Systems and Methods for Mitigating the Effect of Water Retained in a Microphone Port

A wearable computing device, the wearable computing device comprising:

• one or more processors,
• an audio sensor;
• a port connecting the audio sensor to an exterior of a surface of the wearable computing device;
• a non-transitory computer-readable memory;
• wherein the non-transitory computer-readable memory stores instructions that, when executed by the one or more processors, cause the wearable computing device to perform operations, the operations comprising:
• accessing port status data;
• determining, based on the port status data, a water presence likelihood value, the water presence likelihood value representing a likelihood that water is currently in the port;
• and
• in accordance with a determination that the water presence likelihood value exceeds a threshold, applying a digital correction filter to data produced by the audio sensor, wherein the digital correction filter corrects the data produced by the audio sensor to compensate for a presence of water in the port.
