Abstract | |||||||||||||||
| One of the ways in which gesture supplements communication is by helping to identify the “meta-data ” that comprises the organizational structure of the discourse. One such type of meta-data is sentence unit boundaries;the detection of sentence boundaries in informal, spontaneous speech is a difficult problem. In this abstract, we explore whether gestural cues can improve sentence boundary detection. We have hand-annotated a corpus of 26 short videos of spontaneous speech and gesture (see [1] for a more complete account of this research). We employ the movement phase and gesture phrase taxonomies as summarized by McNeill [2]. These gesture features correlate well with sentence boundaries in this corpus. Table 1 shows the probabilities of various gesture features, conditioned on the presence of sentence boundary events. | |||||||||||||||
