I think this issue is more related to speech recognition servers than to

It can be achieved by adding additional platform specific built-in types in
system and reference them using VoiceXML. So It may not be required to add a
additional built-in type. It would be even harder to come up with a correct
built-in grammar given that these phonetic alphabet may not be popularly
used as an standard by everyone.

A platform specific built-in type grammar which could support such a thing
could easily treat the result as if it was uttered properly. I think most
speech recognition engine have support for implementing it.

Subject: ASR without underlying grammar?


as far as I understood the specification, there is no possibility to have
ASR without specifying an active grammar in VoiceXML. What if the author
cannot provide a grammar, in cases where the input can't be constrained?
(e.g. when giving proper names) Does VoiceXML deal with that problem?
As a solution, the user could spell the name out, using a built-in grammar
for a phonetic alphabet ("Andrew, Benjamin, Charlie" etc., or anything
equivalent for a specific language), and the Voice Browser could
nevertheless treat the result as if it was uttered properly.
