Mobile telephone with voice data compression and recording features

Abstract

At providing a voice recording function for a mobile telephone, an additional circuit is small and the simplification of the circuit is possible, in case of that more voice data are preferred to be stored, the voice data of PHS are able to be further compressed and stored and the recording time is able to be increased and user himself can select the priority of the voice quality or the recording time, the above mentioned mobile telephone is provided. At the mobile telephone having plural voice encoding system, the mobile telephone provides an encoding/decoding feature, a voice data storing feature, a decoding and playback feature, a decoded data storing means and a data compression feature. The encoding/decoding feature provides a voice codec section, a controller and a recording key, and encodes and decodes the voice corresponding to a First voice encoding system. The voice data storing feature provides a voice data memory and stores encoded voice data. The decoding and playback feature provides the controller, the voice data memory, the recording key and three decoders, and the stored voice data are decoded and play backed at arbitrarily time. The decoding feature provides three decoders, the controller and the recording key, and decodes the stored data of the first voice encoding system at arbitrary time. The decoded data storing feature provides a data buffer storing the decoded data temporarily. The data compression feature provides a compression key, the controller and three encoders, and stores re-encoded data by a second voice encoding system in the voice data memory and compresses the data.
