METHOD FOR ANALYZING FUNDAMENTAL FREQUENCY INFORMATION AND VOICE CONVERSION METHOD AND SYSTEM IMPLEMENTING SAID ANALYSIS METHOD

摘要

Method for analyzing fundamental frequency information contained in voice samples, characterized in that it comprises at least: - a step (2) of analyzing voice samples gathered in frames in order to obtain, for each frame of samples, information relating to the spectrum and information relating to the fundamental frequency; - a step (20) of determining a model representing the common characteristics of the spectrum and of the fundamental frequency of all the samples; - a step (30) of determining, on the basis of this model and voice samples, a fundamental frequency prediction function solely as a function of information relating to the spectrum.
