diphthong
Let an agent explain diphthongs and their classification, describe diphthongs in specific languages and dialects, support transcription and pronunciation, and support learning phonetics.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Let an agent explain diphthongs and their classification, describe diphthongs in specific languages and dialects, support transcription and pronunciation, and support learning phonetics.
A vowel sound in which the tongue glides from one vowel quality to another within a single syllable, such as the vowels in English words like eye and how, classified as opening, closing or centring by the direction of movement and as rising or falling by which element is more prominent, and transcribed in the International Phonetic Alphabet with two vowel symbols; diphthongs contrast with monophthongs and vary across languages and dialects.
What it is for: Gliding vowel sounds within one syllable.
It can be explain classification; describe diphthongs in languages; support transcription and pronunciation; support learning.
Distinguishing features
Single syllable
Vowel quality change
Direction classes
Language-specific inventories
What it looks like
Not physical; a speech sound.
How it is recognised
Vowel glide within one syllable
Two vowel symbols in transcription
A monophthong is steady; a hiatus has two syllables
