Résumé

The Son – Discours project proposes a multi-level analysis of spoken language at the interface of linguistics and computer science. The goal is to study linguistic variation: (a) at the fine-scale level of sound structure (phonetic and phonological variation); (b) at the larger scale of discourse (variation in the organization of discourse). The working hypothesis is that language is variable, but variation is not random. Variable patterns develop within the context of a linguistic system which is both flexible and constraining. Some patterns may remain circumscribed to the system and disappear, others may evolve by moving further away from the system, leading to a linguistic change. Understanding how variation emerges, and what factors may favor or constrain it, is the general goal of our project. We propose a hybrid methodology, where the hypothesis is tested by both behavioral experimental methods and automatic classification techniques borrowed from automatic speech recognition, in joint, incremental approaches combining linguistic analysis and automatic processing. We use machine learning methods derived from data mining to test the likelihood that a given variation pattern may be related to linguistic change.
