Individuals with certain mental disorders, accidents, brain trauma, and vocal abuse can experience permanent or temporary speech impairments, that can significantly impact their quality of life and sometimes result in social isolation [1]. Brain–computer interfaces (BCIs) directly convert brain activities into computer control signals to establish connections with the external world [], which provides an alternative communication method for people suffering from severe neurological diseases [2, 3]. However, these approaches depend heavily on using complex network structures to improve the performance of EEG recognition and suffer from the deficit of training data. ZuCo Dataset. Reliable auditory-EEG decoders could facilitate the objective diagnosis of hearing disorders, or find applications in cognitively-steered hearing aids.

In this paper, we present our method of creating ArEEG_Chars, an EEG dataset that contains signals of Arabic characters. 15 (±15. Recently, due to the increasing availability of large EEG datasets, deep learning frameworks have been applied to the decoding and classification of EEG signals, which usually are associated with low signal to noise ratios (SNRs) and high dimensionality of the data. We have reviewed the models used in the literature to classify the EEG signals, and the available datasets for English. The first method directly decodes brain signals into a word, while the second method requires the use of an regulates and controls the autonomic nervous system to participate in emotional processes, directly utilizing the brain activities information (e. While previous studies have explored the use of imagined speech with semantically meaningful words for subject identification, most have relied on additional visual or auditory cues. However, unlike EEG pre-training methods, their effectiveness over more challenging group-level classification tasks, e. Later, the same group [22] increased the dataset by using 29 MCI and 32 HC and proposed an analysis of EEG signals based on supervised dictionary learning, called correlation-based Label consistent K-SVD (CLC-KSVD).
