... ADPCM algorithm is used. The audio message is stored in a 512K bits on-chip EPROM which can store seconds of voice data at 6 KHz sample rate. The aP8821 eliminates the need of complicated circuitry in voice playback but still achieves high voice quality for different kind of sounds. Combinations in sections achieve longer playback duration. ...

... The entries of blocks for each group is truly random and without limitation. However, there is a limit in the total number of entries for 14 voice groups, which is 960 entries in aP8821 acceptable to allocate all entries into only one group or distribute out to other groups. It depends on how many groups of messages are required ...
