Abstract
A wizard that from a fixed design can create various audio interfaces. The generated interfaces can be speech only, DTMF only, or various mixed speech and DTMF UIs. When specifying both speech and DTMF prompts, a number of combinations of these interfaces could be automatically generated. Robust speech recognition systems can be built by automatically generating a “shadow” DTMF application. The DTMF application will perform the same task as the primary speech application; however the transfer to a DTMF application could be done explicitly by the user, or could be transferred automatically (either a temporary or permanent transition) at a point in the call flow where there was a problem with the speech recognition.
