Previous studies have demonstrated a wide range in individuals’ compensations in response to real-time alterations of the auditory feedback of both pitch and formant frequencies. One potential source of this variability may be individual differences in the relative weighting of auditory and somatosensory feedback. The present study examined this variability by comparing individuals’ compensations during two perturbation conditions:
a pitch shift (+200 cents) and a formant shift (F1 +200 Hz, F2 -250 Hz). While no significant correlation was found between the two perturbation conditions, a modest correlation between compensations in pitch and formant frequency was observed
within the pitch perturbation condition.
