The contrast between bilabial and labiodental fricatives is comparatively rare in the world's languages. In his survey of 317 languages Maddieson (1984) notes only one that has the full set of voiced and voiceless sounds [φ, β, f, v], and only four other languages that contrast just the voiced pair. There is no doubt that these contrasts do occur, and that phonologists such as Sagey (1986) are wrong in neglecting to provide for them. This note will provide further particulars of the contrast in languages in which it has not been so well documented in the general linguistic literature. It will also suggest that this contrast may not be made in the same way in all languages, and discuss the implications for the IPA and for theories of phonetic description.
