Czech audio-visual speech synthesis with an HMM-trained speech database and enhanced coarticulation

Original language description

The task of visual speech synthesis is usually solved by concatenation of basic speech units selected from a visual speech database. There are two main problems in this process. The first problem is a design of a database, that means estimation of the database parameters for all basic speech units. Second problem is a way how to concatenate selected basic phonetic units so as to eliminate the coarticulation effect. Both problems are aimed in our work, resulting in the Czech audio-visual speech synthesizer. We use HMM training process instead of some form of averaging for obtaining statistically best parameters for all basic phonetic units. For solution of a coarticulation effect we use the method of dominance functions.
