GENERATION OF SYNTHETIC SPEECH

摘要

There is disclosed a method of generating synthetic speech sound data relating to first and second utterances. Interpolation between or extrapolation from first and second sets of parameters encoding said utterances results in a third set of parameters used to synthesise the synthetic speech sound. Each set of parameters preferably includes separate source parameters and spectral parameters derived using linear prediction coding. Related methods of trailing and diagnosis, and related apparatus are also disclosed.
