Abstract:
A method of pitch corrected speed control (PCSC) playback in which a decoder rate controller receives a desired playback speed from a PCSC controller and determines the number of decoded digital audio samples stored in a buffer. The rate controller then determines the required number of execution times of a parametric speech decoder based on the desired playback speed and the number of decoded samples stored in the buffer. The parametric speech decoder is then executed the determined number of times.
