A plurality of microphone signals can be obtained. In the plurality of microphone signals, speech of a user can be detected. A gaze of a user can be determined based on the plurality of microphone signals. A voice activated response of the computing device can be performed in response to the gaze of the user being directed at the computing device. Other aspects are described and claimed.

Voice trigger based on acoustic space

A plurality of microphone signals of a microphone array may be obtained. An environment change may be detected based on the microphone signals. In response, a reverberation time environment may be determined. The reverberation may be used to modify a playback audio signal.

Logic for reverberation time estimation

Acoustic pickup beams (sound beams) can be formed in a physical environment from a plurality of microphone signals. Each of the sound beams can measure acoustic energy in a direction of the respective sound beam. Directional decay of the acoustic energy measured through each of the sound beams is determined. Room surface acoustic properties of the physical environment are determined based on mapping the directional decay of the acoustic energy to the physical environment. Other aspects are described and claimed.
