1 . A system comprising:
a first detector that receives a first signal and a second detector that receives a second signal and a third signal, wherein the first signal comprises a skin surface microphone signal;
a static equalization filter coupled to the first detector and configured to generate an equalized first signal;
a voice activity detector coupled to the first detector, the voice activity detector generating a voice activity detector signal when the first signal corresponds to voiced speech; and
a wind detector coupled to the second detector, wherein the wind detector is configured to correlate the second signal and the third signal received at the second detector and to derive from the correlation a plurality of wind metrics comprising a first wind metric, a second wind metric, and a third wind metric that is associated with a wind noise that is an acoustic disturbance corresponding to at least one of air flow and air pressure in the second detector, the wind detector is further configured to determine a magnitude associated with the wind noise using the first wind metric, to determine whether to suspend an activity of the system using the second wind metric, and to use the third wind metric to determine a duration of time that the magnitude associated with the wind noise exceeds a threshold, wherein exceeding the threshold causes the system to switch from a first state to a second state,
wherein the wind detector controls a configuration of the second detector according to the plurality of wind metrics,
wherein the wind detector uses the plurality of wind metrics to dynamically control mixing of the first signal and the second signal to generate an output signal for transmission.
