Abstract
Official abstract text for this publication.
A Voice Activity Detection/Silence Suppression (VAD/SS) system is connected to a channel of a transmission pipe. The channel provides a pathway for the transmission of energy. A method for operating a VAD/SS system includes detecting the energy on the channel, and activating or suppressing activation of the VAD/SS system depending upon the nature of the energy detected on the channel.
First claim
Opening claim text (preview).
1 . A method of controlling communication, the method comprising: detecting, using a processing device, a change in energy associated with a communication channel; determining, using the processing device, whether noise energy associated with the communication channel has changed based on a spectrum constancy criterion; and activating silence suppression, using the processing device, in response to determining that the noise energy associated with the communication channel has changed based…
