Abstract: Statistical parametric speech synthesis based on HMMs has grown in popularity over the last years. In this talk, its system architecture is outlined, and then basic techniques used in the system, including algorithms for speech parameter generation from HMM, are described with simple examples. Relation to the unit selection approach and recent improvements are summarized. Techniques developed for increasing the flexibility and improving the speech quality are also reviewed.
