^a Number and proportion of electrodes with significant phase–amplitude coupling (PAC), measured using the z-scored modulation index $(\mathrm{M}{\mathrm{I}}_z)$ or the GLM framework $(R_{\mathrm{PAC}})$ during either the baseline or voice-onset interval.

^b The mean change $(\mathrm{\Delta })$ in PAC ( $\mathrm{M}{\mathrm{I}}_z$ or $R_{\mathrm{PAC}}$) per electrode between the baseline and voice-onset intervals (i.e., baseline minus voice onset). preCG, precentral gyrus; postCG, postcentral gyrus; pIFG, posterior inferior frontal gyrus.
