Vowels are sounds produced without any barrier in mouth. When we pronounce a vowel, air flows freely to create sound. The sound is modulated by moving tongue up or down, closer to or further from the palate, and by changing the shape of lips.
In Serbian language there are only 5 vowels: i, e, a, o and u. That’s less then in English.
They are pronounced consistently – always the same way.
|I||lips stretched to a smile,tongue close to palate, jaws together|
|E||jaws open a bit, tongue drops a bit down from the palate|
|A||lips in neutral position, mouth wide open, tongue away from the palate|
|O||lips form circular shape, lower jaw moves up|
|U||lips still rounded, lower jaw moves further up|
