This paper describes our work on building aformant synthesis system based on both rule generated and database driven methods. Three parametric synthesis systems are discussed: our traditional rule based system, a speaker adapted system, and finally a gesture system.The gesture system is a further development of the adapted system in that it includes concatenated formant gestures from a data-driven unit library. The systems are evaluated technically, comparing the formant tracks with an analysed test corpus. The gesture system results in a 25% error reduction in the formant frequencies due to the inclusion of the stored gestures. Finally, a perceptual evaluation shows a clear advantage in naturalness for the gesture system compared to both the traditional system and the speaker adapted system.
