FUNCTION DESCRIPTIONS
I. Voice content
In coding procedure, voice sources are separated into voice sections with arbitrary length. The sample rate
of each section is selected as either 6K Hz or 8K Hz. Pause time of voice section is defined by each voice
section. The maximum pause time can not exceed duration of the playing part of voice section.
A complete trigger group is formed by combining source voice sections.
For example,
Group1: sec3+sec1+sec3+sec5.
Group2: sec4+sec1+sec2+sec2+sec5.
The maximum section combination number in a trigger group and the total available section combination
number for all trigger groups are limited. These limitations vary with devices as followed:
start of the section
end of playing part
end of the section
playing part of voice section
m second
pause of the section
