A computing device may receive an indication of an audio signal captured by a microphone, wherein the audio signal includes voice input. The computing device may determine that the voice input in the audio signal is from an authorized user of the computing device and includes a trigger phrase associated with a request to trigger device finder functionality based at least in part on comparing the voice input with data provided by the authorized user of the computing device. The computing device may, in response to determining that the voice input in the audio signal is from the authorized user of the computing device and includes the trigger phrase associated with the request to trigger device finder functionality, cause a speaker of the computing device to audibly output the alert sound to assist the authorized user to locate the computing device.
