초록

본 연구는 e-sports 중계 콘텐츠 및 게임 스트리머 콘텐츠에 대한 청각장애인들의 시청 편의성을 위해 제공되는 자막의 서비스의 품질을 높이는 방안을 제시하기 위한 연구이다. 일반적으로 방송 콘텐츠의 자막 파일은 속기사에 의해 방송 중에 수동 작성되므로 원본 콘텐츠 대비 3~5초의 자막표시 지연이 필연적이다. 이에, 본 연구에서는, 음성인식 기술을 활용한 동기화 자동 보정 시스템의 구성을 제안하였다. 또한 이 시스템을 활용한 콘텐츠 적용실험을 진행하였으며 최종 결과로 자막 데이터의 동기화 오차 시간을 1초 이내로 줄일 수 있음을 확인 하였다.

This study is intended to suggest ways to improve the quality of the service of subtitles provided for the convenience of viewing for deaf people on e-sports broadcast content and game streamer content. Generally, subtitling files of broadcast content are manually written on air by stenographers, so a delay of 3 to 5 seconds is inevitable compared to the original content. Therefore, the present study proposed the formation of an automatic synchronization calibration system using speech recognition technology. In addition, a content application experiment using this system was conducted, and the final result confirmed that the time of synchronization error of subtitling data could be reduced to less than 1 second.
