Celinese: Phonology: Voicing in Plosives and Fricatives: In both plosives and fricatives

Partial - some voice/voiceless contrasts:

Contrast: /p/ and /b/, /k/ and /g/, /f/ and /v/ (<f>), /θ/ (th) and /ð/ (ð).

No contrast: In terms of most fricatives, usually, the language has the voiced consonant but not its voiceless equivalent: /s/ but no /z/, /ç/ (final -g) but no /ʝ/, /χ/ (<ch>) but no /ʁ/ and both /ʂ/ and /ʐ/ allophonically.
