Abstract
Recent advances in real-time magnetic resonance imaging (rt- MRI) make possible the following study of post-dorsal coarticulatory effects on lateral approximants in running speech. As the MRI is particularly well-suited for investigating pharyngeal articulations, it was capable of capturing perseverative coarticulation from a low central vowel to the immediately following syllable-initial lateral approximant. The lowered and retracted tongue body position associated with a low central vowel is articulatorily equivalent to a pharyngeal constriction [1]. We show here that rt-MRI techniques can track coarticulation direction by calculating the average pixel intensity [2] within a region of interest in MR images as a function of time.
