Lexical-tone languages use fundamental frequency (F0/pitch) to convey word meaning. About 41.8% of the world's languages use lexical tone (Maddieson, 2008), yet those systems are under-studied. I aim to increase our understanding of speech-sound inventory organization by extending to tone-systems a model of vowel-system organization, the Theory of…

A phonetic study of vowel devoicing in the Shanghai dialect of Chinese explored the phonetic conditions under which the high, closed vowels and the apical vowel in Shanghai are most likely to become devoiced. The phonetic conditions may be segmental or suprasegmental. Segmentally, the study sought to determine whether a certain type of pre-vocalic…

This paper reviews the evidence that Proto-Niger-Congo was a tone language with only two level tones and seeks to find the evidence that will explain how some of the descendant languages have more than two tones. In particular it shows how synchronic tone rules in Cama and consonant correspondences between Cama and Yoruba suggest a new factor in…
