Comparing acoustics and articulation: the impact of tongue and lip position on vowel acoustics

Description

A discussion of the impact that midsagittal tongue body position and lip position have on the first and second formant measurements, traditionally used to plot vowels in acoustic space. Using examples of the GOOSE vowel from the British Isles section of the Dynamic Dialects ultrasound tongue imaging and lip camera dataset. A region by region comparison of articulatory and acoustic measures shows a mismatch between tongue-only measures and F2 values, whereby Scottish and English and S. Irish speakers have very different tongue body frontness positions, but similar F2 values. This mismatch between acoustics and articulation can be attributed to differences in lip position in the accent groups studied.
