So when you hear Echo speech, all but the last step, that of actually generating the sound you hear, was done in software running on the Apple.

Even if it did, it would almost certainly be written in 6502 assembly, the 6502 and its variants being the microprocessor used by Apple II computers. There was a version of the Echo for PC, but again, the Textalker software would probably have been written in 8086 assembly.

So if you wanted to use it in external applications you would have to find a way to get that emulation working for all the parts of the card (the TMS5220, the text-to-speech part, the audio output) and I'm not sure how that would work.
