori Sagisaka

To provide an appropriate model for perception of temporal structures of speech, we applied a comprehensive computational model of the human auditory peripherals to detect changes in speech signals that potentially indicate arrivals of new events. In each tonotopic sub-band, an increase in the activation level was taken into account for the plausibility of a new event, while a decrease was ignored. The total contour obtained by integrating the sub-band information exhibited sharp peaks and dips compared to the loudness contour. A quantitative evaluation to estimate the speaking rate of natural speech also demonstrated that the event-plausibility model performs better than the loudness model.
