Abstract
An interactive response system directs input to a software-based router, which is able to intelligently respond to the input by drawing on a combination of human agents, advanced speech recognition and expert systems. The system utilizes human “intent analysts” for purposes of interpreting customer utterance. Automated speech recognition subsystems are trained by coupling utterances with IA-selected meanings for those utterances, using non-real time systems to develop the training information for the automated speech recognition subsystems.
