A diphthong is a vowel whose quality changes significantly in one direction during its pronunciation.
- "When the medial phase shows an audible change of quality, with the change consistently progressing toward a single target, as it were, then the sound is classified as a diphthong." (Laver 1994:146)
Examples
[ai] in English wine, [au] in English house.
Comments
Often phonologists do not agreee whether a tautosyllabic sequence of two sounds is a diphthong or a sequence of vowel plus glide, or glide plus vowel.
Subtypes
