Private speech in children has been suggested to be associated with their self-regulation for their current task. Although studies also suggested that autistic children engage in private speech that did not have any function in their task solving behavior, we investigated about its function for the children's behavior during their play. We observed videos of autistic children playing alone in a room inside their home. The parents were asked to record the video. Our points of observation were (1) timings of repeated utterances in the child's sequence of behaviors, (2) moves of the vocal pitch, and (3) consistency of its situation-vocal pattern link during the videos. The results suggested that there seemed to be individually unique sound patterns repeated in similar situations.
