Factor analysis models representing various voice characteristics for HMM based speech synthesis

Abstract (in Japanese) (See Japanese page) 
(in English) This paper describes factor analysis models for realizing
various voice characteristics in the HMM-based speech synthesis. The
eigenvoice method can synthesize speech with arbitrary voice
characteristics by interpolating representative HMM sets. However, the
objective of PCA is to accurately reconstruct each speaker-dependent
HMM set, and this is not equivalent to estimating models which
represent training data accurately. To overcome this problem, we
propose a general speech model which generates speech utterances with
various voice characteristics directly. In the proposed method, the
HMM states, factors representing voice characteristics and contextual
decision trees are simultaneously optimized within a unified framework.
