Method for analyzing fundamental frequency information and voice conversion method and system implementing said analysis method

摘要

A method for analyzing fundamental frequency information contained in voice samples includes at least one analysis step ( 2 ) for the voice samples which are grouped together in frames in order to obtain information relating to the spectrum and information relating to the fundamental frequency for each sample frame; a step ( 20 ) for the determination of a model representing the common characteristics of the spectrum and fundamental frequency of all samples; and a step ( 30 ) for determination of a fundamental frequency prediction function exclusively according to spectrum-related in formation on the basis of the model and voice samples.
