<p>A speech communication system and method that has an improved way of handling information lost during transmission from the encoder to the decoder. More specifically, the improved speech communication system more accurately recovers from losing information about a frame of speech such as line spectral frequencies (LSF's), pitch lag (or adaptive codebook excitation), fixed codebook excitation and/or gain information. After estimating lost parameters in a lost frame and synthesizing the speech, the improved system matches the energy of the synthesized speech to the energy of the previously received frame.</p> |
