Evaluation of Juncture Strength using Articulatory Synthesis of Prosodic Gestures and Functional Data Analysis

چکیده
Prosodic boundary gestures (pi-gestures) (Byrd & Saltzman, J. Phon., 2003) have been introduced to model the local slowing or lengthening of articulatory gestures in the vicinity of phrase boundaries. In this paper, pi-gestures are simulated within the TaDA task dynamics computational model and examined using functional data analysis (FDA) to evaluate articulatory lengthening in terms of underlying pi-gesture activation duration and strength from a realistic control model. A new derived variable of “deformation index” (area under FDA time-deformation functions) is shown to capture differences in π-gesture effect due to boundary strength.

Evaluation of prosodic juncture strength using functional data analysis
Prosodic structure has large effects on the temporal realization of speech via the shaping of articulatory events. It is important for speech scientists to be able to systematically quantify these prosodic effects on articulation in a way that is capable both of differentiating between the degree of prosodic lengthening associated with varying linguistic contexts and that is generalizable acros...
متن کاملPhrase boundary effects on the temporal kinematics of sequential tongue tip consonants.
This study evaluates the effects of phrase boundaries on the intra- and intergestural kinematic characteristics of blended gestures, i.e., overlapping gestures produced with a single articulator. The sequences examined are the juncture geminate [d(#)d], the sequence [d(#)z], and, for comparison, the singleton tongue tip gesture in [d(#)b]. This allows the investigation of the process of gestura...
متن کاملAt the Juncture of Prosody, Phonology, and Phonetics— the Interaction of Phrasal and Syllable Structure in Shaping the Timing of Consonant Gestures
The Laboratory Phonology research paradigm has established that abstract phonological structure has direct reflections in the spatiotemporal details of speech production. Past exploration of the complex relationship between linguistic structural properties and articulation has resulted in a softening of a severance between phonetics and phonology, which in recent years has begun to likewise enc...
متن کاملCoarticulation and prosodic hierarchy
This paper attempts to discuss the relationship between segmental coarticulation and prosodic structure in Mandarin Chinese. The discussion is mainly based on the EPG measurements to a set of phrases and short sentences produced in moderate speed. Main parameters measured in this study include (1) inter-gesture timing: temporal intervals overlapped between different articulatory gestures of V1#...
متن کاملA Kinematic Study of Prosodic Structure in Articulatory and Manual Gestures: Results from a Novel Method of Data Collection
The primary goal of this work is to examine prosodic structure as expressed concurrently through articulatory and manual gestures. Specifically, we investigated the effects of phrase-level prominence (Experiment 1) and of prosodic boundaries (Experiments 2 and 3) on the kinematic properties of oral constriction and manual gestures. The hypothesis guiding this work is that prosodic structure wil...
