UPGRADING METHOD AND APPARATUS, AND ELECTRONIC DEVICE

Embodiments of this application provide an upgrade method, an upgrade apparatus, and an electronic device. The method includes: An electronic device acquires a first verification voice entered by a user; processes the first verification voice by using a first model stored in the electronic device, to obtain a first voiceprint feature; verifies an identity of the user based on the first voiceprint feature and a first user feature template stored in the electronic device; after the identity of the user is verified, if the electronic device has received a second model, processes the first verification voice by using the second model, to obtain a second voiceprint feature; and updates the first user feature template based on the second voiceprint feature, and updates the first model by using the second model. In embodiments of this application, a verification voice obtained in a verification process is used as a new registration voice to complete upgrade and registration of a voiceprint recognition system, so that upgrade of the voiceprint recognition system can be implemented without user perception, and both voiceprint recognition performance and user experience can be improved.
