Abstract
A noise cancellation processing method, device and apparatus are provided. The noise cancellation processing method includes: collecting first voice data in a surrounding environment by using a noise-cancelling earphone in response to detecting that the noise-cancelling earphone is in a wearing state and a noise cancellation mode is enabled; extracting to-be-recognized voiceprint feature information according to the first voice data; identifying similarities between registered voiceprint feature information stored in a registered voiceprint database and the to-be-recognized voiceprint feature information entry by entry; and in response to at least one of the similarities being greater than a first preset threshold, performing a preset action in the noise-cancelling earphone.
