This work exploited coarticulation and loud speech as natural sources of perturbation in order to determine whether articulatory covariation (motor equivalent behavior) can be observed in speech that is not artificially perturbed. Articulatory analyses of jaw and tongue movement in the production of alveolar consonants by German speakers were performed. The sibilant /s/ shows virtually no articulatory covariation under the influence of natural perturbations, whereas other alveolar consonants show more obvious compensatory behavior. Our conclusion is that an effect of natural sources of perturbation is noticable, but sounds are affected to different degrees.
