Shape coarticulation in the spatial frequency domain: An example using /ɹ/

One facet of coarticulation is tongue shape assimilation to surrounding segments. This study demonstrates the use of the Fourier transform for quantifying the effect of rhotics on surrounding sounds. Ultrasound images taken from American English speakers producing a rhotic-heavy sentence are used as test data. The method shows promise for describing shape coarticulation without the need for head stabilization. Potential uses of this method involve quantification of speech motor control strategies among different groups of speakers, such as children acquiring language and speakers with disorders of the speech motor system.
