Gémellité et reconnaissance automatique du locuteur

Abstract : This paper presents a speaker recognition system applied to a limited corpus of twin speakers. Two experiments are carried out using the LIA speaker recognition platform AMIRAL. The aim of the first experiment is to identify a twin of a speaker among a corpus, whereas the second one is a classical speaker verification task. The results show that an automatic system is generally able to identify a twin with an acceptable performance (85 % of good identification). Furthermore, the system is still able to discriminate the target speaker from its twin. For the verification experiment, we obtain 6% F.A. for 0% F.R. and 53% F.R. for 0% F.A.. As the available amount of data is extremely limited, results have to be interpreted with caution.
