[ɾ] and [l] are in a free variation.
[w] and [j] are not included in a phoneme chart in Kisi because they only occur as glide insertion between historically or morphologically adjacent vowels. [w] does not occur otherwise. For some speakers, [j] occurs as a free variant of [ʝ] which is considered incorrect by other speakers.

Contrastive and obligatory length is marked with /:/. This does not necessarily reflect a difference in the length of production.
