In expressive speech synthesis, a key challenge is the generation of flexibly varying expressive tone while maintaining the high quality achieved with unit selection speech synthesis methods. Existing approaches have either concentrated on achieving high synthesis quality with no flexibility, or they have aimed at parametric models, requiring the use of parametric synthesis technologies such as diphone, formant or HMM-based synthesis.
