Method and device for identity recognition

Abstract

The embodiment of the invention provides a method and device for identity recognition, and relates to the technical field of televisions. The method and device are used for improving the accuracy of user identity recognition. The method comprises the steps that a voice signal of a user is received; a first parameter of the voice signal is extracted; first model matching is respectively carried out on the first parameter and a prestored first model parameter, and the maximum first probability matched with a first model is determined; second model matching is respectively carried out on the first parameter and a prestored second model parameter, and the maximum second probability matched with a second model is determined; the maximum first probability is compared with a first threshold value, and if the maximum first probability is not smaller than the first threshold value, the maximum second probability and the maximum first probability are operated; an operation result is compared with a second threshold value, and the user is determined as a user corresponding to the maximum second probability if the operation result is not smaller than the second threshold value.

Description

technical field [0001] The invention relates to the technical field of television, in particular to an identification method and device. Background technique [0002] In today's highly information-based life, TV equipment has already surpassed the basic attributes of simply watching movies and videos, and has been replaced by the intelligence of TV equipment. Among them, smart voice TV equipment is a type of smart TV equipment. In order to meet the needs of users, the existing intelligent voice TV equipment is provided with two working modes, that is, a general mode and a personalized mode. In the general mode, the TV device directly performs the corresponding playback operation according to the voice command input by the user; in the personalized mode, the TV device recommends programs to the user according to the user's access records, so that the user can choose his favorite program. [0003] In the prior art, when the smart voice TV device is started, it is in the gener...

[0004] In the above method for realizing mode switching, when the voiceprint recognition method is used to switch the general mode to the personalized mode, when the voiceprint characteristics of user A and user B are very close, if the television device recognizes the identity of user A, The TV equipment extracts the voiceprint information of user A from the received voice signal of user A, and matches the voiceprint information of user A with the voice information data stored in the memory. At this time, there may be voiceprint information of user A If it matches the voice information data of user B stored in the memory, the determined user is user B, that is, the user identity is wrongly identified, thus causing the TV device to recommend user B's favorite programs to user A according to user B's access records

Therefore, when the method of voiceprint recognition is used to determine the identity of the user, the accuracy of user identity recognition is not high
