===Vowels===
Cheyenne has three basic [[vowels|vowel qualities]] {{IPA|/e a o/}}. The phoneme called {{IPA|/e/}} here is usually pronounced as a phonetic {{IPA|[ɪ]}}, and sometimes varies to {{IPA|[ɛ]}}. 

These vowel qualities take four [[tone (linguistics)|tone]]s: [[high tone]] as in '''{{lang|chy|á}}''' {{IPA|[á]}}); [[low tone]] as in '''{{lang|chy|a}}''' {{IPA|[à]}}; [[mid tone]] as in '''{{lang|chy|ā}}''' {{IPA|[ā]}}; and [[rising tone]] as in '''{{lang|chy|ô}}''' {{IPA|[ǒ]}}. Tones are often not represented in the orthography. Vowels can also be [[voicelessness|voiceless]] (e.g. '''{{lang|chy|ė}}''' {{IPA|[e̥]}}).<ref>Linguist Wayne Leman included one more variant in his 1981 article on Cheyenne pitch rules, a lowered-high pitch (e.g. à), but has since recognized that this posited pitch is the same as a low tone.</ref> The high and low tones are [[phonemic]], while voiceless vowels' occurrence is determined by the [[phonetic environment|phonetic context]], making them [[allophone]]s of the voiced vowels.
