Abstract:
A voice encoding device, comprising:an encoder having, a first quantizing block configured to voice encode input voice signals, and a second quantizing block configured to non-voice encode and to compressively encode input non-voice signals, wherein said first and second quantizing blocks include processing blocks configured to quantize line spectral pair (LSP) coefficients generated by an input signal processor; a voice/non-voice signal identification unit configured to identify whether a signal input to said encoder is at least one of a voice signal and a non-voice signal and to output a determination result; and a multiplexer portion configured to multiplex respective outputs from said first quantizing block and said second quantizing block and to output the respective outputs to a transmission path, wherein said encoder includes a selector configured to select one of said first quantizing block and said second quantizing block in accordance with said determination result from said voice/non-voice signal identification unit, and said first quantizing block and said second quantizing block are configured to compressively encode the input voice and non-voice signals by using a common quantization table.
