Improvements in Czech Expressive Speech Synthesis in Limited Domain

Abstract

Abstract. In our recent work, a method on how to enumerate differences between various expressive categories (communicative functions) has been proposed. To improve the overall impact of this approach to both the quality of synthetic expressive speech and expressivity perception by listeners, a few modifications are suggested in this paper. The main ones consist in a different way of expressive data processing and penalty matrix calculation. A complex evaluation using listening tests and some auxiliary measures was performed.
