PROBLEM TO BE SOLVED: To solve the problem that conventionally it is difficult to properly receive a non-voice signal by merely substituting a voice coding device in the device of the transmitting side with a voice coding device, which can properly transmit also a non-voice signal, because a voice decoder in the device of the receiving side is still of the conventional type. SOLUTION: The LSP (line spectrum pair) coefficient of an input signal is generated by a frequency parameter generating means 181, and when the input signal is the non-voice signal, the LSP coefficient is generated by bringing it close to the LSP coefficient of the voice signal. Then, the LSP coefficient is quantized by referring to the same LSP quantization code book 7. |
