Hi Bob -
I've used SAPI 4 & 5 to enable Rev speech synthesis on Windows, and
haven't found any problems on the surface. I'm not doing anything too
fancy with speech, just speaking unmodified English text so far.
As you may have already discovered, there are third-party voices
available whose quality completely eclipses MS and Apple voices. I don't
know a lot about the licensing details as I'm just at the beginning of
the selection process myself, but there are some good ones out there.
Here's a quick one I've tried:
http://cepstral.com/
They have downloadable voices for Mac. Windows, Linux. Languages include
English, Americas Spanish, Canadian French, Italian, and others.
Here's a list of other resources. Some have products that support
text-to-speech (TTS) in phone sytems, others support TTS in cars, some
support it in computers:

What's the best English text to speech engine for Windows? I see there
are ones from Microsoft, WinSpeech, Lernout & Hauspie, AT&T, and maybe
others.
Are there others for Spanish, Portuguese and French ?
Also, through searching I see references to SAPI 4.0, SAPI 5.0 and SAPI
5.1 (I assume) standards for these engines. Are there any problems
associated with a particular version and a release of Windows ?
Tnx, Bob...
