The subjects listened to segments from an audio book version of \"The Old Man and the Sea\" and their brain activity was recorded using a 128-channel ActiveTwo EEG system (BioSemi).\nThe stimuli folder contains .wav files of the presented audiobook segments as well as a .TextGrid file for each segment, containng the timing of  words and phonemes in that segment. The text grids were generated using the forced-alignment software Prosodylab-Aligner [^3] and inspected by eye. Each subject's folder contains one EEG-recording per audio segment and their starts are aligned (the EEG recordings are longer than the audio to a varying extent).  The recordings are unfiltered, unreferenced and sampled at 512 Hz.\n[^1]: Di Liberto, G. M., O’sullivan, J. A., & Lalor, E. C. (2015).
