Abstract:
1. A voice decoder comprising: a first voice decoding circuit which is specialized for decoding at least one encoded narrow band voice signal; a second voice decoding circuit which is specialized for decoding at least one encoded wide band voice signal; and a band determination circuit which determines whether a target signal to be decoded is an encoded narrow band voice signal or an encoded wide band voice signal based on data solely within the encoded narrow band voice signal or the encoded wide band voice signal that forms the target signal, and wherein: said band determination circuit supplies said first voice decoding circuit with the target signal in a case where it is determined that the target signal is the encoded narrow band voice signal, and supplies said second voice decoding circuit with the target signal in a case where it is determined that the target signal is the encoded wide band voice signal; said first voice decoding circuit decodes the target signal supplied from said band determination circuit; and said second voice decoding circuit decodes the target signal supplied from said band determination circuit.
