I never knew exactly what governs the length of a Pause() call, but I
think of it as a Yield function and assume it lets through whatever is
explicitly waiting, or more accurately, gives all other processes a
chance to do what they think is important. But this is a guess, and
since the length of a Pause() does not seem to be variable for the
most part, I think I may be wrong.

That's helpful -- thanks. Could explain why the Delay calls were not
suppressing speech for me. Regarding Pause, do you think it waits for,
say, a sertain number of window messages to be processed by the active
window?
