Hearing-impaired students often need complementary technologies to assist them in understanding college lectures. Several universities already use PC captioning. Captionists sometime input unfamiliar technical terms and proper nouns in a lecture inaccurately. We call these words “input-difficult words (IDWs).” In this research, we evaluate performance-detecting IDWs by using real lectures from our university. We propose a method to automatically extract IDWs from lecture materials. We conducted an experiment to measure performance-detecting IDWs from lectures by changing the interpolation weight of the language model. In this experiment, we used four real lectures. A high F-measure of 0.889 was achieved.
