The 533 source files are mirrored without modifying their contents or source
directory layout. This dataset card and the checksum manifest are the only
mirror-added files. The snapshot totals 22,025,659,310 bytes (20.51 GiB).

## Dataset summary

UGR-MINDVOICE is a multimodal corpus of 64-channel EEG sampled at 1,000 Hz and
synchronized audio from 15 native Iberian Spanish speakers across 22 sessions.
Each session includes overt and covert speech in alternating mini-blocks.
Stimuli cover all Spanish phonemes through 95 consonant-vowel syllables, 60
words balanced across six semantic categories and lexical frequencies, and 30
pseudowords. Overt productions include synchronized acoustic recordings.

The `Data/` directory is organized according to BIDS and contains the
participant and recording data. `Materials/` contains the stimuli and
experiment files, while `Analyses and Results/` contains analysis
documentation.

## Human-participant data

These are human EEG and voice recordings. Users are responsible for applicable
institutional, ethical, and legal requirements and must not attempt to identify
participants.
