Fig. 2. Interaction between dichotic condition (left/right) and type of feedback alteration (spectral/temporal).

Values represent produced speech features averaged across early and late ramp, hold and after effect phase separately for spectral (orange) and temporal (blue) feedback alterations presented to the left (square) and right (triangle) hemisphere, respectively. Produced speech features are relative to baseline, smaller values indicate greater compensation. Data present estimated means± model derived standard errors that account for between-subject variability (n_spectral = 18 participants, n_temporal = 18). Individual raw values are plotted in the background (yellow: spectral perturbation vowel n = 9, orange: spectral perturbation consonant n = 9, light blue: temporal perturbation vowel n = 9, dark blue: temporal perturbation fricative n = 9). Source data are provided as a Source Data file.
