This phenomenon, known in the literature as entrainment, alignment, accommodation, or adaptation has been found to occur along many acoustic, prosodic, syntactic and lexical dimensions in both human-human interactions (Brennan and Clark, 1996;Coulston et al., 2002;Reitter et al., 2006;Ward and Litman, 2007;Niederhoffer and Pennebaker, 2002;Ward and Mamidipally, 2008;Buder et al., 2010) and humancomputer interactions (Brennan, 1996;Bell et al., 2000;Stoyanchev and Stent, 2009;Bell et al., 2003) and has been associated with dialogue success and naturalness (Pickering and Garrod, 2004;Goleman, 2006;Nenkova et al., 2008).
interlocutors who entrain achieve better communication.
