All negative modulatory effects were non-significant

Threshold for reporting for all contrasts was P < 0.001 and cluster-corrected P < 0.05 for FWE, clusters of minimum 3 voxels in both whole-brain or small-volume cluster-corrected levels. Only the strongest peaks are reported.

F0 fundamental frequency, HNR harmonic-to-noise ratio, SCG spectral center of gravity, L left, c/rSG caudo-rostral transition of the Sylvian gyrus, cSG/TP a region involving the ventralmost part of the caudal sylvian gyrus and the temporal pole, n.s. no significant clusters.
