Xumi features a very unusual phonemic contrast between voiceless /ʎ̥/ and voiced /ʎ/ alveolo-palatal lateral approximants and voiceless and voiced glottal fricatives.^[4][5]

1. Only in Upper Xumi
2. Only in Lower Xumi

• The close and close-mid series are the same in both varieties: /i, ʉ, u, e, o/. The difference lies in the open-mid and open series; in Upper Xumi, these are /ɛ, ɐ, ɔ, a/, whereas in Lower Xumi, they are /ɛ, ɐ, ɑ/.^[8][9]
  • At least in Lower Xumi /ʉ/, is phonetically close-mid [ɵ].^[10]
  • /ɐ/ is closer in Upper Xumi [ɜ]; in addition, the open central vowel /a/ is phonetically near-open [ɐ]. For this reason, they may be transcribed with ⟨ɜ⟩ and ⟨ɐ⟩, respectively.^[11]
  • The Lower Xumi /o/ and /ɑ/ generally correspond to Upper Xumi /u/ and /ɔ/, respectively. /ɑ/ is near-open near-back [ɑ̽] and thus similar to the Upper Xumi /a/, but more back.^[10][11]

• Upper Xumi has the following nasal vowels: /ĩ, ũ, ɛ̃, ɔ̃, ɐ̃/, as well as the marginal /ɘ̃/, which occurs only in the word [^LPmɘ̃da]^{[clarification needed]} 'on the roof / upstairs'.^[8]
• Lower Xumi has the following nasal vowels: /ĩ, õ, ɛ̃, ɐ̃, ɑ̃/, as well as the marginal /ə̃/, which occurs only in the word [^LPmə̃dɐ ᴿʁo]^{[clarification needed]} 'on the roof / upstairs'.^[9] /ẽ, õ, ɐ̃, ɑ̃/ generally correspond to Upper Xumi /ĩ, ũ, ɛ̃, ɔ̃/, respectively.^[11]
