Abstract: Certain aspects of the present disclosure provide a voice-controlled system for controlling devices and systems in a surgical setting. The voice-controlled system includes at least one microphone and at least one loudspeaker distributed within the surgical setting to receive and audibly respond to voice commands from operating staff. In certain aspects, the at least one microphone and at least one loudspeaker include a phased microphone array and a phased loudspeaker array that are coordinated and synchronized to perform active noise reduction, echo cancellation, and directional determination of sound sources. The voice-controlled system performs tasks, such as activation of surgical devices, based on verbal interactions with the operating staff through the at least one microphone and at least one loudspeaker. In certain aspects, the voice-controlled system is configured to recognize, decipher, and prioritize natural language commands from different operating staff, and further provides pre-programming of device settings and operating staff pre-sets.
