VOICE PROCESSING SYSTEM

摘要

PROBLEM TO BE SOLVED: To cope with latently countless different types of feelings in text voice synthesis.SOLUTION: A text voice synthesis method comprises: receiving an input text; dividing the input text into sequences in acoustic units; converting the sequences in acoustic units into sequences of voice vectors by using an acoustic model (where the above mentioned model includes a plurality of models/parameters describing probability distribution for associating acoustic units with voice vectors); and outputting the sequences of voice vectors as a voice. This method comprises: extracting expression characteristics from the input text for generating expression language feature vectors to be constituted in a first space; and determining at least a part of the models/parameters by mapping the expression language feature vectors on expression synthesis feature vectors to be constituted in a second space.
