Abstract
A voice activity detector () includes a frame divider () for dividing frames of an input signal into consecutive sub-frames, an energy level estimator () for estimating an energy level of the input signal in each of the consecutive sub-frames, a noise eliminator () for analyzing the estimated energy levels of sets of the sub-frames to detect and eliminate from enhancement noise sub-frames and to indicate remaining sub-frames as speech sub-frames, and an energy level enhancer () for enhancing the estimated energy level for each of the indicated speech sub-frames by an amount which relates to a detected change of the estimated energy level for a current speech sub-frame relative to that for neighboring speech sub-frames.
