Perturbation of stability patterns in syllable production

The aim of the present study is to capture the variation of continuous phonetic parameters associated with distinct phonological syllable organisations in Tashlhiyt Berber and Polish. In a first step, we investigate stability patterns for simple and complex onset coordination based on EMA data. In a second step, we test the degree of perturbation of the stability patterns under variation of phonetic parameters in a simulation task. While Tashlhiyt shows a clear simple onset parse across all tested conditions, the dominance of the preferred complex onset parse for Polish is perturbed when anchor variability is increased. We conclude that the degree of perturbation on a stability pattern differs within and across languages, a fact that has to be taken into account when capturing quantitative consequences of phonological syllable parses.
