A little change in the position of your mouth can make you produce a different vowel sound and, consequently, change the meaning of what you wanted to say.

Have you ever heard a Spaniard pronouncing the word «sheet»? -This is definitely a word that many Spanish natives avoid when they speak in English, as well as the word «beach».


Picture a Spanish native saying his boss: «I’ll bring you the shit in a minute». (It wouldn’t be rare at all). We have a very strong accent because, among other things, our vowels are totally different from yours and the other way around!

Position of your lips

Unrounded (a, e i)

There isn’t much tension in your lips. Your lips are relaxed.

Rounded (o, u)

When a vowel requires you to round your lips to pronounce it, that’s exactly what you should do. Take it to the verbatim because you have to round your lips more than in English. If you don’t see wrinkles on your lips, they aren’t rounded enough.

These two Spanish vowels are pronounced by placing your tongue close to the teeth.

This vowel is pronounced with your tongue in the middle of the mouth, between your teeth and throat.
