In phonetics, a vowel in which there is a noticeable sound change within the same syllable. (In contrast, a single or simple vowel is known as a monophthong.) Adjective: diphthongal.
The process of moving from one vowel sound to another is called gliding, and thus another name for diphthong is gliding vowel.
