Method and apparatus for intelligible fast forward and reverse playback of time-scale compressed voice messages |
摘要 |
A method and apparatus for providing intelligible fast forward and reverse playback of messages which include time-scale compressed speech using a time scale modification technique. A receiver (2604) receives (2902) a message including speech compressed at a predetermined compression rate and a message rate identifier which identifies the predetermined compression rate which are then stored in a memory by a processor (2610). The processor (2610) processes (2912) the stored message to time-scale expand the compressed speech at an expansion rate that is equal to the predetermined compression defined by the message rate identifier so as to produce a normal speech playback speed. The processor (2610) also processes (3000, 3100) the stored message to time-scale expand the compressed speech at an expansion rate that is lower than the predetermined compression rate defined by the message rate identifier, so as to produce a perceptibly increased speech playback speed.
