Abstract

The present application discloses an identity recognition method, device and system. Wherein, the method includes: acquiring the voiceprint feature of the target object and a first timestamp, wherein the first timestamp is used to represent the time when the voiceprint feature is acquired; acquiring the voiceprint feature from a voiceprint database that is successfully matched with the voiceprint feature Pre-stored voiceprint features and a second time stamp, wherein the second time stamp is used to represent the time when the pre-stored voiceprint features are obtained; based on the first time stamp and the second time stamp, a similarity threshold is determined; based on the similarity threshold, As well as the similarity between the voiceprint feature and the pre-stored voiceprint feature, the recognition result of the target object is obtained. The present application solves the technical problem that the identification accuracy of the identification method in the prior art is low.

Description

technical field [0001] The present application relates to the field of voiceprint recognition, and in particular, to an identity recognition method, device and system. Background technique [0002] Smart speakers are tools for family members to access the Internet through voice, such as on-demand songs, online shopping, or knowing the weather forecast. It can also control smart home devices, such as opening curtains, setting refrigerator temperature, and warming up the water heater in advance. In order to improve the security of the smart speaker and prevent non-family members from illegally controlling the smart speaker, family members need to register in the smart speaker and perform identity authentication before each control. [0003] However, demand background: due to the environmental information contained in the audio registered by the user, as well as the speaker's own information, subtle or large changes will occur over time, including environmental noise (such as h...
