Towards a Computational Articulatory Model of Spanish Phonology
نویسندگان
چکیده
Many aspects of Spanish phonology remain poorly described within feature-based frameworks, in part because it is not well understood to what extent phonological features are grounded in the phonetic domain. In this paper, we introduce a computational model of Spanish phonology based on articulatory primitives (Browman & Goldstein 1992) that is currently being developed as an extension of the Task Dynamics Application (TaDA: Saltzman & Munhall 1989; Nam et al. 2004). Under this model, lexical items are represented as molecules of coordinated gestures. Hypotheses about phonological representations are tested by comparing the results of articulatory and acoustic simulations against phonetic data acquired from Spanish speakers producing the same utterances. Two phenomena of particular interest in Spanish phonological theory that have been examined using this methodology are intervocalic stop lenition and liquid neutralization.

Phonological 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...

متن کاملSpanish complex onsets and the phonetics–phonology interface*
This study analyzes cross-dialectal phonetic variation in Spanish complex onsets in light of recent work on the phonetics–phonology interface. Two basic patterns of obstruent-rhotic cluster realization, vowel intrusion and coarticulation-induced rhotic assibilation, receive a phonetically-motivated explanation in terms of the temporal coordination of consonantal gestures, within the framework o...
متن کاملArticulatory Phonology, Task Dynamics and Computational Adequacy
This paper discusses articulatory phonology and task dynamics as potentially computationally adequate models which, together, might characterise speech production. The idea is introduced that, particularly at the task dynamic level, the object oriented computational paradigm is appropriate — this is a novel approach in speech production modelling. The paper concludes that articulatory phonology...
متن کاملGestural Alignment Constraints and Unstressed Vowel Devoicing in Andean Spanish
This paper applies the gestural alignment constraint schema proposed by Gafos (2002) to unstressed vowel devoicing in Andean Spanish. I will argue that this approach successfully addresses several characteristics identified in novel data from Cusco, Peru that depart from cross-linguistic trends in vowel devoicing and cannot be readily explained in terms of more traditional Articulatory Phonolog...
