The last ten years have been the witnesses of the emergence of any kind of video content. In the same time, certain individuals are deaf and occasionally cannot understand the meanings of such videos because there is not any text transcription available. Hence, it becomes important to make videos available to people who have these problems and even more to remove the gaps of native languages among them. This can be best done by providing subtitles of a video. However, downloading subtitles of any video from the internet is a tedious process. So, to generate subtitles automatically through the software itself and without the use of internet is the main concept of this paper. The objective of this paper is to provide an overview of generating subtitle on offline basis using CMUSPHINX4 java API. This system will first extract the audio, then recognize the extracted audio with CMUSPHINX4 java API. Later this system writes the recognized text to the text file with timestamp and saves it with .srt extension. Then, this .srt file can be opened in a media player to view the subtitles along with video
