This project studies aspects of phoneme coproduction by applying the principles of two models of articulatory organization (DAC and Articulatory Phonology) and it extends their predictions to the analysis of tone coarticulation and to processes of sound change. The validity of these models will be investigated with respect to the mechanisms of coproduction and coarticulation during the production of consonant clusters in Catalan, English, and other languages, where the consonantsinvolve conflicting articulatory gestures. More specifically, we will investigate cases of assimilation and blending, as well the mechanisms of coordination between lingual activity and the activity of other articulatory structures. For this urpose, two main types of data will be obtained :movement data, gathered primarily with the use of an electromagnetometer (EMA) and aerodynamic data. The coarticulatory effects and the possible cases of blending between consecutive tonal contours will be dealt with in other experiments. We will also study the mechanisms of phonemic production that are responsible for he implementation of processes of sound change: syllable-final stop lenition and rhotasism as instances of gestural reduction; devoicing of syllable-final affricates and stops as instances of gestural stretching and overlap; processes of phonological neutralization as a solution for the coexistence of vowel or consonant phonemes on similar aritulatory tiers; the role of aerodynamic conditions in synchronic and diachronic processes of voicing and consonant assimilation.
