Brain computer interface (BCI) technologies, which enable direct communication between the brain and external devices, have been developed. However, with most of the BCI systems, users can only choose something from among what was prepared in advance. To develop more versatile BCI systems that can detect a user's intention or thoughts, the brain responses associated with verbal imagery need to be clarified. However, it was unclear how each parameter of the imagined sound reflected to the brain response associated with sound imagery. Therefore, in this study, we investigated relationships between the amplitude-envelope of the imagined sound and brain activity. First, the time-frequency features were extracted from brain responses for the imagery of speech sounds and pure tones with same envelopes with speech sounds using a continuous wavelet transform (CWT) and a principal component analysis (PCA). Finally, the discriminative accuracy was compared using a support vector Machine (SVM). |
