Vowel harmony - Other types of harmony

Although vowel harmony is the most well-known harmony, not all types of harmony that occur in the world's languages involve only vowels. Other types of harmony involve consonants (and is known as consonant harmony). Rarer types of harmony are those that involve or tone or both vowels and consonants (e.g. postvelar harmony).

Vowel harmony - Vowel-consonant harmony

Some languages have harmony processes that involve an interaction between vowels and consonants. For example, Chilcotin has a phonological process known as vowel flattening (i.e. post-velar harmony) where vowels must harmonize with uvular and pharyngealized consonants.

Chilcotin has two classes of vowels:

• "flat" vowels [ᵊi, e, ᵊɪ, o, ɔ, ə, a]
• non-"flat" vowels [i, ɪ, u, ʊ, æ, ɛ]

Additionally, Chilcotin has a class of pharyngealized "flat" consonants [ʦˤ, ʦʰˤ, ʦ’ˤ, sˤ, zˤ]. Whenever a consonant of this class occurs in a word, all preceding vowels must be flat vowels.

If flat consonants do not occur in a word, then all vowels will be of the non-flat class:

Other languages of this region of North America (the Plateau culture area), such as St'át'imcets, have similar vowel-consonant harmonic processes.
