Bear, J., Dowding, J., & Shriberg, E. (1992, June). Integrating multiple knowledge sources for detection and correction of repairs in human-computer dialog. In 30th Annual Meeting of the Association for Computational Linguistics (pp. 56-63).
We have analyzed 607 sentences of spontaneous human-computer speech data containing repairs, drawn from a total corpus of 10,718 sentences. We present here criteria and techniques for automatically detecting the presence of a repair, its location, and making the appropriate correction. The criteria involve integration of knowledge from several sources: pattern matching, syntactic and semantic analysis, and acoustics.
