Wearable device with speech enhancement

A method for audio signal processing in a device, the method comprising:

• receiving, at a first sensor coupled to the device, a first audio signal;
• receiving, at a second sensor coupled to the device, a second audio signal;
• determining a minimum variance distortionless response (MVDR) using at least the second audio signal;
• determining that a condition of an environment of the device is windy when an energy of the MVDR is greater than an energy of the second audio signal by a wind factor;
• determining that the condition of the environment of the device is not windy when the energy of the MVDR is less than the energy of the second audio signal by the wind factor;
• and
• determining a mixed audio signal using the condition of the environment of the device and at least one of the first audio signal, the second audio signal, or the MVDR.

A non-transitory computer-readable medium comprising computer-executable instructions that, when executed by one or more processors of a device, cause the device to perform a method for audio signal processing, the method comprising:

• receiving, at a first sensor coupled to the device, a first audio signal;
• receiving, at a second sensor coupled to the device, a second audio signal;
• determining a minimum variance distortionless response (MVDR) using at least the second audio signal;
• and
• determining that a condition of an environment of the device is windy when an energy of the MVDR is greater than an energy of the second audio signal by a wind factor;
• determining that the condition of the environment of the device is not windy when the energy of the MVDR is less than the energy of the second audio signal by the wind factor;
• determining a mixed audio signal using the condition of the environment of the device and at least one of the first audio signal, the second audio signal, or the MVDR.
