Hi Jamal,
I imagine this code is greatly interesting to many people, I know some
newbies who like the speech feature one of the best in programming,
overall. Talking the stuff to a wave file and switching voices is a
little harder, requiring more method calls and collections. I have
sample code of that in PErl which should be relatively easy to
translate, too. Look for Speech.SpVoice twice and sampling rate once in
the following:

But can anyone tell me how to change pitch in a SAPI 5 synth? It sure is
not a property yet seems like a standard parameter in application
software such as screen readers.

Does anyone have sample code of a SAPI synth? I'd like to write one that
captures stuff to a text file, from Acrobat and Ms Reader, that is.

PS: Another good SAPI 5 example is the NVDA source that comes with the
app.
