Abstract

This study aims at examining the production process of two syllables in a clash/ncontext and at describing the stress clash resolution strategies used in Catalan. First,/nwe carried out a perception experiment (500 target sentences) which proved a high/nlevel of confusion between stressed syllables in a clash environment and unstressed/nsyllables (camí net vs. caminet): this demonstrates the systematic destressing of the/nfirst syllable in the clash. Secondly, a production experiment was carried out with/ngroups of three sentences (576 utterances) in which always the same syllable was/ncompared (pi, vi) in three different prosodic conditions: clash context (vi blanc, pi/ngros), stressed syllable followed by unstressed syllable (vi blanquet, pi grosset),/nand unstressed syllable (vinet blanc, pinet gros). The results show that duration and/namplitude are not robust acoustic correlates of the perception of deaccenting;/nconversely, the F0 contour seems to be the main cue of destressing in such clash/ncontexts. Summing up, this article shows that Catalan uses a general strategy in/nstress clash resolution, the weakening or complete deaccenting of the first stress in/nthe clash (bon home, bon vi ), and furthermore, that this/nstrategy is directly reflected in the tonal organization of the sentence.
