Subglottal resonances are claimed to divide front/back vowels and low/high vowels in several languages, including Hungarian. However, some 'recalcitrant' vowels appear to resist this mould. We therefore performed a careful analysis of the role coarticulation and speaker-dependent effects might play in the recalcitrance of these vowels in Hungarian. The present analysis focused on various stop contexts in order to see the place of articulation triggered effects. It is shown that the subglottal resonances indeed divide the vowel space as claimed, and that the recalcitrance of certain vowels is due to coarticulation with specific consonants. The magnitude of the coarticulation effect is speaker dependent.
