Disclosed is a communication vocoder. An encoder and a decoder in a first format, and a decoder in a second format are formed in the communication vocoder. The encoder in the first format encodes voice signals into voice packets in the first format, and the decoder in the first format decodes the voice packets in the first format into voice signals. When voice packets in the second format are input to the communication vocoder, the decoder in the second format decodes the voice packets in the second format into voice signals. The decoders in the first and second formats are formed as subroutines in the communication vocoder.
