VOICE RESPONSE SYSTEM

摘要

With interactive voice response services, it can be frustrating for a user to become stuck in a dialogue where the same question is asked repetitively. In this invention the wording of questions used by the system are varied throughout a dialogue depending upon how many times a user has visited a dialogue state ever in their call history. Furthermore the wording of the question is also varied in dependence upon the way in which the question was asked the last time the user was in a particular dialogue state.
