Pronunciation normally varies in spontaneous speech, and is an integral aspect of spontaneous expression. This study describes a voice transformation-based approach to generating spontaneous speech with syllable contractions for Hidden Markov Model (HMM)-based speech synthesis. A multi-dimensional linear regression model is adopted as the context-dependent, state-based transformation function to convert...
In this paper, a novel hierarchical prosodic unit selection method is proposed based on pitch contour pattern retrieval, in order to obtained natural pitch contour of the personalized synthetic voice. In this framework, a hierarchical prosodic unit based on Fujisaki model is used to take local pitch contour variation and global intonation of utterance into account. Furthermore, novel ways of integrating...
A novel approach is proposed to creating a polyglot speech synthesis system without the need of collecting speech data from a bilingual (or multilingual) speaker, which is often expensive or even infeasible. Given a target speaker with data in the first language (Mandarin in this study), the basic idea is to construct artificial utterances in the second language (English) via selection of speech sample...
