a–c, Predicted BOLD signal for three contrasts: linear correlation between BOLD signal and intelligibility (a), a differential response to the three forms of distortion (b), and an elevated response to all forms of distorted speech (c), compared with clear speech and signal-correlated noise. Open triangles, Signal-correlated noise; circles, segmented speech;x symbols, vocoded speech; squares, speech in noise; filled triangles, normal speech.
