The vowel is a sound in the production of which the air stream does not meet an obstruction and there is no noise component

2. Vowels are classified according to:

- the stability of articulation

- the tongue position

- the lip position

- the length of the vowel

3. According to the stability of articulation vowels are divided into monophthongs, diphthongs and diphthongoids.

The articulation of monophthongs is almost unchanging throughout their pronunciation.

In the articulation of diphthongs the organs of speech glide from one vowel position to another within one syllable. Each diphthong consists of two elements: the nucleus and the glide. The nucleus is strong and distinct; the glide is weak, its articulation is not fully accomplished.

Diphthongoids are characterized by some change in the articulation between the starting point and the end but the difference is not so distinct as in diphthongs.

3. According to the tongue position vowels are divided into front, back and central. A front vowel is produced when the tongue is in the front part of the mouth cavity and its front part is raised. The tongue may be slightly retracted, then the vowel is front-retracted. When the tongue is in the back part of the mouth cavity and its back part is raised towards the soft palate, back vowels are produced. The tongue may be slightly advanced, then the vowel is back-advanced. When the central part of the tongue is raised, the vowel is central.

Depending on the height of the raised part of the tongue, vowels are divided into close, open and mid.

A close vowel is produced when the tongue is raised high towards the palate. An open vowel is produced when the tongue is placed low in the mouth cavity. Mid vowels are produced when the position of the tongue is intermediate between the highest and the lowest.

To make the classification of vowels more precise, it is necessary to distinguish broad and narrow variants.

4. According to the lip position vowels are rounded (with the lips rounded) and unrounded (with the lips neutral or spread).
