Automatic closed caption generation from video files

The idea of speech recognition using computers and software is not new. However, for years, its rather low accuracy and constantly changing variables, such as a speaker’s accent, background noise, etc. has resulted in a low adoption rate (Challenges in adopting speech recognition, 2004), until a boo...
