Noise suppression wearable device

A method for suppressing noise associated with speech, the method comprising:

• performing an active noise cancellation (ANC) operation on noisy input speech as captured by a first microphone of a wearable device, the noisy input speech as captured by a second microphone of the wearable device, or both, to suppress a noise level associated with the noisy input speech as captured by the second microphone, wherein the second microphone is positioned within a threshold distance of an ear canal of a user;
• performing an equalization operation to match a second frequency spectrum of a second signal with a first frequency spectrum of a first signal, the first signal representative of the noisy input speech as captured by the first microphone, and the second signal representative of the noisy input speech as captured by the second microphone;
• generating an output speech signal that is representative of input speech based on the second signal having the second frequency spectrum that matches the first frequency spectrum;
• and
• transmitting a time-domain version of the output speech signal to a mobile device.

A non-transitory computer-readable medium comprising instructions for suppressing noise associated with speech, the instructions, when executed by one or more processors within a wearable device, cause the one or more processors to:

• perform an active noise cancellation (ANC) operation on noisy input speech as captured by a first microphone of a wearable device, the noisy input speech as captured by a second microphone of the wearable device, or both, to suppress a noise level associated with the noisy input speech as captured by the second microphone, wherein the second microphone is positioned within a threshold distance of an ear canal of a user;
• perform an equalization operation to match a second frequency spectrum of a second signal with a first frequency spectrum of a first signal, the first signal representative of the noisy input speech as captured by the first microphone, and the second signal representative of the noisy input speech as captured by the second microphone;
• and
• generate an output speech signal that is representative of input speech based on the second signal having the second frequency spectrum that matches the first frequency spectrum.

A wearable device comprising:

• first means for capturing noisy input speech;
• second means for capturing the noisy input speech, the second means for capturing configured to be positioned within a threshold distance of an ear canal of a user;
• means for performing an active noise cancellation (ANC) operation on the noisy input speech as captured by the first means for capturing, the noisy input speech as captured by the second means for capturing, or both, to suppress a noise level associated with the noisy input speech as captured by the second means for capturing;
• means for matching a second frequency spectrum of a second signal with a first frequency spectrum of a first signal, the first signal representative of the noisy input speech as captured by the first means for capturing, and the second signal representative of the noisy input speech as captured by the second means for capturing;
• means for generating an output speech signal that is representative of input speech based on the second signal having the second frequency spectrum that matches the first frequency spectrum;
• and
• means for transmitting a time-domain version of the output speech signal to a mobile device.
