Abstract
Methods and systems for cancelation of table noise in a speaker system used for video or audio conferencing are disclosed. Table noise is cancelled in one embodiment by providing a signal or a message whenever a key is depressed on a keyboard or a mouse is clicked. When the key depression signal or message is received, the system evaluates whether speech is occurring. If speech is not occurring, then the microphone in the system is muted. However, if speech is occurring, the microphone is not muted for a period of time to allow the speech to be transmitted to the far end. This allows the conference to be continued in the presence of keyboard sounds if speech is occurring at the same time but also silences the keyboard sounds if speech is not occurring.
