A Multiclass framework for Speaker Verification within an Acoustic Event Sequence system

Résumé

Building acoustic events and their sequence analysis (AES system) is a method that proved its efficiency in [1]. Indeed, the methodology combines the power of the world model GMM, used in state-of-the-art speaker detection systems, for extracting speaker independent events with an analysis of these event sequences via tools usually used in so-called High Level Speaker Detection systems. The efficiency of this system has been validated at the last NIST evaluation campaign. This paper aims at proposing a new framework by applying an AES system on multiple classes, C-AES. The originality of this work is to consider that intraclass sequence analysis can bring more information than a global analysis on the whole speaker utterance. This paper also proposes a method to take into account the apriori knowledge of the classes within the scoring process. The results support the fact that intraclass information is discriminant for speaker verification, as a combination with a state-of-the-art GMM brings a 12% relative gain at the DCF.
