aContacts with a significant power increase (paired t test, FDR-corrected at q < 0.01) during speaking (SPK) and playback (PLY) are reported. Responses are identified as enhanced (ENH: speaking > playback) or suppressed (SUP: speaking < playback). FFR power was measured by first calculating the voice F0 contours of vowel sound vocalizations within individual trials and then extracting the ERBP around voice F0 (±5 Hz) in the second half of each vocalization epoch (400–800 ms). This time window was chosen so that the overlap between FFR and high gamma responses was minimal (see Fig. 2d). High gamma responses to voice were calculated as the mean ERBP between 75 and 150 Hz within 0–400 ms after voice onset. High gamma responses to pitch shift were calculated between 0 and 400 ms after pitch-shift onset.
