Abstract

The invention discloses an identity recognition method, device and system. The method comprises: acquiring voiceprint features and a first timestamp of a target object, wherein the first timestamp isused for representing the time when the voiceprint features are acquired; obtaining a pre-stored voiceprint feature successfully matched with the voiceprint feature and a second timestamp from a voiceprint library, the second timestamp being used for representing the time when the pre-stored voiceprint feature is obtained; determining a similarity threshold based on the first timestamp and the second timestamp; and obtaining a recognition result of the target object based on the similarity threshold and the similarity between the voiceprint features and the pre-stored voiceprint features. According to the invention, the technical problem of low identification accuracy of an identity identification method in the prior art is solved.

Description

technical field [0001] The present application relates to the field of voiceprint recognition, and in particular, to an identification method, device and system. Background technique [0002] A smart speaker is a tool for family members to surf the Internet through voice, such as ordering songs, shopping online, or understanding the weather forecast. It can also control smart home devices, such as opening curtains, setting the temperature of the refrigerator, and heating the water heater in advance. In order to improve the security of smart speakers and prevent non-family members from illegally controlling smart speakers, family members need to register with smart speakers and perform identity authentication before each control. [0003] However, the demand background: Due to the environmental information contained in the audio registered by the user, as well as the information of the speaker itself, as time goes by, subtle or large changes will occur, including environmenta...
