Abstract
A multi-rotor remote control aircraft for capturing audio and/or video signals and a method for remote controlling the aircraft by way of voice commands. The aircraft and method mitigate the effects of audio noise produced by motors and propellers on reception and detection of the voice commands. Audio acquisition components are provided for receiving the voice commands while noise acquisition components are devoted for capturing the environmental noise. The mitigation of the noise effects is achieved by filtering and a cancellation technique. With the cancellation technique, the noise part contained in the signal captured by the noise acquisition components is equalized to the noise part contained in an audio signal carrying the voice commands and then it is subtracted from the audio signal.
