The Haitian Creole vocalic system includes both nasalized and oral varieties. Relatively recent analyses can be found in Hall 1953, D'Ans 1968, Valdman 1970, Férère 1977 and Férère 1979. Férère 1977 deals specifically with the oral front rounded phonemes. The solutions proposed by the various creolists do not always coincide. In this paper, the writer, a native speaker of Haitian Creole, does not intend to make a detailed study of their findings, but simply to review the different treatments offered for vowels and semiconsonants, in general, and to propose one which he believes to be most appropriate for the nasalized varieties in particular.
