I’ve posted a new tutorial showing my take on the “Confidence-Based Confirmation” technique first outlined by Matt Oshry of TellMe networks. This example uses a VoiceXML subdialog approach to confirm caller utterances, and also leverages the new functionality provided by the VoiceXML 2.1 specification to record caller input while performing a recognition. This approach is critical to the use of VoiceXML in telephone-based voting systems. A complete overview and sample code are provided.
