Fourteen-channel EEG with Imagined Speech (FEIS) dataset

<pre>&gt;&lt;&gt; &gt;&lt;&gt; &gt;&lt;&gt; &gt;&lt;&gt; &gt;&lt;&gt; &gt;&lt;&gt; &gt;&lt;&gt; &gt;&lt;&gt; &gt;&lt;&gt; &gt;&lt;&gt; &gt;&lt;&gt; &gt;&lt;&gt; &gt;&lt;&gt; &gt;&lt;&gt; &gt;&lt;&gt; &gt;&lt;&gt; &gt;&lt;&gt; &gt;&lt;&gt; Welcome to the FEIS (Fourteen-channel EEG with Imagined Speech) dataset. &lt;&gt;&lt; &lt;&gt;&lt; &lt;&gt;&lt; &lt;&gt;&lt; &lt;&gt;&lt; &lt;&gt;&lt; &lt;&gt;&lt; &lt;&gt;&lt; &lt;&gt;&lt; &lt;&gt;&lt; &lt;&gt;&lt; &lt;&gt;&lt; &lt;&gt;&lt; &lt;&gt;&lt; &lt;&gt;&lt; &lt;&gt;&lt; &lt;&gt;&lt; &lt;&gt;&lt; The FEIS dataset comprises Emotiv EPOC+ [1] EEG recordings of: * 21 participants listening to, imagining speaking, and then actually speaking 16 English phonemes (see supplementary, below) * 2 participants listening to, imagining speaking, and then actually speaking 16 Chinese syllables (see supplementary, below) For replicability and for the benefit of further research, this dataset includes the complete experiment set-up, including participants&#39; recorded audio and &#39;flashcard&#39; screens for audio-visual prompts, Lua script and .mxs scenario for the OpenVibe [2] environment, as well as all Python scripts for the preparation and processing of data as used in the supporting studies (submitted in support of completion of the MSc Speech and Language Processing with the University of Edinburgh): * J. Clayton, &quot;Towards phone classification from imagined speech using a lightweight EEG brain-computer interface,&quot; M.Sc. dissertation, University of Edinburgh, Edinburgh, UK, 2019. * S. Wellington, &quot;An investigation into the possibilities and limitations of decoding heard, imagined and spoken phonemes using a low-density, mobile EEG headset,&quot; M.Sc. dissertation, University of Edinburgh, Edinburgh, UK, 2019. Each participant&#39;s data comprise 5 .csv files -- these are the &#39;raw&#39; (unprocessed) EEG recordings for the &#39;stimuli&#39;, &#39;articulators&#39; (see supplementary, below) &#39;thinking&#39;, &#39;speaking&#39; and &#39;resting&#39; phases per epoch for each trial -- alongside a &#39;full&#39; .csv file with the end-to-end experiment recording (for the benefit of calculating deltas). To guard against software deprecation or inaccessability, the full repository of open-source software used in the above studies is also included. We hope for the FEIS dataset to be of some utility for future researchers, due to the sparsity of similar open-access databases. As such, this dataset is made freely available for all academic and research purposes (non-profit). &gt;&lt;&gt; &gt;&lt;&gt; &gt;&lt;&gt; &gt;&lt;&gt; &gt;&lt;&gt; &gt;&lt;&gt; &gt;&lt;&gt; &gt;&lt;&gt; &gt;&lt;&gt; &gt;&lt;&gt; &gt;&lt;&gt; &gt;&lt;&gt; &gt;&lt;&gt; &gt;&lt;&gt; &gt;&lt;&gt; &gt;&lt;&gt; &gt;&lt;&gt; &gt;&lt;&gt; REFERENCING &lt;&gt;&lt; &lt;&gt;&lt; &lt;&gt;&lt; &lt;&gt;&lt; &lt;&gt;&lt; &lt;&gt;&lt; &lt;&gt;&lt; &lt;&gt;&lt; &lt;&gt;&lt; &lt;&gt;&lt; &lt;&gt;&lt; &lt;&gt;&lt; &lt;&gt;&lt; &lt;&gt;&lt; &lt;&gt;&lt; &lt;&gt;&lt; &lt;&gt;&lt; &lt;&gt;&lt; If you use the FEIS dataset, please reference: * S.

VocalMind: A Stereotactic EEG Dataset for Vocalized, Mimed, and Imagined Speech in Tonal Language

<p>&nbsp;Speech BCIs based on implanted electrodes hold significant promise for enhancing spoken communication through high temporal resolution and invasive neural sensing. Despite the potential, acquiring such data is challenging due to its invasive nature, and publicly available datasets, particularly for tonal languages, are limited. In this study, we introduce <em>VocalMind</em>, a stereotactic electroencephalography (sEEG) dataset focused on Mandarin Chinese, a tonal language. This dataset includes sEEG-speech parallel recordings from three distinct speech modes, namely vocalized speech, mimed speech, and imagined speech, at both word and sentence levels, totaling over one hour of intracranial neural recordings related to speech production. This paper also presents a baseline model as the reference model for future studies, at the same time, ensuring the integrity of the dataset. The diversity of tasks and the substantial data volume provide a valuable resource for developing advanced algorithms for speech decoding, thereby advancing BCI research for spoken communication.</p>
