Modulation Spectrum for Pitch and Speech Pause Detection

Olaf Schreiner

This paper describes a new approach to the speech pause detection problem. The goal is to safely decide for a given signal frame whether speech is present or not in order to switch an automatic speech recognizer on or off. The modulation spectrum is introduced as a method to determine the amount of voicing in a signal frame. This method is tested against two standard methods in pitch detection.
