xml-dev - VoiceXML inputs

[Oliver Becker <obecker@informatik.hu-berlin.de>]

Hello,

is there anybody out there being familiar with VoiceXML [1] ?
The problem I couldn't figure out so far is how to express the
counterpart of HTML's <input type="text">

I.e. the user enters (speaks) something unknown and this input will
be submitted to a server for further processing. The problem is:
VoiceXML's field element requires a type attribute wich specify a
grammar. In this case I don't have a grammar - I don't know 
possible answers in advance.

Is this an issue that the spec doesn't address or do I missing something?
Or is it just not possible with IBM/alphaWorks' implementation [2] ?

Regards,
Oliver
