Hearing clear speech afterwards makes a previously unintelligible noise-vocoded stream more intelligible.
Evidence
In order to alter the intelligibility of the speech, a method known as noise-vocoding was implemented (Shannon et al. 1995 ). This method filters the speech into a number of frequency-bands, and uses the amplitude envelope of each band to modulate band-limited noise. — Dijk, Pim van, Physiology, Psychoacoustics and…, 4376 (
