The subjective understanding of spoken language understanding is quantitatively evaluated by variations in oxygenated hemoglobin concentration measured by near-infrared spectroscopy. English listening comprehension tests consisting of two levels of difficulty were taken by 4 subjects during measurement. A correlation was found between subjective understanding and variations in oxygenated hemoglobin concentration.
