Voice recording and/or reproducing method and apparatus for reducing a deterioration of a voice signal due to a change over from one coding device to another coding device

摘要

A voice recording and/or reproducing device includes a plurality of coders having different bit rates for coding voice to provide coded voice data, a voice recording mode change over switch for selecting one of the plurality of coders, and a system controller. The system controller stores coding selection data obtained by the change over of the voice recording mode and coded voice data obtained from the selected coder, to a storing medium, and reduces a deterioration of the voice due to the change over. The voice recording and/or reproducing device also includes a detector for detecting the coding selection data, and a plurality of decoders for decoding the coded voice data at the bit rate corresponding to the detected coding selection data.
