Abstract :
Conventional quantification theory and a nonlinear quantification theory have been used to investigate the influence of phonemic context on the variation of vowel spectra. Using the distinctive features of the surrounding phonemes, the one-dimensional distribution of /a/,/i/ and /e/ and the two-dimensional distribution of /u/ and /o/ have been successfully modeled. As a result, some primal factors which affect the vowel spectra are apparent
