Abstract
Abstract A method and apparatus for the automatic application of vocal emotion parameters to text in a text-to-speech system. Predefining vocal parameters for various vocal emotions allows simple selection and application of vocal emotions to text to be output from a text-to-speech system. Further, the present invention is capable of generating vocal emotion with the limited prosodic controls available in a concatenative synthesizer.
