During an interaction people are known to mutually adapt. Phonetic adaptation has been studied notably for prosodic parameters such as loudness, speech rate or fundamental frequency. In most of the cases, results are contradictory and the effectiveness of phonetic convergence during an interaction remains an open issue. This paper describes an experiment based on a children game known as speech dominoes that enabled us to collect several hundreds of syllables uttered by different speakers in different conditions: alone before any interaction vs. after it, in a mediated interaction vs. in a face-to-face interaction. Speech recognition techniques were then applied to globally characterize a possible phonetic convergence.
