Abstract
A method and apparatus for speech synthesis in a computer-user interface using random paralinguistic variation is described herein. According to one aspect of the present invention, a method for synthesizing speech comprises generating synthesized speech having certain prosodic features. The synthesized speech is further processed by applying a random paralinguistic variation to the acoustic sequence representing the synthesized speech without altering the linguistic prosodic features. According to one aspect of the present invention, the application of the paralinguistic variation is correlated with a previously applied paralinguistic variation to reflect a gradual change in the computer voice, while still maintaining a random quality.
