We are now making and digesting more and more videos every day. And subtitles are a great way to make those videos more accessible to audiences around the world. But for a content creator, to make subtitles of a long duration video is a difficult process as he/she has to transcribe every word in the video and make the subtitles to be accurately synced with the video and audio.
In this case, it is of great importance to make use of automatic subtitle generator software to auto generate subtitles from videos. This kind of subtitle maker software does make it easier than ever before to generate subtitles from videos. In this tutorial, we will show you how to use the 6 best speech recognition software to do the task for you. Read on to find out how.
#1 Google Docs
I’m sure you are as surprised as everyone else when you see Google Docs in this section. Yes, it does subtitles with its speech-to-text transcription feature. And in facts, it’s actually very accurate compared to other software. However, there’s a bit of “DIYing” when you use this free auto subtitle generator software but the results will definitely excite you.
All in all, it’s quite easy to get started. Just follow the instructions below:
- Step 1. Go straight to Google documents then create a doc file.
- Step 2. Select Tools, then go to Voice typing.
- Step 3. After the Click to Speak window appears, you can select the
language and accent in the menu that’s just above the microphone icon.
After that, all you have to do is hit the microphone icon before you
play your audio or video.
As much as it’s very possible to use a microphone input to create subtitles, it might be affected by the surrounding noise. More to that, even if the surrounding is quiet, any extra sound input will decrease the accuracy of the results.

All you might have to do is to correct the names of people and a few technical terms. That’s it!
Another outstanding benefit of Otter is that you don’t have to keep watch of the transcribing process or even download any extra software. You will only need to upload your video to the site and it will automatically start the transcription process. Then after it is done, you will receive an email telling you that your subtitles are ready for review.
More importantly, you can create a free account on the Otter.ai website and each free account gets 600 minutes of subtitles every month. If you want more, you can pay $9.99 for an additional 6000 minutes.

YouTube will likely save you a lot of time in generating subtitles from videos as it uses its speech recognition technology to automatically create subtitles once you upload a new YouTube video that was recorded in English, French, Italian, German, Russian, Spanish, Dutch, Portuguese, Japanese, and Korean.
But you should upload videos that have clear audio of the speaker and no background noise, otherwise YouTube won’t let you add automatic subtitles.
