1. A smartphone, comprising:

  • a microphone;

    a radar system, implemented at least partially in hardware, configured to;

    provide a radar field;

    sense reflections from an object in the radar field;

    analyze the reflections from the object in the radar field; and

    provide, based on the analysis of the reflections, radar data;

    one or more computer processors; and

    one or more computer-readable media having instructions stored thereon that, responsive to execution by the one or more computer processors, implement a radar-based application configured to;

    maintain the microphone in a non-operational mode;

    detect, based on the radar data, a gesture by the object in the radar field;

    determine, based on the radar data, that the gesture is a voice input trigger; and

    responsive to determining the gesture is the voice input trigger, cause the microphone to enter an operational mode.
