The W3C Voice Browser Working Group has posted the last call working draft of VoiceXML 2.1 recommendation.
VoiceXML is used to describe those annoying call trees you hear
when calling most major companies.
(Press 1 if you want to wait on hold for 20 minutes and then be hung up on;
press 2 if you want to wait indefinitely; press 3 if you'd rather we just hung up on you now.)
New features in 2.1 include
data and foreach elements, dynamic
grammars and scripts,
detecting barge-in during prompt playback,
fetching xml without requiring a dialog transition, recording user utterances while attempting recognition, and specifying the media format of utterance recordings.
