The aim of our study is to analyse the articulatory characteristics of /iː/ occurring in Hungarian monosyllabic harmonic and antiharmonic stems. In their frequently cited work, based on 3 speakers’ data, Beňuš and Gafos (2007) [1] claimed that the tongue position in transparent vowels of antiharmonic Hungarian stems is less advanced than that of the phonemically identical vowels in harmonic stems. In their study, the authors compared different harmonic and antiharmonic stems (even if the consonantal context was more or less controlled).

In the present study, we analysed two homophonous pairs of words /siːv/ and /ɲiːr/, which are antiharmonic in their verbal usage, but are harmonic as nouns. The words were produced by 4 speakers both (i) in isolation and (ii) in sentence-initial position, where they were followed by front and back vowels, in a well-controlled manner. The experiment was carried out using electromagnetic articulography. We compared the sequence of the horizontal position of four receiver coils (ttip, tbl, tbo1, tbo2) across the conditions with Generalized Additive Models. The results showed that the horizontal positions of the receivers did not vary as a function of the harmonicity of the stem in either the isolated or the coarticulated condition.
