The Making of a TRS-80 Voice Synthesizer - Talker/80

"New dimensions in voice synthesis for the iconic Trinity computer from 1977!

Talker/80 is a new speech (voice) synthesizer for the TRS-80 Model 1. It offers DECtalk-based natural sounding speech, and can emulate the "official" TRS Voice Synthesizer as well as the VS-100 Alpha Products voice synthesizer. The original software runs without changes / patches. Both the VS-100 and the TRS Voice Synthesizer utilized the Votrax SC-01 speech chip. The SC-01 is "emulated" by means of DECtalk here (phoneme mapping).

Everything is open source, including the firmware sources and Gerbers:"
