Abstract:

How did culturally shared systems of combinatorial speech sounds initially appear in human evolution? This paper proposes the hypothesis that their bootstrapping may have happened rather easily if one assumes an individual capacity for vocal replication, and thanks to self-organization in the neural coupling of vocal modalities and in the coupling of babbling individuals. This hypothesis is embodied in agent-based computational experiments, that allow to show that crucial phenomena, including structural regularities and diversity of sound systems, can only be accounted if speech is considered as a complex adaptive system. Thus, the second objective of this paper is to show that integrative computational approaches, even if speculative in certain respects, might be key in the understanding of speech and its evolution.

Presenter:

Pierre-Yves Oudeyer is researcher at the Sony Computer Science Laboratory in Paris where he co-founded and heads the Developmental Robotics group. He is also a member of the Origins of Language group at Sony CSL, and teaches Social and Cognitive Robotics at Ecole Nationale Supérieure des Techniques Avancées. He studied theoretical computer science at Ecole Normale Supérieure de Lyon, and received his PhD in artificial intelligence from University Paris VI. He is interested in the mechanisms that allow humans and robots to develop perceptual, motivational, behavioral and social capabilities to become capable of sharing cultural representations and of natural embodied interaction. In particular, he uses robots to study how new linguistic conventions can be established in a society of individuals, and has developed numerous computational models of the interactions between self-organization, learning and selection in the evolution of language. He also works on sensorimotor development and self-motivation, and his group built one of the first robots endowed with artificial curiosity. He participated in the development of emotional speech synthesis for the Sony Qrio humanoid robot. He was co-chair of the Epigenetic Robotics international conference, and is associate editor of Frontiers in Neurorobotics. He is expert and reviewer in cognitive robotics and speech technologies for the European Commission as well as for the French National Research Agency (ANR). He has published a book, more than 50 papers in international journals and conferences, and holds 8 patents on technologies such as emotional speech synthesis and recognition, active learning, and human interaction with autonomous robots. He received several prizes for his research on the origins of speech and developmental systems, including the prize “Le Monde de la recherche universitaire”. WebSite: http://www.csl.sony.fr/~py/
