It is well known that experimental manipulations of real-time sensory feedback lead to sensorimotor adaptation: the planning of future movements takes account of the perturbed environment such that the performed movements partially or completely compensate for the manipulation. In speech, numerous studies have described auditory-motor adaptation to formant-shifted auditory feedback. Here, I will give an update on recent auditory-motor speech adaptation work from our own laboratory. In particular, I present new data regarding the effect on adaptation of delays in the auditory feedback signal, the possibility of using a habituation period to reduce the negative effects of such feedback delays, the relation between speech and limb motor learning, and our first attempt at developing a paradigm to dissociate explicit and implicit learning components in studies of speech adaptation. These new experimental data will be interpreted in the context of contemporary models of sensorimotor control.
