In this paper, we investigate the differences between human-directed speech and robot-directed speech during spontaneous human-human-robot interactions. The interactions under study are different from previous studies, in the sense that the robot has a more similar role as the human interlocutors, which leads to more spontaneous turn-taking. 20 conversations were extracted from a multi-party human-robot discussion corpus, where two humans are playing a collaborative card game with a social robot. Each utterance in the conversations was manually labeled according to addressee (robot or human). The following acoustic features were extracted: fundamental frequency, intensity, speaking rate, and total utterance duration. There were significant differences between human- and robot-directed speech for speaking rate and the total utterance duration. These results are in line with previous studies on robot-directed speech, and confirms that this difference holds also when the conversations are of a more spontaneous nature.
