Klamath phonology

Consonants
Obstruents in Klamath except for all come in triplets of unaspirated, aspirated, and ejective sounds. Sonorant triplets are voiced, voiceless, and "laryngealized" sounds, except for and.

Most consonants can be geminated. The fricative is an exception, and there is evidence suggesting this is a consequence of a recent sound change. Albert Samuel Gatschet recorded geminated in the late 19th century, but this sound was consistently recorded as degeminated  by M. A. R. Barker in the 1960s. Sometime after Gatschet recorded the language and before Barker did the same, may have degeminated into.
