“…Cues that regulate turn-taking. A number of authors have proposed that listeners project an upcoming end of a turn by using semantic, syntactic, prosodic, eye gaze, or body movement cues produced by the speaker (Bavelas, Chovil, Coates, & Roe, 1995;Beattie, 1979;Beattie, Cutler, & Pearson, 1982;Caspers, 1998Caspers, , 2003Clark & Fox Tree, 2002;Craig & Gallagher, 1982;Koiso, Horiuchi, Tutiya, Ichikawa, & Den, 1998;Miura, 1993;Robbins et al, 1978;Schaffer, 1983;Stephens & Beattie, 1986a, 1986bWells & MacFarlane, 1998; for reviews, see Ford &Thompson, 1996, andFox Tree, 2000). Conversely, a variety of devices have been proposed by which listeners can indicate their desire to take the turn, such as movements, audible inbreath, or interjected words (Bavelas et al, 1995;Dittmann & Llewellyn, 1968;Duncan & Niederehe, 1974;Harrigan, 1985;Thomas & Bull, 1981).…”
