RE: Subscribed earlier

The short of it is that OpenVXI doesn't.  VXML uses the speech markup from SSML.  Specifically, the <prosody> element would allow the application writer to specify rate, volume, pitch and range.  Using the <voice> element, things like gender and age can be specified.  Ultimately, it is up to the TTS engine (and possibly your platform).  For example, if the TTS engine you use doesn't support SSML, then you (as the integrator) would have to translate SSML into something it could understand.

Hi,
 
I noticed that part of the VXML 2.0 spec. on Accessibility reads as follows:
 
"Enable users to control the length of time before timeout, the speaking rate of synthesized speech, and other such variables that provide a little extra time to respond or complete an input action, particularly when the VoiceXML Interpreter Context has detected that the user is using an ancillary device instead of listening or speaking. These are especially useful for users with cognitive disabilities."
 
My question is:
 
how does the VXML spec support controlling "the speaking rate of synthesized speech" in the above context?
 
Best regards,
