The phonology is not certain, but the following has been suggested (Ehret 1980):
| m | n | ɲ | ŋ | |||
| b | d | ɡ | ɡʷ | |||
| p | t | k | kʷ | ʔ | ||
| tsʼ | tɬʼ | tʃʼ | kʼ | kʼʷ | ||
| f | s | ɬ | x | xʷ | h | |
| β̞ | dz | l | j |
/ɡ/ and /l/ have the allophones [dʒ] and [ɽ] before front vowels. /tʃʼ/ is 'mildly' ejective. Ehret reports that /kʼ/ and /kʼʷ/ are voiced [ɡ, ɡʷ] if a preceding consonant is voiced.
Vowels are /a e i o u/.
