Can WeChat voice also be used for big data detection?

Voice cannot be detected by big data.

WeChat voice is a network data transmission. Tencent encrypts voice calls. Even if it is intercepted, it will still be a bunch of character letters. If the voice is restricted, it may be because the call permissions are restricted.

WeChat voices can be monitored by the police, and Tencent has the responsibility and obligation to provide this information to the Internet police. For individuals, WeChat client software is transmitted through WeChat servers and firewalls, and will not be monitored during normal use. However, this does not rule out the possibility that the mobile phone may be invaded by a virus and WeChat voice may be monitored.
