It is surely incontestable that the IPA alphabet, like the system of vowel and consonant classification on which it is based, contains obvious anomalies; some or others of which have been discussed in recent proposals for reform (e.g. Breckwoldt 1971, McClure 1972, Hammarström 1973). Fox (1975), in an interesting attempt to widen the scope of the discussion, has argued that the anomalies are less serious than they appear, on the grounds that (a) they do not interfere with the practical usefulness of the alphabet, and (b) a more positive and more fundamental point—they reflect in some cases what appear to be linguistic universals, such as the potential use of retroflex consonants as a distinctive category and the widespread preference for voiced over voiceless nasals.
