One line of work on turn-taking in dialogue suggests that speakers react to “cues” or “signals” in the behaviour of the preceding speaker. This paper describes a perception experiment that investigates if such potential turn-taking cues affect the judgments made by non-participating listeners. The experiment was designed as a game where the task was to listen to dialogues and guess the outcome, whether there will be a speaker change or not, whenever the recording was halted. Human-human dialogues as well as dialogues where one of the human voices was replaced by a synthetic voice were used. The results show that simultaneous turn-regulating cues have a reinforcing effect on the listeners’ judgements. The more turn-holding cues, the faster the reaction time, suggesting that the subjects were more confident in their judgments. Moreover, the more cues, regardless if turn-holding or turn-yielding, the higher the agreement among subjects on the predicted outcome. For the re-synthesized voice, responses were made significantly slower; however, the judgments show that the turn-taking cues were interpreted as having similar functions as for the original human voice.
