Greetings:
I am hoping to generate speech data for the old NS MM45104 (Mozer) Digitalker chip; sources or binaries for an encoder or a complete description of the process would help the most.
A description of the technology (broadly) can be found in this patent:
which applies to a similar but somewhat different implementation from that used in the MM45104.
This site discusses the device implementing the technology described in the patent:
And here is that site's author's decoder program;
When time permits, I will try decoding the data from some speech ROMs that I have saved from an old product to see how close they come to the format described above. In any case encoding is much more difficult and the described format is known to be different from that used in the Digitalker chip.
Regards,
Michael
