Issues you raised and VBWG responses




Issue CR16-1
In section 4.1.5 you make the following statement:

"In the case where several prompts are queued, the bargein attribute of
prompt is honored during the period of time in which that prompt is

I am concerned about the scenario where a barge in *true* prompt is
by a barge in *false* prompt while waiting for speech input. I have not
encountered a speech recognition engine that allows recognition to
input once recognition waiting has begun.

It would seem reasonable to me that for Speech Recognition, if a barge
*true* is followed by a barge in *false* prompt, that the *false* (and
subsequent false settings) would be ignored by the speech recognition
the next transition state.

I see no problem for the reverse condition. If the first prompt is barge
*false*, then just play the prompt without starting recognition. Only
when a
barge in *true* prompt is encountered is the recognition waiting

CR16-1 Resolution: rejected 

It is possible to implement *true* to *false* bargein by re-starting
recognition. We realize this may not be the perfect solution, but we are
reluctant to change it at this stage in the standards process. A future
version of the language may provide a better solution. 


Issue CR18-1
Is there really no way to specify a URI for an external SSML file in
VXML 2.0?
I am looking for an "src=" attribute of the <prompt> element that could
specify resources whose mime types are either "application/ssml+xml" or
"text/plain". This would be analogous to the "src=" attribute of the
<grammar> element that takes a URI specifying a resource whose mime type
"application/srgs+xml" or "application/srgs". Currently it appears that
Speech markup must be in line.

Am I missing something?

CR18-1 Resolution: rejected 

The specification doesn't provide a mechanism to reference external SSML
documents. This will be considered for a future version of the language.
