Research on the EEG Recognition for Brain-Computer Interface of Speech Based on DIVA Model

摘要：

　　Direction Into Velocities of Articulators(DIVA)model can be more accurately described as a mathematical model,it shows the role of the human brain involved in speech production and speech understanding by the region,it can simulate the pronunciation process and play a key role in speech BCI design.In order to realize the speech BCI system,we used wavelet packet decomposition and support vector machine(SVM)in EEG signal processing during the speech in this study according to the forecast of DIVA model and the conclusions of DIVA-related researches.Result shows that the eigenvector extracted by the method worked out fine in the classification of EEG signal,it provided a new way to design a speech-related BCI system.In addition,the conclusions of this study also proved the forecast of brain activation during the speech of DIVA model.
