On the articulatory bases of prominence in Italian
نویسندگان
چکیده
This study reports the first results of a research aimed to investigate how segmental variation is conditioned by prosody in Italian, by examining the acoustic and articulatory properties of syllables that are prominent at different levels of the prosodic hierarchy. We examined lip movement kinematics of unstressed, stressed and nuclearly accented syllables in order to understand the kinematic characteristics of accent-induced articulatory strenghthening. The kinematic results are then interpreted within a Task Dynamics model to evaluate how prosodically-driven variation can be accounted for by a particular dynamical parameter setting in a mass-spring gestural model.

Relations between prominence and articulatory-prosodic cues in emotional speech
This study investigates the relations between the degree of prominence and articulatory-prosodic cues in emotional speech. In particular, this study considers articulatory parameters driven from the Converter/Distributor (C/D) model. The goal is to obtain a better understanding of the link among syllable magnitude in the C/D model, the empirical way to measure it in literature, and syllable-lev...

We examine the functional coupling between articulatory characteristics of prominence, such as articulator speed, and its acoustic characteristics, such as F0 and acoustic energy, for content words (nouns) and function words (e.g., articles, prepositions and conjunctions) using real-time magnetic resonance imaging data. We use Granger causality ideas to test the degree and direction of causal i...
متن کاملBridging articulation and perception: The C/D model and contrastive emphasis
This paper compares prominence that listeners perceive with actual articulatory prominence. We calculated phrasal boundaries from articulatory patterns using an algorithm of the C/D model, and compared those calculated boundaries with perceived boundaries. The jaw displacements, measures of prominence, were measured using EMA; articulatory boundaries were derived from a C/D model algorithm. The...
متن کاملPhonological Awareness Impact on Articulatory Accuracy of the Spanish Liquid [r] in Japanese FL Learners of Spanish
Foreign language learners tend to avoid phonological difficulties and simply transfer sounds whether from their L1 or any pre-existing L2. Phonological awareness (PA) gives students an active role in understanding their own potential in improving pronunciation through several methods. However, such methods are likely to be restricted to only passive learning methods, such as repetition, reading...
