The short-vowel diphthongs are {{IPA|/iu, ou, oi, eu, ei, au, ai, ao, ae/}}. In all except perhaps {{IPA|/iu/}}, these are [[falling diphthong]]s. However, they are not as tightly bound as the diphthongs of English, and may be considered vowel sequences.<ref name=":3" /> (The second vowel in such sequences may receive the stress, but in such cases it is not counted as a diphthong.) In fast speech, {{IPA|/ai/}} tends to {{IPA|[ei]}} and {{IPA|/au/}} tends to {{IPA|[ou]}}, conflating these diphthongs with {{IPA|/ei/}} and {{IPA|/ou/}}.

There are only a limited number of vowels which may follow long vowels, and some authors treat these sequences as diphthongs as well: {{IPA|/oːu, eːi, aːu, aːi, aːo, aːe/}}.
