<p>The present invention provides a sound compression/decompression system and method which processes sound data, frame by frame, while transmitting information on special processing at the same time without degrading the bit rate. When a frame for special processing is transmitted in the form of a bit stream, this system sets the index value of the bit stream to a special value not used for normal processing, thus preventing the bit rate from being degraded. This system also contains information on special-processing in the non-index bits of the bit stream to implement various types of special processings. For example, a plurality of consecutive unvoiced frames may be transmitted in a one-frame bit stream. <IMAGE></p> |
