16. A method comprising: detecting a first sound representative of a target voice and a second sound representative of noise, the first sound being captured by a first microphone and the second sound being captured by a second microphone; implementing a delay with respect to a first audio signal that represents the noise and refraining from delaying a second audio signal that represents the target voice; terminating the delay based at least in part on detecting the noise; processing, by a first adaptive filter, the target voice to generate a target voice estimate, the target voice estimate representing a first estimate of the target voice of a user associated with the first sound; processing, by the first adaptive filter, the noise to generate a noise estimate, the noise estimate representing a second estimate of the noise within an environment associated with the user; and generating, by a second adaptive filter different from the first adaptive filter, an enhanced target voice based at least in part on at least one of the target voice estimate or the noise estimate.

The method as recited in claim 16 , further comprising: determining one or more words that correspond to the target voice based at least in part on the enhanced target voice; and causing an operation to be performed within an environment based at least in part on the one or more words.
