Tik Tok is essentially a 15 second music short video community focusing on young people. If you choose fast, remove the volume of the original sound, and then click search directly, if someone speaks.
In the search box, enter the excerpt you want to add. There is a noise function in dubbing, in the pop-up soundtrack page.
Baidu searched Tik Tok, and the hot search list above intercepted the climax of music, not simply, and people have found many voices in it.
