ABSTRACT:
Provided is a voice signal detection system and method, which extracts peaks from an input signal, compares a voltage level of each of the extracted peaks to a pre-set threshold voltage level, converts the comparison result to a binary sequence, determines the length of a test window to examine the converted binary sequence, detects micro events in a test window length unit, links the detected micro events, and determines a starting and ending point of a voice signal by detecting a starting and ending point of the linked micro events. Accordingly, by extracting and analyzing peak characteristic information of a time axis, voice can be detected with minimal calculation and noise interference.
