VOICE SYNTHESIZER

The voice synthesizer is based on the V8600 Speech Synthesizer made by RC Systems. For more about RC Systems V8600. In SAPPHIRE, the voice synthesizer is powered off the +5V bus and can be powered on and off by the CPU using a simple power switching circuit. Some pull down circuits are used on the input signals to the voice synthesizer (see schematic)

The CPU communicates with the voice sythesizer using TTL, sending to the voice synthesizer ASCII text strings.
