You can go even farther backwards - SAM (Software Automated Mouth) on the C64 produced understandable weirdly accented speech with something like 10K code+data IIRC, and a 1Mhz 6502; see e.g. https://discordier.github.io/sam/ https://discordier.github.io/sam/ (though it did take all the CPU, because it did software based PCM on non-PCM supporting hardware.... if the there was just little more control of the waveform generators, it would likely have been possible with 1% CPU or so ...)
- thelazydogsback 6y agoYou could output speech on the TRS-80 (which didn't even have any analog outputs) by pulse-width modulating 0/1 bits on the cassette port -- in conjunction with the inherent RC circuit provided by the output circuitry and speaker, you could get barely understandable speech.
