Speech Modality Classification with Cortical EEG Signals

The present work aimed to classify three speech modalities (i.e., spoken speech, intended speech and imagined speech) by using their corresponding cortical EEG signals. Eleven participants were recruited to take part in the experiments to produce 70 Mandarin-Chinese monosyllables in different speech modalities. The EEG signals were recorded during the experiments and processed by discrete wavelet ...
