The present invention relates to a brainwave recognition system capable of outputting a user′s thought on a display of a computer in a character or a voice. According to the present invention, the brainwave recognition system comprises the steps of: storing a signal wave in a storage device to form a memory; executing a predetermined preprocessing process required for recognition in a step of inputting language of a brainwave outputted through an electrode; dividing the preprocessed brainwave signal into a mute section and a language brainwave section; extracting a parameter expressing a characteristic of the language brainwave for each section for a frame from a signal of the divided language brainwave section; extracting a frequency band exceeding a reference region set through the extracted parameter as a language brainwave signal; recognizing the language brainwave signal with respect to the outputter of the language brainwave; converting the characteristics of the brainwave, such as strength, pitch and the like, into a digital signal to be analyzed and comparing the digital signal with brainwave data stored in the memory so as to allow a processor to automatically determine a linguistic meaning included in the brainwave; and outputting the linguistic meaning included in the brainwave as a voice signal or a character to be displayed through a speaker or on a display.
