IIRC, SAM uses formant synthesis combined with filters to simulate speech. The formants basically emulate vocal chords, while the filters simulate how the mouth shapes sounds. I’ve also looked into this before, but I didn’t get very far. Answer from GearBent on reddit.com

I just ported SAM (Software Automatic Mouth) to pure go. It worked!
It worked on my (linux) system for basic test cases, outputting direct to the audio card. I tried to feed it the lyrics to Stay Alive and I got a panic. But it does work. And man does it sound 8-bit. If nothing else this would make a good thing to mix into some chip tunes. More on reddit.com

July 24, 2019 -
Does anyone know how the text-to-speech used on the Commodore, i.e. Software Automatic Mouth, or SAM, actually synthesized the voice? Did it have any sort of recorded sample data? Did it just use additive synthesis? Or formant synthesis?
There's a github of someone's port of it to C here, although many of the variables, functions, and labels are just named based on their location in memory, not their function, so it still appears a black box.
