1. A noise cancellation processing method, comprising:
collecting first voice data in an environment surrounding a noise-cancelling earphone in response to the noise-cancelling earphone being in a wearing state and a noise cancellation mode being 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;
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, such that an external sound is transmitted to a target user wearing the noise-cancelling earphone,
wherein, before the step of identifying the similarities between the registered voiceprint feature information stored in the registered voiceprint database and the to-be-recognized voiceprint feature information entry by entry, the noise cancellation processing method further comprises registering specified voiceprint feature information to form the registered voiceprint database.
