Shriberg, Elizabeth & Bear, John & Dowding, John. (2004). Automatic Detection and Correction of Repairs in Human-Computer Dialog. 10.3115/1075527.1075628.
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.
