 VOICE SECTION COMBINATIONS :

Voice files created by the PC base developing system are stored in the built-in EPROM of the

aP23682/341/170/085 chip as a number of fixed length Voice Blocks. Voice Blocks are

then selected and grouped into Voice Groups for playback. Up to 1024 Voice Groups are allowed.

A Voice Blocks 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 :

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 block :

B1 = “How”

B2 = ”are”

B3 = ”You”

B4 = Sound Effect

B5 = Music1

B6 = Music2

Voice Blocks are grouped together using Voice Table to form Voice Group for playback:

Group no.
