METHOD AND DEVICE FOR RECOGNIZING LANGUAGE SEGMENTS IN LANGUAGE SIGNAL PROCESSING

摘要

A method and apparatus for detecting speech segments of a speech signal processing device. A critical band is divided into a certain number of regions according to the frequency characteristics of noise, sets an adaptive signal threshold and an adaptive noise threshold by region of each frame, and determines whether each frame is a speech segment or noise segment by comparing the log energy calculated by region of each frame and the signal threshold and noise threshold set by region. Thus, a speech segment can be detected rapidly and accurately by using a small number of operations even in a noise environment.
