CerebroVoice: Bilingual sEEG Speech Dataset
iEEG ZarrStereo-electroencephalography (sEEG) recordings from two epilepsy patients performing bilingual speech tasks: reading Mandarin Chinese, English, and digits aloud. Signals were recorded at 1000 Hz with depth electrodes and are provided as preprocessed derivatives (low-frequency signal, high-gamma activity, and broadband signal), converted to BIDS-iEEG format. The dataset supports research on brain-to-speech decoding and bilingual speech neural activity.

2020 BCI competition, track 3
EEG ZarrEEG recordings from 15 participants performing imagined speech of five commands ("Hello", "Help me", "Stop", "Thank you", "Yes"), released for the 2020 BCI Competition Track 3. The data are split into training, validation and test runs to support machine-learning decoding of imagined speech for brain-computer interfaces. The dataset was converted from the original MATLAB files to BIDS-compliant EDF with trial annotations.

Imagined Speech EEG database — Spanish vowels and commands (Pressel et al. 2016)
EEG ZarrAn open-access EEG database of imagined speech recorded from 15 healthy Spanish-speaking adults. Participants imagined 11 classes, comprising 5 Spanish vowels and 6 directional commands, while 6-channel EEG was recorded at 1024 Hz. Trials lasted 4 s with a 3 s imagery window, and the data were bandpass filtered (2-45 Hz). The dataset supports brain-computer interface and imagined speech classification research and is redistributed in BIDS format via the MOABB collection.

PURSUE N400 Word Processing
EEG ZarrEEG dataset from the PURSUE project containing an N400 word processing task, recorded from participants at three primarily undergraduate institutions (Southern California, Massachusetts, and Virginia) in 2017 and 2018. The task design follows the ERP CORE paradigm. The dataset supports event-related potential research on semantic word processing.
