Abstract
In this paper, a summary is given of an experimental technique to address a known issue in \nresearch on the independent effects of nasalization on vowel acoustics: given that the separate \ntransfer functions associated with the oral and nasal cavities are merged in the acoustic signal, \nthe task of teasing apart the respective effects of the two cavities seems to be an intractable \nproblem. The results obtained from the method reveal that the independent effects of nasalization on the acoustic vowel space are: F1-raising for high vowels, F1-lowering for non-high \nvowels, and F2-lowering for non-front vowels. The results from previous articulatory research \nperformed by the author on the production of vowel nasality in French, Hindi, and English are \ndiscussed in the light of these independent effects of nasalization on vowel quality.
