Research areas¶
The research activities in the proposed project are divided into four basic research areas (RA):
- RA1: Analysis of artifacts in synthetic speech
- RA2: Identification of relevant phonetic parameters crucial for the quality of synthetic speech
- RA3: Phonetically justified parameters for unit-selection and hybrid speech synthesis
- RA4: Automatic error prediction and dedicated signal modification
The estimated timing of each RA planned over the project lifetime, the workplace responsible for each objective, and the expected dissemination activities (publications) in terms of currently valid Results assessment methodology (in Czech) are summarized in the table.
