His software sang the words of God. Then it went silent

Judging by the sample wav at the end, someone might be able to use Software Activated Mouth. They sound pretty much identical, so I assume Commodore either used the DEC voice engine, or modeled after it.

They share the exact same abilities as well. There is a manual that describes how to get every possible phoneme out of it. Instead of spelling like normal words, there are letter combinations and numbers to denote pitch and speed, etc.

I wonder if anyone had tried to get it running on Wine. If they have a working Windows binary, it should work just fine for decades to come.
