Abstract
Systems and methods may provide for monitoring an input audio signal from an onboard microphone of a mobile device while a host processor of the mobile device is in a standby mode. Additionally, a predetermined audio pattern may be identified in the input audio signal and a device location session may be triggered with respect to the mobile device based on the predetermined audio pattern. In one example, an output audio signal is generated during the device location session.
