EM20055A
3 SEC. VOICEYNTHESIZER IC
For examples:
The voice section is combined by one voice part and the corresponding pause part:
The duration of Pause is selected by mask option, and,
0 sec < Pause N < Voice N
The six voice sections are clustered to four groups. Each group corresponds to one TR pin. One group may
contain several voice sections. The same voice section may appear in different group.
The voice section in the group may appear multiple.
For examples:
Group 1: Sec1, Sec2, Sec3, Sec4, Sec5, Sec6.
Group 2: Sec2.
Group 3: Sec2, Sec2, Sec1, Sec3, Sec6, Sec6, Sec6, Sec5, Sec1.
Group 4: Sec6, Sec5, Sec4, Sec1.
The maximum appeared voice section number in four groups is 59.
Whenever the TR pin is triggered, the corresponding voice group will play voice sections in the triggered
group with preset sequence.
B). Programable Voice Volume & Playing Speed
The voice volume and playing speed is programable on EM20055A. The adjustment is before IC fabrication
(masked option).
For voice volume adjustment, EM20055A provides 4 steps for each section setting :
