当你在看歌唱表演时，是否怀疑过歌手是真唱还是假唱吗？虽然如今有不少科技手段可以来辅助判断，但这几种方法也可以简单判别。
Ah, yes, the lip-syncing pop star.
Few things are more gratifying than calling out music fakery, exposing performers who dare pretend they're singing, but sometimes it's hard to tell.
Luckily, there are experts who have laid out some useful tips for how to separate the live singers from the mothers-along.
Number one, check for the position of the mic.
If the singer is moving the mic all over the place and the level of the vocals isn't affected, that's a tell.
Or, as is the case with this infamous 1984 performance by Queen, if they are not even attempting to sing into the mic, they're lip-syncing.
Number two, does the vibrato you hear in the song match the singer's vibrating vocal cords?
You can tell Celine is singing here because you can see them contracting as she exerts some hardcore vibrato.
Number three: are they dancing like there's no tomorrow?
Then there's a very good chance they're not singing live.
