Facebook Live Subtitles & AI Translation

Facebook is still the world's largest video stage — millions of creators broadcast live every day, hundreds of millions watch, and Messenger handles billions of voice and video calls a month. Yet Facebook's native captioning is inconsistent: it depends on the creator turning on auto-generated captions, the broadcast language being supported, and the viewer being on a recent app version. Facebook live subtitles via Live Subtitles fix the gap. The app captions any Facebook audio playing on your Windows PC — Live broadcasts, Reels, Watch Parties, and Messenger calls — in 50+ languages, with no plugin and no creator setup required.

How to add live subtitles to Facebook in 3 steps

1. Download Live Subtitles from the Microsoft Store and launch the app.
2. Select "System Audio" as your audio source — captures whatever Facebook is playing in your browser or app.
3. Open Facebook Live, Watch Party, or Messenger — captions appear in a floating overlay you can move anywhere.

For Facebook Live viewers following global creators

The Facebook Live ecosystem is genuinely international. A small business in Vietnam might broadcast a product launch in Vietnamese; a fitness coach in Brazil might run a live workout in Portuguese; a journalist in Ukraine might deliver a real-time field report. Native auto-captions cover the popular cases but miss long-tail languages and often fail when the creator's audio is mixed with music or ambient noise.

Live Subtitles works around all of that. Because it captions audio at the system level, the language detection runs locally on what you actually hear — even if the creator never enabled captions, even if the broadcast is in a language Facebook does not auto-caption, Live Subtitles transcribes and translates it on the fly.

Messenger voice and video calls

Messenger is one of the world's most-used voice and video calling apps, often connecting families and friends across language boundaries. Native Messenger does not offer live captions on the desktop. Live Subtitles fills that gap with a captioning experience that needs no Facebook permission and no integration:

• One-on-one Messenger voice and video calls
• Messenger group calls and Rooms
• Calls placed from facebook.com or the Messenger desktop app
• Recorded voice messages played back from a Messenger thread

Family calls between native speakers of different languages are a particularly strong use case. A parent speaking Tagalog to a child living abroad, or grandparents conversing with grandchildren in another language, can read translations on screen while listening to the original voice — keeping the warmth of real speech without losing the meaning.

Watch Parties and group viewing in 50+ languages

Watch Party brings friends together to watch a video at the same time, with synchronized playback and a side voice chat. Live Subtitles captions both layers simultaneously — the video audio and the friends commenting over it — so a multilingual group can follow a foreign-language film together while still chatting in voice. Because it is a personal overlay, each participant can choose their own translation language independently.

Supported: 50+ recognition languages and 50+ translation target languages including Spanish, French, German, Italian, Japanese, Chinese, Korean, Russian, Arabic, Hindi, Portuguese, Polish, Dutch, Turkish, Vietnamese, Indonesian, Tagalog, and Ukrainian.

For creators who want a personal caption monitor

Creators broadcasting on Facebook Live often want to monitor what their own voice sounds like — pacing, clarity, whether their accent might confuse non-native viewers. Running Live Subtitles on the same PC gives you a live read-out of your own audio, which is invaluable for catching mumbled words or pacing issues in real time. Combined with the standard Facebook Live composer, it becomes a lightweight teleprompter feedback loop.
