ABSTRACT:
A voice decoder comprises the first voice decoding circuit which is specialized for decoding narrow band voice signal, the second voice decoding circuit which is specialized for decoding wide band voice signals, and a band determination circuit which determines whether a target signal to be decoded is a narrow band voice signal or wide band voice signal. The band determination circuit supplies the first voice decoding circuit with the target signal in a case where it is determined that the target signal is a narrow band voice signal, and supplies the second voice decoding circuit with the target signal in a case where it is determined that the target signal is a wide band voice signal. The first voiced decoding circuit decodes the supplied target signal. The second voice decoding circuit decodes the supplied target signal.
