Wells, A study of the formants of the pure vowels of British English
A State Studentship awarded by the Ministry of Education made this work possible.
I wish to record my gratitude to the Joint Speech Research Unit, Eastcote, for the generous loan of their spectrograph; particularly also to Professor D.B. Fry, Professor of Experimental Phonetics in the University of London, and to Dr A.J. Fourcin, of the Department of Phonetics, University College, for their advice, help, and encouragement.
