- Abstract
- This study investigated the extent to which speaker-induced control and biomechanics play a role in determining the outcome of spatial coarticulation. Employing ultrasound tongue imaging, coarticulatory effects from and induced on adjacent consonants were quantified as measures of coarticulatory resistance and aggressiveness for the two apical vowels of Standard Mandarin in comparison to the three corner vowels. The results show that the two apical vowels are much less resistant to coarticulatory effects than the vowels [i a u], and they often do not induce larger effects on adjacent consonants than these vowels, due to speaker-targeted effects. It was also found that the retroflex apical vowel was consistently more resistant and aggressive than the dental apical vowel, due to biomechanical differences. Together, both of these findings implicate the roles of speaker control and biomechanics in coarticulation and highlight the need for a model of coarticulation to include both of these factors.
