c, c̕ , s
c is pronounced as a combination of t and s as in the English word ‘hats.’ In English this ts sound can occur only at the end or in the middle of words, not at the beginning. In Klallam, it commonly occurs at the beginnings of words.
c̕ is ejective. It is like c but ‘ejected’ out of the mouth with a strong pop.
s is the same as the sound at the beginning and end of English ‘sis.’
