Improved intelligibility produces measurable cortical differences beyond mere acoustic responses

Evidence

In this experiment, the original speech (condition b ) was used as a prime for the second presentation of the noise-vocoded speech (condition c ). Also, the results obtained in condition b provide a baseline with which to compare with previous research (Di Liberto et al. 2015 ). Indeed, the main interest relies on the comparison between vocoded speech in the primed (a ) and in the non-primed (c ) conditions. In particular, we studied the standard trials, in which the difference between the primed and non-primed conditions can originate only in the EEG signal and it is related to an improved intelligibility (Fig. 2a ). — Dijk, Pim van, Physiology, Psychoacoustics and…, 4407
