Abstract : The work presented in this thesis lies within the scope of prosody conversion and more particularly the fundamental frequency conversion which is considered as a prominent factor in prosody processing. This document deals with the different steps necessary to build such a conversion system : stylization, clustering and conversion of melodic contours. For each step, we propose a methodology that takes into account the issues and difficulties encountered in the previous one. A B-spline based approach is first proposed to model the melodic contours. Then to represent the melodic space of a speaker, a HMM based approach is introduced. To finish, a prosody transformation methodology using non-parallel corpora based on a speaker adaptation technique is derived. The results we obtain tend to show that it is necessary to model the evolution of the melody and to drive the transformation system by using morpho-syntactic information.
