简 介:W528SXX ADPCM VOICE SYNTHESIZER (PowerSpeech)
GENERAL DESCRIPTION
The W528xxx family are programmable speech synthesis ICs that utilize the ADPCM coding method to generate all types of voice effects. The W528xxx's LOAD and JUMP commands and four programmable registers provide powerful userprogrammable functions that make this chip suitable for an extremely wide range of speech IC applications. The W528xxx family includes 12 kinds of bodies which are the same except for the voice duration shown below: BODY Second BODY Second W528S03 3 Sec W528S20 20 Sec W528S05 5 Sec W528S25 25 Sec W528S08A 8 Sec W528S30 30 Sec W528S10 10 Sec W528S40 40 Sec W528S12 12 Sec W528S50 50 Sec W528S15 15 Sec W528S60 60 Sec
Note: The voice durations are estimated by 6.4KHz sampling rate.
