Abstract(in English) | Recently, Brain-Computer Interfaces (BCI) are used for handicapped individuals such as patients that have difficulty in communicating. In this study, we explored the possibilities of non-invasive BCIs for speech identification. Based on electroencephalogram (EEG) and functional magnetic resonance imaging (fMRI), EEG cortical current signals were estimated using Variational Bayesian Multimodal Encephalo Graphy (VBMEG) method. The results of experiments with Japanese vowels /a/ and /i/ showed that classification accuracies might be increased when using anatomical-based functional region of interests (ROIs). |
