Consonants
Heterorganic affricates[edit] Although most affricates are homorganic, Navajo and Chiricahua Apache have a heterorganic alveolar-velar affricate [tx] (Hoijer & Opler 1938, Young & Morgan 1987, Ladefoged & Maddeison 1996, McDonough 2003, McDonough & Wood 2008, Iskarous, et al. 2012). Wari' and Pirahã have a voiceless dental bilabially trilled affricate [t̪ʙ̥] (see #Trilled affricates), English has [ks], gz, and kʃ. Other heterorganic affricates are reported for Northern Sotho (Johnson 2003) and other Bantu languages such as Phuthi, which has alveolar–labiodental affricates [tf] and [dv], and Sesotho, which has bilabial–palatoalveolar affricates [pʃ] and [bʒ]. Djeoromitxi (Pies 1992) and Greek (modern) have [ps] and [bz].

Vowels
Diphthongs have high quality than short vowels. For example: aɪ, aɪ̯, aj, aʊ, aʊ̯, eɪ, eʊ, ɛj, eə, ij, ɪə, ja, jæ, jä, je, jɛ, ji, jɪ, jo, jɔ, jɵ, ju, jy, jʉ, ɒʊ, ɔɪ, ɔʊ, oʊ, œj, uj, ʊɪ, wa, ɥi.

So do triphthongs: aɪə, aʊə, ɔɪə, jʊə.
