Generate closed captions from audio

Jan 16, 2019


Is there an option to generate closed captions from an audio file? The idea is similar to speech-to-text (STT), generating text from an audio file, where the text can be used. The source content is audio files that need to be listened and transcribed. The CC or STT option would be helpful and time saving. 

Thank you! :)

Hi Kiran!  The closed captions editor in Storyline 360 allows you to type in captions for your audio file, but doesn't automatically transcribe the audio into text on its own.  If your media clip doesn’t already have captions, the closed captions editor will automatically analyze the audio track to detect units of speech and add caption placeholders to the timeline that are synchronized with your content. All you need to do is type your captions in the placeholders.  Check out this page for more information on how to use the closed captions editor!

Storyline also supports SRT, VTT, SBV, and SUB files generated by third-party captioning services, such as YouTube, Amara, and 3PlayMedia.  Help on how to import caption files can be found here!  Let us know if you have any other questions!

This is my challenge today - I'm sad to discover that I'll be spending the rest of my day cutting and pasting from Notes that already exist in Storyline (!) to CC blocks that exist in Storyline, without any automation to make the process less painful.

If audio can be converted to text-to-speech (TTS), and if you can Generate Captions at the same time, why can't you do the conversion WITHOUT wiping out the original audio, and then keep the generated captions active when you delete the TTS track?  It seems like this would be a pretty elegant solution...

Okay... I figured out a way that's still time consuming, but MUCH less painful than copy/pasting from the script to Captions:

  1. Copy the real-voice audio track
  2. Convert the audio track to TTS
  3. Generate captions
  4. Export captions to a VTT (or similar) file
  5. Paste the original audio track back in
  6. Import the VTT captions file into the REAL voice track
  7. Delete the TTS track

It doesn't match up perfectly, but it's close enough (at least in my case) to work without re-sizing the captions. And once you get the hang of it, it takes about the same time to do an entire slide as it does to paste a couple of sentences into Captions.

Still... please put me down as a fervent supporter of the ability to generate captions from a narration audio track, and not just a TTS track.  :)

For now, you can import your VO files into Adobe Premiere (if you have Adobe Cloud) and use their transcribing and caption feature. Then, export the caption as SRT file and then import in Storyline. It's impressive how accurate the transcribe feature us. 

I'm pretty sure Articulate is working on getting this feature as other softwares have the capability.

What a pain !!!!!! For my last training courses, I absolutely had to add subtitles to many videos.
I planned to use Articulate's editor but I knew it would take me hours and even days.

So I spent some time trying to find a tool that would help me.

And after several hours of searching and testing I found it!
This little gem is called Checksub.

In my case, I had the script for some of my videos, but not all of them. 

With Checksub I was able to import my scripts and automatically transform them into subtitles. The synchronisation is perfect. This is when I love technology when it really saves you time. 

For videos without scripts, I was able to generate very good quality automatic subtitling. But I still had to make several changes. I did it with the Checksub online editor. It was really easy to use.

For the export you can generate an SRT file or burn-in the subtitles into the video. 

If you need to add subtitles to your videos I highly recommend you give it a try.
In any case, now I'm happy to not have to wait anymore for Articulate to develop this feature.
