•Speech cues above and below phase locking evoke different MGB activity•Speech envelope cues in quiet are reflected in likely MGB amplitudes•Extended high-frequency thresholds are reflected in MGB delay related to speech cues.•MGB delay may predict speech recognition in quiet and noise independent o...
