Tobati permits three consonants in the onset, and at most a single consonant or a nasal-stop cluster in the coda.
Nasal-stop clusters only permit a nasal and a stop of the same place of articulation. For the /nd/ sequence, /n/ becomes dental [n̪]. Neither the bilabial, consisting of /b/ and the /f/ allophone [p], nor palatal nasal-stop clusters distinguish voice (i.e. they are [pm~bm] and [cɲ~d͡ʒɲ] respectively). The /Nk/ sequence voices to [ŋg].[2]
