An Approach Towards Generating Subtitles Automatically from Videos by Extracting Audio
Journal Title: GRD Journal for Engineering - Year 2018, Vol 3, Issue 5
Abstract
Videos are very important and helpful in our daily life for understanding and comprehend the information. With the help of videos user can gain the knowledge and spreads that knowledge to the other peoples. Hence, here it becomes important to make videos available to the people having auditory problems and even more for the people to remove the gaps of their native language. This all things are getting by using the subtitles for videos. There are several websites which are providing the subtitle files for the videos but not for all videos. Downloading subtitles from internet is a monotonous process. Hence to generate subtitles automatically with the help of software is the valid subject to research, this research paper resolves the problems mentioned above through the speech recognition technology. There are three models helps to generate subtitles for videos, Audio Extraction helps to extract audio from video and convert into .wav format for speech recognition process. Here 24% reduction rate has been achieved in the size of the video after the extraction. With the help of PocketSphinx speech recognition engine the .wav file get processed and the speech is get converted into text format and stored in .srt file for future use.
