 note = {application/pdf, Takushoku University, Inner Mongolia University, National Institute for Japanese Language and Linguistics, The principle which underlies modern Mongolian vowel harmony has been a matter of dispute. Many recent studies insist that the harmonic sets of vowels are phonetically distinguished in terms of the tongue root position (i.e., the size of the pharynx), while the distinction has been traditionally described by backness of the tongue.  As no crucial articulatory evidence has been provided so far, we investigated this problem using real-time magnetic resonance imaging. In this paper we present robust physiological evidence that the two harmonic sets of vowels can be distinguished in terms of size of the pharynx and degree of tongue height in modern East Mongolian.},
