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 the time, the above mentioned mobile telephone is provided. At the mobile telephone having plural voice encoding system, the mobile telephone provides an encoding/decoding means, a voice data storing means, a decoding and playback means, a decoded data storing means and a data compression means. The encoding/decoding means 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 means provides a voice data memory and stores encoded voice data. The decoding and playback means provides the controller, the voice data are decoded and played back at arbitrarily time. The decoding means 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 means provides a data buffer storing the decoded data temporarily. The data compression means 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.
