USING FINITE STATE GRAMMARS TO VARY OUTPUT GENERATED BY A TEXT-TO-SPEECH SYSTEM |
摘要 |
The present invention discloses a text-to-speech system that provides output variability. The system can include a finite state grammar, a variability engine and a text-to-speech engine. The finite state grammar can contain a phrase role consisting of one or more phrase elements. The phrase rule can deterministically generate a variable text phrase based upon at least one random number. The phrase rule can include a definition for each of the phrase elements. Each definition can be associated with at least one defined text string. The variability engine can construct a random text phrase responsive to receiving an action command, wherein said finite state grammar is used to create the text phrase. The variability engine can also rely on user-specified weights to adjust the output probabilities. The speech-to-text engine can convert the text phrase generated by the variability engine into speech output.
