Abstract(in English) | This study proposes a new silent speech BCI using both single-trial EEGs and speech signals. The EEGs segments, corresponding to the NS' components, are extracted from 19ch single-trial EEGs recorded during the janken task where the subject spoke in Japanese. After analyzing the EEG by ICA, a Kalman filter was learned from the reconstructed EEGs, equivalent to which dipoles were localized to the premotor cortex by ECDL, and spectrograms of the speech signals simultaneously recorded. The model spectrograms were predicted from single-trial EEGs recorded during the silent janken tasks. The preliminary results were that all the silent seven "rock" and twelve "paper" ICs were correctly recognized in terms of that the spectrograms approached the target regions of vowels. |
