Syllables resulted from nine sentences per speech rate (= 45 sentences) were summed and afterwards averaged across subjects (n = 18). Mean and standard deviation (in parenthesis) for the experimental (pre-SMA) and control (MOG) stimulation site. Slight inaccuracies of the sum (162 syllables for each rate or 810 syllables across all rates) of correct, silent, and incorrect events resulted from incorrect syllables more than substituted for the target.
