| Research Abstract |
Speech comprehension is an indispensable human capability. It is important to detect its atypical development at an early stage for appropriate care and education. The present program aimed at detecting efficiently the brain activities called "evoked potentials" in association with detection and comprehension of speech, using a signal detection technique called "m-sequence modulation." It has been clarified with the technique that one-minute encephalogram with the naive Bayes classifier, or, three-minutes electroencephalogram with the conventional averaging contains sufficient information for the assessment of speech comprehension or of the specific response to human voice.
