Very little linguistic documentation and descriptive research has been done on Stoney. However, Stoney varieties demonstrate broad phonological similarity with some important divergences.
For example, the following phonemes are reportedly found in Morley Stoney, spoken on the Morley Reserve:
Bilabial | Alveolar | Postalveolar | Palatal | Velar | Pharyngeal | Glottal | ||
---|---|---|---|---|---|---|---|---|
Stop | voiceless | p | t | t̠ | k | |||
voiced | d | d̠ | g | |||||
Affricate | voiceless | t͡ʃ | ||||||
voiced | d͡ʒ | |||||||
Fricative | voiceless | ɸ | s | ʃ | x | ħ | h | |
voiced | z | ʒ | ɣ | ʕ | ||||
Nasal | m | n | ||||||
Approximant | w | j |
Front | Central | Back | ||
---|---|---|---|---|
unr. | rnd. | |||
High | i, ĩ | ɯ | u, ũ | |
Mid | e | ɤ | o | |
Low | æ | a, ã | ɑ | ɒ |
For comparison, these phonemes reportedly characterize the Stoney spoken at Alexis Nakota Sioux Nation, which maintains the common Siouan three-way contrast between plain, aspirated, and ejective stops:
Bilabial | Dental | Palatal | Velar | Pharyngeal | Glottal | |
---|---|---|---|---|---|---|
Stops | p, pʰ, pʼ | t, tʰ, tʼ | k, kʰ, kʼ | ʔ | ||
Affricates | t͡ʃ, t͡ʃʰ, t͡ʃʼ | |||||
Fricatives | s, z | ʃ, ʒ | x, ɣ | h | ||
Nasals | m | n | ||||
Glides | w | j |
Notice that Alexis Stoney, for example, has innovated contrastive vowel length, which is not found in other Dakotan dialects. Alexis Stoney also has long and nasal mid vowels:
Front | Central | Back | |
---|---|---|---|
High | i, ī, ĩ | u, ū, ũ | |
Mid | e, ē, ẽ | o, ō, õ | |
Low | a, ā, ã |
