1. A wearable device comprising:

  • an air-based microphone;

    a bone conduction microphone; and

    logic, implemented at least partly in fixed-functionality hardware, to;

    determine a sound vibration condition of an ambient environment of the wearable device based at least in part on a signal associated with the air-based microphone,determine a motion condition of the wearable device based at least in part on a signal associated with the bone conduction microphone, andperform one or more of a plurality of automated voice operations based at least in part on the sound vibration condition and the motion condition, wherein the plurality of automated voice operations are to be arranged in order of progressively higher power domains,wherein one of the plurality of automated voice operations is a speaker verification operation that is to be activated based on a detection of a key phrase by the air-based microphone and a specific vibratory motion signature associated with the key phrase by the bone conduction microphone, andwherein, when the speaker verification operation is activated, a subsequent voice operation from the plurality of automated voice operations is to be activated if the air-based microphone detects that an identified key phrase was spoken by a known speaker and the bone conduction microphone detects a vibratory motion signature associated with the known speaker.
