A method for segregation of speech signals.
Résumé
This paper deals with the problem of blind separation of under-determined or over-completes mixtures (i.e. more sources than sensor) and more particularly in the special case of two speech signals and one sensor. After a introduction to the problem of blind separation of sources, an algorithm based on time-frequency representations (TFR) is presented. Finally, some experiments are conducted and some experimental results are given.
