Mouth Movements
Early-Concentrate111
On YouTube, almost every American English pronunciation channel uses exaggerated mouth movements. For example, when pronouncing the long “o” vowel, their lips look like they’re about to kiss someone.
I tried that and noticed that my pronunciation sounded better. So why don’t native speakers do it? I live in the U.S. and see hundreds of people speaking every day, and none of their mouth movements look like that. Yet, they sound way better than me. In fact, most of their lip movements aren’t even that noticeable. I don’t get it.
