Abstract
Disclosed is a method capable of adaptively aligning windows to extract features according to the types and characteristics of voice signals. To this end, window lengths based on the widow update points in a corresponding order are determined by employing the concept of a higher order peak, and windows are aligned according to window lengths. When the windows are aligned according to such a manner, the start and end points of each window is known, so that it becomes possible to easily extract and analyze peak feature information.
Claims15
A system for aligning a window to extract a peak feature of a voice signal, the system comprising:
- a peak information extraction unit for extracting peak information from a received voice signal;
- an update point determination unit for determining a window update point using the peak information;
- a window length determination unit for determining a window length by shifting a window based on the update point;
- a window alignment unit for aligning a window according to the determined window length;
- and
- a window analysis unit for performing window analysis for feature extraction by detecting start and end points of the window from the aligned window.
