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 spec
	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?
