Short term usage scenario
A voice application pushes information (E.g. a list of flights) to the caller’s device one or more times during a conversation
Achievable using WAP “push”, but requires phones that allow concurrent voice/data
Needs to be easy for the content developer to synchronize the two applications
Nuance has a working demo of this using the web, not WAP (www.v-commerce.com)
Voice handoff to WAP
The voice application “links” or “transfers” to a WML page, putting the user in WAP mode
WAP handoff to Voice
Essentially, placing a call to a SIP URL
WAP makes use of networked speech
Use networked ASR to enter some information; WAP interaction continues
Fully synchronized WAP and Voice
User says “the second one” or taps
Shorter term
Allow voice applications to push visual content to clients (once 3G networks arrive)
Enable a unified authoring experience for the content developer writing WML and VoiceXML
Longer term
Agree on means for WML content to link to a SIP URL
Agree on means for a SIP session to “transfer” the caller to a WML URL
User interface standards
How to signal voice<->WAP transitions
When to confirm using voice vs. WAP
How to let the user choose and switch modalities
