Pharyngealized

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.

Note that the terms pharyngealized, epiglottalized, strident, and sphincteric are sometimes used interchangeably.

One example is the emphatic consonants, which are pharyngealized in modern pronunciations but may have been velarized in the eighth century and glottalized in Proto-Semitic.

Some dialects have replaced emphatic consonants with non-emphatic counterparts, while those spoken in the Caucasus often have glottalized rather than pharyngealized emphatics.

The Juǀʼhoan language has 48 click consonants, among nearly as many non-click consonants, strident and pharyngealized vowels, and four tones.
