This is really a function of the browser platform you select rather than the

While including many features to support speech applications, VoiceXML and
it's dependent input (SRGS) and output (SSML) languages do not make any
assumptions that preclude their use in TDD applications any more than DTMF
applications are precluded.

In some ways a TDD VoiceXML browser is a less complicated "device" than a
speech browser. Text SSML content does not have to be rendered to speech,
merely the TDD protocol in use and the callers responses do not have a
"recognition" step - they can be passed directly to the SRGS interpreter.

That said I do not know of a TDD VoiceXML browser.

Subject: VXML support for hearing impaired (TDD) 


We have a requirement to design IVR application with TDD support. We are
planning to use VXML scripting for this. No where I came across VXML 2.0
specs providing TDD support for the hearing impaired. Does VXML 2.0 support
TDD modems ?
