ABSTRACT:
A coded voice signal format converting apparatus is provided which is capable of converting a signal format of a coded voice signal by computations in reduced amounts. In the coded voice signal format converting apparatus, in a second coding device is employed a quantizing accuracy information converting section to which a first quantizing accuracy information output from a quantizing accuracy information decoding section in a first decoding device is input. Second mapping signal is quantized by a mapped signal coding section to produce a coded voice signal and the first quantizing accuracy information is converted so that it can be used by mapped signal coding section to determine a second quantizing accuracy information.
