Description

The D6571E chip is a digital speech/signal processing subsystem that implements all functions of TRUESPEECH, speech compression and voice prompts, telephone line signal processing, flash memory management and True FULL Duplex SpeakerPhone' for an all digital answering machine. The D6571E is fully controlled by the system HOST through a simple interface protocol.  The HOST processor provides activation and control of all system functions such as speech recording and playback, DTMF and call progress tone detection, DTMF and tone generation, and voice prompting.
 
The fully digital solution has no moving parts, yielding high reliability.  The chip's programmability enables a full range of answering, recording and playback features for the end user.  The D6571E is a single-chip, digital signal processor that includes all of the necessary circuitry to interface with an external HOST, flash memory, and codec.
