I'm on a miserable dialup, so's I can't watch your YouTube video. But, I've had quite a few copies of the good Doctor packaged with several of my older CLI sound cards. IIRC they were all the same.
Heh, I used to get a "PARITY ERROR!!!" all the time 😉 🤣!
(edit) A side note: The "Sound and Graphics Upgrade" for Flight Simulator v4.0b used a modified version of the SBTalker "BLASTER.DRV" (that's what Dr. Sbaitso uses for the speech synth) that allowed for spoken speech-synthesized air traffic control communications within the sim. One problem is that it really made FS4's framerate quite choppy and to stutter.
Decades ago, I found that it was a simple matter of a hex-edit to the "BLASTER.DRV" file to force the driver to not utilize expanded memory... that solved the framerate and stuttering problems 😀
