Nowadays， WeChat is the most popular social app in China.
In 2014, WeChat released a new version in iOS. The most important trying is the addition of “voice lock” as a choice to login your account. Users can activate this function in set mode. After logoff and then log in again, the choice will appear and users can just say the numbers out and login their WeChat. But now the function is just in grey on-line phase, only part of the WeChat users can try it.
There is no doubt that the technology behind is speaker recognition. As you can see, speaker recognition can also play an important role in identify a person’s features, and this technology will be more and more applied in real life applications.
However, you must have noticed that speaker recognition is not that widely in used in internet products. There are mainly constraints that influence it. The main reason I think may be people are still not feel so safety in using it. As each time only a short utterance is used for identification and verification, the accuracy is very dependent on the technology itself. The second reason may be that it also depends on how the user speaks to it. The same user can say the same sentence in different ways without notice it. Besides, the developers have to also find solution to against the recording of people’s voice to be verified.
