On Laughter and Speech-Laugh, Based on Observations of Child-Robot\n Interaction

摘要

In this article, we study laughter found in child-robot interaction where it\nhad not been prompted intentionally. Different types of laughter and\nspeech-laugh are annotated and processed. In a descriptive part, we report on\nthe position of laughter and speech-laugh in syntax and dialogue structure, and\non communicative functions. In a second part, we report on automatic\nclassification performance and on acoustic characteristics, based on extensive\nfeature selection procedures.\n
