I don't recall hearing about it, but the pictures interested me.
I think the missing 24pin chip is a Votrax SC-02 phoneme generator.
Also present are two SN76489 complex sound generators, 3 LM386 audio amps, one for each sound source, a clock generator & glue logic. The only unknown is the crystal frequency (guessing perhaps colorburst?).
The 16pin sockets seem to match the OSI head end card interface.
I wonder what software was available for this?
{I attached the photos for posterity since they will expire off ebay eventually}

I think I have assembly instructions for this board. Let me see if I can figure out where I put it...
