HT81003 - EasyVoice Speech

The EasyVoiceTM is a single-chip voice synthesizer LSI . The chip when triggered drives a speaker directly or through an external transistor with a PWM output. Negligible current is consumed in the standby state. The HT81xxx provides direct key or Matrix key input and 2 programmable FLAG outputs. Wi.
