Evolution d'une société artificielle d'agents de parole : un modèle pour l'émergence des structures phonétiques

Abstract : The origins and evolution of language are still clouded in mystery. The work presented in this thesis was done in the framework of the quest for universal characteristics in the phonological structure of world's languages. Emergent aspects of phonetic systems are explored. An approach is discussed that aims, first, at modelling the formation of phonetic inventories by investigating the basic mechanisms of the interaction between speakers and listeners and, second, at relating those mechanisms to the emergence of sound systems. A model of vocalic perceptual exchanges in a society of speech agents is presented, along with simulation results of two different studies. The first one concerns predictions of vocalic systems with small number of items. The predictions obtained are in accordance with the statistics of world's languages. In the second set of simulations, we explore the role of the principle of "Maximum Use of Available distinctive Features (MUAF)" in structuring phonetic inventories. This principle is invoked to explain why languages with crowded vowel inventories tend to use additional phonetic features.
