    • Voice recording and playback mode using the G.726 half-rate within the personal handy phone system (PHS). When a portable station within the PHS operates as a voice recorder (e.g., functioning as an answering machine), a cost effective system in accordance with the present invention is adapted to compress and store received voice/sound signals in order to increase the usage of limited memory resources provided within the portable station. The present invention also enables previously compressed and stored voice/sound signals to be decompressed and played back in various portable station playback modes. Specifically, the portable station receives a voice/sound signal in a full rate (e.g., 32 kilobits-per-second) 4-bit adaptive differential pulse code modulation (ADPCM) data format in compliance with the International Telecommunication Union (ITU) recommendation G.726. The present invention compresses this received voice/sound signal to a half rate (16 kilobit-per-second) 2-bit ADPCM data format in compliance with the ITU recommendation G.726 in order to increase the usage of the limited memory resources provided within the portable station. During a playback mode of the portable station, the present invention decompresses the previously compressed and stored voice/sound signal to facilitate its playback.
    • 录音和播放模式使用个人手机系统(PHS)内的G.726半速率。 当PHS内的便携式站作为语音记录器(例如,用作应答机)时,根据本发明的成本有效的系统适于压缩和存储接收到的语音/声音信号,以便增加使用 在便携式站内提供的有限的存储器资源。 本发明还使得先前压缩和存储的语音/声音信号能够以各种便携式电台播放模式被解压缩和重放。 具体来说,便携式电台以符合国际电信联盟(ITU)推荐G的全速率(例如,32千比特每秒)4位自适应差分脉码调制(ADPCM)数据格式接收语音/声音信号 .726。 本发明根据ITU推荐G.726将该接收到的语音/声音信号压缩到半速率(16千比特每秒)2位ADPCM数据格式,以便增加在内部提供的有限存储器资源的使用 便携式电台。 在便携式终端的回放模式期间,本发明解压缩先前压缩和存储的语音/声音信号以便于其播放。
