Supported Platforms

Provides closed captioning via Google Cloud Speech Recognition API as a standalone OBS plugin. It's fully optional to viewers and uses Twitch's built in caption support which works on livestreams and in VODs on PC, Android and iOS, no Twitch extension required.

Features:
  • Captions only when the microphone source is unmuted and active to ensure safety
  • Works live and in VODs, no Twitch extension required
  • Completely optional for viewers
  • Supports OBS delay
  • Requires no extra tools or website open
  • Supports many common languages with western character sets
Notes:
  • The caption delay is usually less than half a second and should not be noticeable to viewers.
  • The plugin only captions the selected audio source when it's not muted and when it's used on the current active scene to ensure safety and avoid any captioning when the mic is muted for the stream.
  • Video players with caption support like VLC can also show captions on downloaded VODs if enabled.
  • Only tested on Twitch.tv, other streaming services with native caption support might work but not very likely.
  • You can enable and disable the caption preview dock in OBS under View -> Docks -> Captions
  • The quality of Google's Speech Recognition heavily depends on the speaker and what is being said. The results are usually be pretty good in normal conversational settings like talking to chat but the recognition quality can go down noticeably when using ingame terms or other specialized vocabulary or during hectic speaking.
Captions should be off by default for most viewers but Twitch does sometimes have them enabled for some viewers for unknown reasons so occasionally some will be confused on how to turn them off and might need it explained.
  • On PC viewers can turn captions on and off using the CC button on the bottom right of the player.
  • On iOS it's a system wide setting: Settings -> General -> Accessibility -> Subtitles & Captioning -> Closed Captions + SHD
    • If it's already off but viewers still see captions they have to turn it on and off again (appears to be a bug on some iOS versions)
  • On Android it's Closed Captions under the player settings options right beneath the quality selection. The option will only show up once the streamer has talked.
Requires OBS 23.2.1 (released June 15th 2019) or newer!

GREAT, I AM IMPRESSED. Getting the o/p into a source would be killer.
This plugin is really awesome. I used it for instant open caption for recording my lecture class. With only using Google API, it has many possibilities to detect more language. Best for those who hate to take notes and just let technology do it for you.

However, I can't install this plugin on Linux. (im a noob). I'm trying to find your contact so I can DM, if you see this, please leave help me. By the way, I am using Zorin OS 15, it should be Ubuntu based distro. It would be appreciated if you could assist me. Here's my discord: RIcohLA#3915
Great plugin, but why doesn't it allow it's output yo become a render-able resource of it's own. I want to see the CC output in my OBS stream, right from the captioning plugin. Do-able?
Works well during texting, happy it can save SRT of the result.
Great plugin, though I suppose improvement of the voice to text recognition would be on google side, right?
I'm french, I'm using the french (Canada) because funnily enough, I find it working better than the french (France).
I wish it was built in to obs - this is my most recommended plugin inside of OBS. Having accessibility is so important - I've been using this for more than a year
It works marvelously!
One feature which I really really want for the next updates: enabling text editing in the preview window / dock.
I think this is very important for some application such as live meeting because sometimes there was a word that make horrible means, since Google's recognition not always 100% correct.
Great plugin easy implementation and checks all my boxes might not be 100% correct all the time but that's to be expected :) It seems to get better from day to day.
Plugin works fine on Mac, but I no longer stream with it.

Any plans to find a way for it to work with the AMD Hardware encoder on Windows? I can tell that it's hearing my voice but it doesn't get sent to my streams.

Thanks for providing this, hope we can get that resolved though. Great resource as accessibility is a must!
For anyone wanting to add closed captioning to their stream, this is the absolute best way to go about it. No extensions, nothing cluttering your screen. The speech-to-text gets things right almost all of the time, barring things like usernames in chat. The best part is, since the closed captions are embedded with the stream, they save to the VOD, which doesn't happen with extensions!
