1. A method, performed by a computing device, comprising:
obtaining a plurality of microphone signals generated from a plurality of microphones;
detecting, in the plurality of microphone signals, speech of a user;
determining whether the speech is originating in a shared acoustic space with the computing device based on the plurality of microphone signals;
determining an acoustic gaze of the user based on the plurality of microphone signals, wherein the acoustic gaze comprises a direction in which a head and mouth of the user is pointing with respect to the computing device; and
triggering a voice activated response of the computing device in response to a determination that the speech originates in the shared acoustic space with the computing device and the acoustic gaze of the user being directed at the computing device.
