The sounds of Choctaw have been described most extensively in Charles Ulrich's 1986 Ph.D. dissertation (see also Broadwell 2006).
Vowels in Choctaw may be short or long.
Short | Long |
ʋ /a/ | a /a:/ |
i /i/ | e /i:/ |
u /o/ | o /o:/ |
In Byington's time, the letter e /i:/ was pronounced as in they.
Vowels are also sometimes nasal, spelled with an underline in the traditional Choctaw spelling.
a̱ /ã/ | i̱ /ĩ/ | o̱, u̱ /õ/ |
There are thirteen consonants.
p | t | ch /ʧ/ | k | |
b | ||||
f | s | sh /ʃ/ | h | |
hl, lh /ɬ/ | ||||
l | ||||
w | y /j/ |
The voiceless lateral fricative is spelled hl before a vowel and lh before a consonant.
