How to Auto Generate Subtitles from Videos Online and Offline
We need subtitles when the characters of a movie or video speak in a language that we do not understand. Also, adding subtitles to instructional videos is a must to make the viewers understand about a specific process or product. But it is not easy to add subtitles to videos manually as it would require a lot of effort to make subtitles word by word and sentence by sentence, and add them in every scene. Moreover, the subtitles must sync with the audio and video to avoid confusion among the viewers.
However, now auto subtitle generator software is available that uses artificial intelligence to auto generate subtitles from videos. This kind of software does make it easier than ever before to generate subtitles from videos.
Let us take a look at some of the top best auto subtitle generator online and offline. And we will show you how to use them step by step.
#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 subtitle generator 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.
This is a fairly good speech recognition tool that will work as an effective subtitle text generator. 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.
This tool is easy to use and the output of it is amazing since Otter easily identifies the voices and weeds out the background noises. What’s more, the application easily picks up pauses and end of sentences. It also recognizes the difference between statements and questions. 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.
Just follow these 3 simple steps (click on each one to see the detailed instructions):
- Step 1. Import a video and let Otter start processing.
- Step 2. Once it has finished processing, you are able to edit and refine the transcript to improve its accuracy.
- Step 3. After editing, export your transcript as captions in SRT format.
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. So, you’d better remove the background sound from your video before uploading it. Although the accuracy of the subtitles is not always good if your video has low clarity audio, the automatic syncing feature is quite great. And thankfully, you are allowed to manually adjust the subtitles.

- Step 5. Press the Edit button to start adjusting and correcting the automatically generated subtitles.
- Step 6. Once you are finished, click on the Publish Edits.
