There are four basic vowels in Plains and Swampy Cree: a, i, e and o. The a, i and o sounds also have long versions: â, î and ô. The vowel e is always long and is written as ê. In Woods Cree, ê has merged with î, so only three basic vowels are used in that dialect. Woods Cree also has the phoneme th /ð/ (the "th" from the English word "th"at). For more on Cree dialects see the article on the Cree language.
