From the introduction: "This brief paper is largely an exercise in lily-gilding, building upon Frantz's insightful analysis of Cheyenne phonology. What I will attempt to do in this paper is to rework some of his rules relating to the devoicing of vowels and raise some questions as to whether these rules confirm the need for a controversial device in the theory of grammar."
