General Description
The HT85XXX family is a series of programma
ble speech synthesizers and tone generators de
signed for user-defined voice and melody
applications. It provides various sampling
rates and beats, tone levels, tempos for the
speech synthesizer and melody generator.
The HT85XXX series has a built-inhigh quality,
