Abstract

It has been shown for several languages that subglottal resonances (SGRs) play a dividing role in thefrequency space of consonants and vowels (e.g. vowels are separated into the back-front categories bythe second subglottal resonance). Consonant-vowel transitions are characterized by a regression line(locus equation), and can be classified into distinct categories in the locus equation space, accordingto their place of articulation. Several attempts have shown that the dividing lines between thesecategories may be the SGRs. In this paper, the relation between CV transitions in the locus equationspace and the separating role of the subglottal resonances are further investigated. Locus equationspace of one native speaker of Hungarian is examined. Consonant-vowel transitions are classifiedbased on SGRs estimated from the locus equations of a subset of CV sequences. The hit rates andfalse alarm rates of the classification are comparable to a baseline experiment where the subglottalresonances were measured from accelerometer signal.
