Abstract

The syllabic liquids [ɚ] (as in “purr”) and [əɫ] (as in “pull”)
have well-defined acoustic targets but are produced with a
wide range of heterogenous tongue postures. This work
surveys midsagittal tongue shapes from a large (N=78)
number of speakers producing these sounds, to illustrate their
variety, and to determine systematically how this variety can
be quantified. In particular we propose that a categorization
based on just two parameters––degree of tongue dorsum
convexity and tip orientation––is sufficient to classify
observed shapes, and superior to defining ad hoc prototypes.
