VOICE SECTION COMBINATIONS
Voice files created by the PC base developing system are stored in the built-in EPROM of the
aP89341/170/085 chip as a number of fixed length Voice Blocks. Voice Blocks are then selected and
grouped into Voice Groups for playback. Up to 254 Voice Groups are allowed. A Voice Block Table
is used to store the information of combinations of Voice Blocks and then group them together to form
Voice Group.

Example of Voice Block Combination
DataSheet4U.com
Assume here we have three voice files, they are How are You?, Sound Effect and Music. Each of
the voice file is divided into a number of fixed length Voice Block and stored into the memory.
Voice File 1 - How are You?is stored in Voice Block B0 to B12.
Voice File 2 - Sound Effect is stored in Voice Block B13 to B15.
Voice File 3 - Music is Voice Block B16 to B40.
Voice Blocks are grouped together using Voice Table to form Voice Group for playback:

Voice Data Compression
Voice File data is stored in the on-chip EPROM as either 4-bit ADPCM or 8-bit PCM format. Voice
data stored as 4-bit ADPCM provides 2:1 data compression which can save 50% of memory space.
On the other hand, voice data are stored as 8-bit PCM format means no data compression is employed
but voice playback quality will be better.
