Sensorimotor adaptation to feedback perturbations of vowel acoustics and its relation to perception

摘要: The role of auditory feedback in speech motor control was explored three related experiments. Experiment 1 investigated sensorimotor adaptation: the process by which speakers alter their production to compensate for perturbations feedback. When first formant frequency (F1) shifted heard subjects as they produced vowels consonant-vowel-consonant (CVC) words, subjects’ demonstrated compensatory shifts that were maintained when subsequently masked noise—evidence adaptation. 2 discrimination synthetic vowel stimuli differing F1 frequency, using same subjects. Those with more acute had compensated perturbation. 3 consisted simulations directions into velocities articulators model planning, showed can account key aspects compensation. In model, movement goals fo...
