A multi-user voice control system for use in endoscopic imaging system includes a first input channel, a second input channel, an automatic speech recognizer (ASR), a control unit, and a selector. The first input channel receives speech of a first user, and the second input channel receives speech of a second user. The ASR recognizes speech received on the first channel and recognizes speech received on the second channel. The control unit enables the voice control system to control a device in the endoscopic imaging system in response to recognized speech. The selector selectively determines whether recognized speech associated with the first channel or recognized speech associated with the second channel is used to control the device, by applying a selection priority to the first and second channels.
