Preliminary
Functional Description
The EasyVoice
TM
is voice synthesizer with
3-second voice capacity. A group of pre-recorded
voicesectionsisplayeduponreceiptofkeytrigger
input signals. Two FLAG signals are output
while playing voices.
The 3-sec voice capacity can be divided into sec-
tions of arbitrary length. Notice that the silence
length and end-pulse width are not included in
the memory.
By using Holtek s programming tools, the con-
tents and arrangement of sections, as well as
key features and FLAG output are all program-
mable before device fabrication.
The IC provides 2 key inputs (KEY1~KEY2),
KEY1 can be optioned as a direct, sequential
trigger key. Key 2 can be selected as a stop or a
direct key.
