Mechanisms of sensorimotor adaptation in a hierarchical state feedback control model of speech
Fig 6
Within-utterance data during online compensation response.
Yellow shaded area indicates time steps with the 100 Hz up-shift perturbation in F1. Left: F1 decreased across the time steps in response to the unpredictable perturbation. Middle: The compensatory response was also observed in the articulatory state estimate (gray dots) and its true state (green lines) expressed in the Maeda unit (M). Right: Despite the changes in the articulatory state, the task state estimate remained near the task target.
