Title: Method of detecting voice activity of signal and voice signal coder including device for implementing this method
Inventor: GASS RAYMOND
IPC: G10L25/78
Filed: 2002-06-10
Abstract: PROBLEM TO BE SOLVED: To provide an effective voice detection method, which protects the validity of audio activity detection and does not damage the signal quality after decoding, and to provide a voice signal coder including a device which implements this method. SOLUTION: This method smoothes the decision of 'voice' or 'noise' to realize voice activity detection of a signal, and avoids loss of conversation segments. This method is especially adapted to cases of high noise level. This method gives priority to comprehensibility of a reproduced signal after decoding in contrast to a known method which gives priority to traffic optimization. An encoded signal is divided into a plurality of frames, and each signal frame is determined as 'voice' or 'noise'. When the signal energy is increased in a frame preceding the current frame, the current frame is determined as 'voice' even when it is increased only a little; and the current frame is determined as 'noise' only when the characteristics of the signal correspond to noise characteristics in at least i following frames (for example, i=6). This method is applied to telephone communications.
