From: Spontaneous variability predicts compensative motor response in vocal pitch control
Vowel differences in compensation ratio, amplitude, and variability. (A) Vocal responses against fo shifts in auditory feedback for /u/ vocalization (colored lines), those for /a/ trials as comparisons (gray lines). (B) The compensation ratio for /u/ vocalizations was generally smaller than that for /a/. (C, D) Correlation between the compensation ratio and variability of slow (C) or fast (D) components, respectively, for the /u/ vocalizations. (E) The voice amplitude of /u/ vowel was generally lower than that of /a/. (F, G) Voice amplitudes of /a/ (F) and /u/ (G) vowels did not show significant correlations with the compensation ratio. Asterisk (*) indicates significant correlation (p < 0.05).
