AUTOMATED SPEECH RECOGNITION PROXY SYSTEM FOR NATURAL LANGUAGE UNDERSTANDING

摘要

PROBLEM TO BE SOLVED: To provide an interactive system that provides a consistently high-quality experience without limitations of constituent ASR components.SOLUTION: An interactive response system mixes HSR subsystems with ASR subsystems to facilitate overall capability of voice user interfaces. The system permits imperfect ASR subsystems to nonetheless relieve burden on HSR subsystems. An ASR proxy is used to implement an IVR system, and the proxy dynamically determines how many ASR and HSR subsystems are to perform recognition for any particular utterance, based on factors such as confidence thresholds of the ASRs and availability of human resources for HSRs.
