Table 1.
Clusters of activation during speaking with spectrally (columns two to five) or temporally altered feedback (columns six to nine) compared to normal speaking (conjunction over consonant and vowel perturbations), small volume corrected for multiple comparison in literature-based ROIs at p < 0.05 with a cluster defining threshold of p < 0.001 (one-sided, paired t-test, n = 22 participants).
