Production VIII-1 An articulatory modeling of Romanian diphthong alternations
Stefania Marin, Yale University
Paper File
  This paper presents an articulatory modeling of the alternation between Romanian diphthong [ea] and unstressed vowel [e], starting from the hypothesis that the representation of Romanian diphthongs is that of two vowels synchronously coordinated. Stimuli are created to examine the effect of this synchronous coordination in the absence of stress, and two perceptual experiments show that synchronously coordinated vowels [e] and [a] result in the percept of an [e]-like blended vowel – the same outcome as reported in Romanian phonological alternations.

  This study investigates the effects of varying prosodic boundary strength and lexical stress on domain initial /kl/ clusters in German by means of Electropalatography (EPG). Recordings of 7 subjects were analyzed using temporal and spatial parameters derived from the EPG data. Temporal and spatial parameters show that boundary effects are stronger for the first consonant while in the temporal domain stress affects the second consonant rather than the first. Overlap was found to be greater in unstressed position and at lower prosodic boundaries. Furthermore, /kl/ appears to be more susceptible to stress effects when not preceded by a boundary.

  Prosodic structure influences the fine-grained phonetic detail of German plosives. Phonetic characteristics that also cue the phonological fortis-lenis contrast are affected in different ways. Closure durations were longer at higher prosodic boundaries. There was also more glottal vibration in lenis plosives at smaller prosodic boundaries, which can be explained as an aerodynamic consequence of shorter closure duration. Voice onset time in lenis plosives was not affected by prosody. In contrast, VOT decreased at higher boundaries for fortis plosives, as did the maximal intensity of the release. These results demonstrate that effects of prosody on different phonetic cues can go into opposite directions, but are overall constrained by the need to maintain phonological contrasts. While prosodic effects on some cues are compatible with a 'fortition' account of prosodic strengthening or with a general feature enhancement explanation, the effects on others enhance paradigmatic contrasts only within a given prosodic position.
