The voiceless labialized uvular fricative occurs only in some speech variants and doesn't contrast with its voiced counterpart /ʁʷ/. The voiceless alveolar affricate is an allophone of /tʃ/ before the schwa vowel. The voiced labiovelar approximant is a realization of /v/ between vowels other than the schwa.
/l/ is not phonetically a fricative, but behaves as one phonologically. /j/ is pronounced /tʃ/ in the Hooper Bay-Chevak and Nunviak dialects. Fricatives (and /l/) devoice immediately before or after a plosive, while nasals devoice only immediately after a plosive or a voiceless fricative.
