Lingual contact in selected English vowels and its acoustic consequence

This paper provides preliminary data about EPG contact for 3 different vowels in Southern British English (SBE) and Scottish English (SE) across eleven speakers. The EPG data were compared with vowel formants to test the hypothesis that the amount of EPG contact as an indicator of tongue height or anteriority will result in a corresponding change in F1 and F2. The results suggest that Percent Contact varies with the three monopthongs. F1, F2 and F2-F1 difference varies with the amount of Percent Contact.casl[1] Stone, M., Lundberg, A. 1996.
