VOICE ACTIVITY DETECTION/SILENCE SUPPRESSION SYSTEM

摘要

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.

主权项

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 on the spectrum constancy criterion and determining that the energy associated with the communication channel has changed, the activating of silence suppression comprising associating communication energy with the communication channel that was not already associated with the communication channel prior to activating silence suppression.
