Method and apparatus for voice interaction over a network using parameterized interaction definitions

摘要

An audio browsing adjunct executes a voice markup language browser. The audio browsing adjunct receives a voice interactive request. Based on the request, the network node obtains a document. The document includes a voice markup, and a parameterized interaction definition or at least one link to a parameterized interaction definition when user interaction is required. The audio browsing adjunct interprets the document in accordance with the parameterized interaction definition. By using the parameterized interaction definition, entered data is typically verified at the audio browsing adjunct instead of at a network server. Further, the parameterized interaction definition can define a finite state machine. When it does, the parameterized interaction definition can be analyzed so that performance problems of the audio browsing adjunct are minimized.
