The term gliding vowel is a reference to the way in which the airflow glides or moves from one vowel sound articulation to another. A vowel becomes a diphthong when it starts as one speech sound and ends as another. When air flows through vocal cords, it is manipulated by the lips, teeth, tongue, and the vocal cords themselves in order to produce the desired speech sound. These sounds are represented by symbols that we know of as letters. Each sound requires different alteration and constriction of the vocal cords to articulate.

With all speech sounds, including vowels and consonants, air flows through the vocal cords. This term relates to the way in which the vowel sound is articulated.


Diphthongs are sometimes referred to as gliding vowels. They can be achieved through the use of two consecutive vowels, as well as one vowel that changes as it is pronounced. Diphthongs are vowel sounds that begin as one sound and blend into another when they are articulated.
