This study investigated the effect of palate morphology and anthropometric measures of the head and face on lingual consonant target (positional) variability of twenty one adult speakers (eleven male, ten female). An electromagnetic tracking system (WAVE, NDI, Canada) was used to collect tongue movements while each speaker produced a series of VCV syllables containing a combination of consonants /t, d, s, z, ʃ, tʃ, k, g, j/ and three corner vowel /i, ɑ, u/. Distributions of x, y, and z coordinates representing maximum tongue elevation during the consonants were used to represent target variability across contexts. Palate and anthropometric measures were obtained for each participant. A correlational analysis showed that target variability of the consonants produced in the front of the mouth (e.g. alveolar and palatal) was explained, to a degree, by palate morphology. The variability of velar consonants was not explained by the structural measures.
