Abstract
In a method for performing a segmentation operation upon a synthesizing speech signal and an input speech signal, a synthesized speech signal and a speech element duration signal are generated from the synthesizing speech signal A first feature parameter is extracted from the synthesized speech signal, and a second feature parameter is extracted from the input speech signal. A dynamic programming matching operation is performed upon the second feature parameter with reference to the first feature parameter and the speech element duration signal to obtain segmentation points of the input speech signal.
Claims16
A method for performing a segmentation operation upon a synthesizing speech signal and an input speech signal, comprising the steps of:
- generating a synthesized speech signal and a speech element duration signal from said synthesizing speech signal;
- extracting a first feature parameter from said synthesized speech signal;
- extracting a second feature parameter from said input speech signal;
- and
- performing a dynamic programming matching operation upon said second feature parameter with reference to said first feature parameter and said speech element duration signal to obtain segmentation points of said input speech signal.
An apparatus for performing a segmentation operation upon a synthesizing speech signal and an input speech signal, comprising:
- a speech synthesizing unit for generating a synthesized speech signal and a speech element duration signal from said synthesizing speech signal;
- a feature parameter extracting unit for extracting a first feature parameter from said synthesized speech signal and extracting a second feature parameter from said input speech signal;
- and
- a matching unit for performing a dynamic programming matching operation upon said second feature parameter with reference to said first feature parameter and said speech element duration signal to obtain segmentation points of said input speech signal.
