Bickel, Balthasar. Belhare. 2003. wals:574
Bickel's /ʌ/ is grouped with the central vowel /a/, so is given here as /ɜ/. There is also "a nasality feature that associates with the preceding syllable, but is realized as an assimilating syllabic nasal when initial in the phonological phrase", given here as /n̩/.
