Albuquerque, Francisco Edvige. 2008. Contribuição da fonologia ao processo de educação indígena Apinajé. Universidade Federal do Tocantins.
The dissertation focuses on a re-study of Apinajé phonology, and the implications of the results of this study for the Apinajé orthography and the teaching materials used in Apinajé bilingual education programs. On the phonological front, the author concludes that previous analyses of the Apinajé phonological inventory were flawed due to the inclusion of three nasal mid vowels, which he concludes are not contrastive in Apinajé. He includes a very interesting discussion of the practical and political issues surrounding the Apinajé orthography raised by the new phonological findings.
