Noise-vocoded speech becomes intelligible when preceded by the original utterance
Evidence
The main idea underlying the experimental paradigm was to take advantage of the priming effect to create two conditions in which the same speech stimuli were unintelligible and intelligible (condition a and c respectively; the prime is referred to as condition b ). Such an experiment has the potential to disentangle acoustic and phonetic models and to allow us to address the non-overlapping cortical activity encoded by their TRFs. — Dijk, Pim van, Physiology, Psychoacoustics and…, 4408
