Transcribe Audio & Video Files to Text On Youtube

Let us imagine you watched a video on youtube and you want the text version of it. Or you have audio lectures and want to make it a pdf file or a text version of it. What will you do?

There are so many transcription services online where you can hire people who can accurately transcribe the audio file into text. But it will cost you more money. The inexpensive option would be to take help of Youtube. A new feature on youtube now shows subtitles or captions for videos where the audio quality is decent and only one speaker is speaking at a time. Google uses Speech recognition technology and displays the speech as text from the video files. The text is stored in a hidden javascript. We can download this as a plain text file. It may not be as accurate as human transcription but if the audio quality is good then it converts perfectly.

When you see a CC button on a youtube video, then it is enabled for Subtitles. Google allows you to view the subtitles in various languages.
