What about the scenario where 2 vendors support the same gender, age,
language etc and the script writer specifically wants to use vendor #1?
Is the "name" of the voice recommended to be used as the distinguishing
factor? Can we assume that this "name" will be unique across all

I can't speak for W3C of course, but I can't imagine how being able to
specify a TTS vendor would be portable, or even belong in the spec.  I
would think this is a platform specific extension.
The way we handle it is our TTS server can be configured to start an
arbitrary number of TTS engines (from various vendors).  But the script
writer can only access them based on speech markup elements/attributes.
Namely "voice", "gender", "age", "language", etc...  That way, if we
change the vendor for the "Adult Female", the script writer doesn't know
(or in most cases care).

	In VXML, if we're using TTS via the prompt element, there could
be a
	variety of vendors a user could use to perform TTS. The VXML 2.0
	does not provide a mechanism to specify which vendor/product to
use. Is
	there a recommended way to specify this? Are there plans to add
this to
	future VXML versions?
