RE: MMI - how to handle async events in VXML and CCXML to sync GUI and VUI

Nicola,
  No, there is no way to interrupt a VoiceXML 2.1 application asynchronously.  We worked on this feature as part of VoiceXML 3, but that specification was never completed.  As things stand, you would have to add this feature to your platform as an extension.  If you want to see what we had in mind for VXML 3, look at section 6.13 of the preliminary draft at https://www.w3.org/TR/voicexml30/,  but be aware that this work was never completed and large parts of the document may well be nonsense.

Subject: MMI - how to handle async events in VXML and CCXML to sync GUI and VUI

Dear all

we know that is possible to use a <data> element in a VXML page to send a requesto to a ccxml page that throws an event, but how is possible to notify an async event to a VXML page/platform?

Suppose for example to have a multimodal application with two channgels, a GUI in HTML and a VUI in VXML, on the VXML side i have a prompt with a grammar and on the HTML side i have a form, if the form is submitted during the prompt, for a better user-experience it will be fine to stop the interaction on the VUI channel and reload a new VXML page with some updated information.

Is there any feature to handle this scenario?

With my best regards, Nicola.
