On-demand lectures have become common in Japan. We are now developing a video re-editing tool for the purpose of utilizing the lecture videos used in such lectures. This tool is designed to shorten the playback time of lecture videos as much as possible without reducing the lecture content and to create digest videos by picking out the important parts from multiple lecture videos. In developing the tool, we conducted a survey of lecture videos actually used in on-demand lectures. We also confirmed that the time required for video playback can be reduced by about 30% by removing silent time. In addition, we conducted a basic investigation to see if it is possible to detect the parts of the lecture that the lecturer considers particularly important by using voice emotion recognition AI.
