Features and description of vowels


Vocal folds vibration is the sound source for vowels. Therefore, all vowels are voiced. The supraglottal vocal tract (the part above the larynx) acts as the acoustic resonator modifying the sound made by the vocal folds. The quality of the vowels is determined by the shape of this resonator which in turn is determined by the tongue position and the lip rounding degrees.

Vowels are the most audible, intense, sonorant sounds and they function as the syllable nuclei. In contrast, consonants depend on vowels for their audibility. Vowels There are monophthongs (single vowels) and diphthongs (two-part vowels).

We know that when describing consonants, we talk about their manner and place of articulation and whether they are voiced or not. In comparison, vowels are described from the following four aspects: (1) tongue height, (2) tongue advancement, (3) lip rounding, and (4) tenseness.
