چکیده
In the case of paralysis with visual and tactile impairments, brain–computer interfaces (BCIs) based on auditory mental imagery paradigms are alternative methods for controlling external devices. This study demonstrates use a hybrid BCI via stimulation speech imagination assistive technology. The proposed using Thai vowel numeral stimulus patterns as well multi-loudspeaker position settings multi-command investigated. To avoid during resting periods, method is used to enable an audio stimulator. We observe classification efficiency BCIs from selected electroencephalogram channels algorithms. examine in presence background noise (speech). One command created speech-imagination paradigm. Four commands design experiment verify paradigm algorithms real-time processing. results show that average accuracy stimuli scatter without 72.2% 83.3%, respectively. under approximately two times lower than noise.
