在需要回放时，再由单片机控制提取RAM中的数据，通过D/A转换器将数字信号转换为模拟信号，通过功率放大器将语音信号还原后回放出来。

When this system needs to playback, data is gotten from RAM, and it transforms into the analog signal through the D/A switch. Moreover through the power amplifier, the voice signal can be recovered.

我只花了近两个月听取语音识别发射本人独家乙综合放大器。

I just spent the last two months listening to the ASR Emitter I Exclusive B integrated amp.
