Abstract	Purpose: The purpose of this study was to explore the relationship between feedback and feedforward control of articulation and voice by measuring reflexive and adaptive responses to first formant (F[subscript 1]) and fundamental frequency (f[subscript o]) perturbations. In addition, perception of F[subscript 1] and f[subscript o] perturbation was estimated using passive (listening) and active (speaking) just noticeable difference paradigms to assess the relation of auditory acuity to reflexive and adaptive responses. Method: Twenty healthy women produced single words and sustained vowels while the F[subscript 1] or f[subscript o] of their auditory feedback was suddenly and unpredictably perturbed to assess reflexive responses or gradually and predictably perturbed to assess adaptive responses. Results: Typical speakers' reflexive responses to sudden perturbation of F[subscript 1] were related to their adaptive responses to gradual perturbation of F[subscript 1]. Specifically, speakers with larger reflexive responses to sudden perturbation of F[subscript 1] had larger adaptive responses to gradual perturbation of F[subscript 1]. Furthermore, their reflexive responses to sudden perturbation of F[subscript 1] were associated with their passive auditory acuity to F[subscript 1] such that speakers with better auditory acuity to F[subscript 1] produced larger reflexive responses to sudden perturbations of F[subscript 1]. Typical speakers' adaptive responses to gradual perturbation of F[subscript 1] were not associated with their auditory acuity to F[subscript 1]. Speakers' reflexive and adaptive responses to perturbation of f[subscript o] were not related, nor were their responses related to either measure of auditory acuity to f[subscript o]. Conclusion: These findings indicate that there may be disparate feedback and feedforward control mechanisms for articulatory and vocal error correction based on auditory feedback. (As Provided).
