Abstract: A voice encoding device according to the present invention includes an encoder having a first quantizing block suitable for voice encoding and a second quantizing block suitable for non-voice encoding and compressively encoding input signals, a voice/non-voice signal identification unit for identifying whether an signal input to the encoder is a voice signal or a non-voice signal and outputting a determination result, and a multiplexer portion for multiplexing respective outputs from the first quantizing block and the second quantizing block in order to output to a transmission path. In this case, the encoder has a selector for selecting either one of the first quantizing block or the second quantizing in accordance with the determination result from the voice/non-voice signal identification unit, and the first quantizing block and the second quantizing block compressively encode signals by using a same quantization table.
