Simultaneous Modelling of Acoustic, Phonetic, Speaker Features Using Improved Three-Way Restricted Boltzmann Machine

Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, we argue the way of modelling speech signals using improved three-way restricted Boltzmann machine (3WRBM) where acoustic features, latent phonological features, and speaker-identity features are considered. The 3WRBM is an energy-based probabilistic model that includes three kinds of potentials: unary potentials of each variable, pairwise potentials of every two variables, and three-way potentials of the three variables. In our approach, we design the three-way potentials properly in the speaker-adaptive training (SAT) manner. The optimized model captures the relationships between the variables, enables to compute conditional probabilities of each variables, and is appliable to many tasks in speech signal processing. For example, estimating speaker-identity features given acoustic features is used for speaker recognition. Another example is estimating acoustic features from the phonological features that are estimated given source speaker's acoustic features and the desired speaker-identity features; that is voice conversion. In our experiments, we evaluate the effectiveness of the speech modelling through a voice conversion task and a speaker recognition task.
