Observations on overlap: findings and implications for automatic processing of multi-party conversation |
Abstract | ||

We examine the distribution of overlapping speech in different corpora of natural multi-party conversations, including two types of meetings, and two corpora of telephone conversations. Analyses are based on forced alignment and speech recognition using an identical recognizer across tasks. Three results are discussed. First, all corpora show high overall rates of overlap, with similar rates for meetings and teleph one conver- sations. Second, speech recognition performance in non-overlapped re- gions of meetings is no worse than that in single-channel telephone con- versations, while recognition in overlap regions degrades considerably. Finally, interrupt locations are associated with endpoint s of word-level events in a speaker's turn, including backchannels, discou rse markers, and disfluencies. Results suggest that overlap is an importa nt inherent characteristic of conversational speech that should not be ignored; on the contrary, it should be jointly modeled with acoustic and language model information in machine processing of conversation. |
