Consistency influences altered auditory feedback processing

Abstract
Previous research on the effect of perturbed auditory feedback in speech production has focused on two types of responses. In the short term, speakers generate compensatory motor commands in response to unexpected perturbations. In the longer term, speakers adapt feedforward motor programs in response to feedback perturbations, in order to avoid future errors. The current study investigated the relation between these two types of responses to altered auditory feedback. Specifically, it was hypothesized that consistency in previous feedback perturbations would influence whether speakers adapt their feedforward motor programs. In an altered auditory feedback paradigm, formant perturbations were applied either across all trials (the consistent condition) or only to some trials while the others remained unperturbed (the inconsistent condition). The results showed that speakers’ responses were affected by feedback consistency, with stronger speech changes in the consistent condition compared to the inconsistent condition. Current models of speech-motor control can explain this consistency effect. However, the data also suggest compensation and adaptation are distinct processes, which is not in line with all current models.
