AI-Based Program Production Support Technology Automatic Transcription Support

摘要

Covid-19 has forced us to change our working habits and reassess our work-life balance, thus highlighting the importance of cutting down on long work hours and promoting the spread of telework. This series will introduce program production support technology that uses artificial intelligence (AI) to streamline, or otherwise improve, program production. One task in a program production studio is transcription work, in which the speech content of interviews, press conferences, and other video footage is written out as text to prepare broadcasting manuscripts and component materials. However, having a human listening to audio and then performing the transcription is a labor-intensive process that can take four to six times as long as the recorded time of the video footage. Also, in many cases, transcription requires the transcriber to play the video footage on special playback equipment at the broadcasting station, which limits the places where such work can be performed. Another point of consideration is that increasing amounts of video materials are requiring transcription now that such content can be exchanged over networks and because interviews can now be performed using simple devices such as smartphones.
