Abstract :
A speech speed control techniques are used in the various fields such as language training and audio instruments and so on. To realize the speech speed control, there is an easy way that changes a playback speed of a tape-recorder. However, the original speech quality is severely degraded by this method. Currently popular speech speed control method is to change the voice part duration of a speech signal while a pitch period remains. In this paper, we would like to propose a novel approach to change the speech speed due to altering the duration of output of band-pass components.
