Abstract (in Japanese) (See Japanese page) 
(in English) This paper presents a speaker recognition technique based on log-linear models (LLMs) using Bayesian statistics. Since discriminative models can use various features in the unified framework, preparation of features that are useful for classification is an important problem. Statistics obtained from Gaussian Mixture Models (GMMs) trained by the maximum likelihood method or the maximum a posteriori method are recently used as features for speaker recognition. However, these training methods often occur the over-fitting problem. In this paper, the Bayesian approach is applied to train GMMs and statistics of GMMs in the Bayesian approach are used as features of LLMs. Experimental results show that the proposed LLM-based method significantly improved the identification rates from conventional GMM-based methods.
