Abstract
The emotion is to be added to the synthesized speech as the prosodic feature of the language is maintained. In a speech synthesis device, a language processorgenerates a string of pronunciation marks from the text, and a prosodic data generating unitcreates prosodic data, expressing the time duration, pitch, sound volume or the like parameters of phonemes, based on the string of pronunciation marks. A constraint information generating unitis fed with the prosodic data and with the string of pronunciation marks to generate the constraint information which limits the changes in the parameters to add the so generated constraint information to the prosodic data. A emotion filter, fed with the prosodic data, to which has been added the constraint information, changes the parameters of the prosodic data, within the constraint, responsive to the feeling state information, imparted to it. A waveform generating unitsynthesizes the speech waveform based on the prosodic data the parameters of which have been changed.
