A fundamental problem in spoken language is the duality between the continuous aspects of phonetic performance and the discrete aspects of phonological competence. We study two instances of this problem from the phenomenon of voicing neutralization and vowel harmony. In each case, we present a model where the experimentally observed continuous distinctions are linked to the discreteness of phonological form using the mathematics of nonlinear dynamics.

ABSTRACT. Linguistic form is expressed in space, as articulators effect constrictions at various points in the vocal tract, but also in time, as articulators move. A rather widespread assumption in theories of phonology and phonetics is that the temporal dimension of speech is largely irrelevant to the description and explanation of the higher-level or more qualitative aspects of sound patterns. The argument is presented that any theory of phonology must include a notion of temporal coordination of gestures. Linguistic grammars are constructed in part out of this temporal substance. Language-particular sound patterns are in part patterns of temporal coordination among gestures. 1 1.

Using a combination of magnetometry and ultrasound, we examined the articulatory characteristics of the so-called ‘transparent ’ vowels [i�], [i], and [e�] in Hungarian vowel harmony. Phonologically, transparent vowels are front, but they can be followed by either front or back suffixes. However, a finer look reveals an underlying phonetic coherence in two respects. First, transparent vowels in back harmony contexts show a less advanced (more retracted) tongue body posture than phonemically identical vowels in front harmony contexts: e.g. [i] in buli-val is less advanced than [i] in bili-vel. Second, transparent vowels in monosyllabic stems selecting back suffixes are also less advanced than phonemically identical vowels in stems selecting front suffixes: e.g. [i�] in ír, taking back suffixes, compared to [i�] of hír, taking front suffixes, is less advanced when these stems are produced in bare form (no suffixes). We thus argue that the phonetic degree of tongue body horizontal position correlates with the phonological alternation in suffixes. A hypothesis that emerges from this work is that a plausible phonetic basis for transparency can be found in quantal characteristics of the relation between articulation and acoustics of transparent vowels. More broadly, the proposal is that the phonology of transparent vowels is better understood when their phonological patterning is studied together with their articulatory and acoustic characteristics.

We examine the phonetic characteristics of yer and non-yer vowels in Slovak in an effort to improve our understanding of the link between phonological differences and their phonetic realizations. We test the wide-spread assumption of phonological analyses that yer vowels are phonetically identical to their non-yer counterparts with measures of vowel duration, vowel quality and the patterns of coarticulation with surrounding sounds in both acoustic and articulatory data. Moreover, we compare these patterns with the patterns arising from the variation in speech rate. Our results provide tentative support for the hypothesis that yer vowels in Slovak are phonetically weaker than their non-yer counterparts. The relevance of this observation for the models of phonetics-phonology interface is discussed. Key words phonetics-phonology; acoustics; articulation; Slovak; yer vowels; speech rate
