Twitch's built-in caption feature isn't enough

Twitch has a closed-caption system, but it's limited: only some partners can use it, the API is fragile, mobile support is inconsistent, and viewers must manually enable captions. Most viewers never see them.

StreamTranslate adds captions directly to your video stream via OBS browser source. They appear on every viewer's screen, on every device, automatically — no Twitch caption pairing required.

Why captions matter on Twitch specifically

Mobile audiences are massive — ~50% of Twitch viewing is mobile, often with sound off
Deaf community is active on Twitch — DeafCheck, ASL Gaming Discords actively share captioned streamers
Twitch Mods often miss caption requests — automating with a tool is more reliable
Sponsor partnerships increasingly require accessibility — captioned streams qualify for more brand deals
Recommendation algorithm rewards retention — captions = more accessible = longer view duration = more recommendations

Captions for partner vs affiliate vs new streamers

Partner streamers — Twitch's built-in caption pairing works for some shows but is fragile. StreamTranslate is more reliable.

Affiliate streamers — built-in captions are mostly unavailable. StreamTranslate is the easiest way to add captions.

Brand-new streamers — same as affiliate. Adding captions early is a differentiator that small streamers can use to stand out.

Frequently asked

Do I need to be a Twitch partner to add captions?

No. StreamTranslate works for partner, affiliate, and brand-new streamers. We render captions directly into the video stream via OBS — independent of Twitch's caption system.

Will captions appear on Twitch mobile?

Yes. Because captions are part of the video (not a separate track), they appear on every viewer device including Twitch Mobile, embeds, and VODs.

Can I caption mid-stream without restarting?

Yes. Just add the browser source mid-stream — captions appear immediately. No need to restart OBS or end your stream.

Does this work for Just Chatting / IRL streams?

Yes — works for any Twitch category: gaming, Just Chatting, IRL, music, art. Whatever audio you have on stream gets captioned.

How accurate are the Twitch captions?

95%+ on clear English speech. Background music and multiple speakers can slightly lower accuracy — same as every captioning tool. For most streamers, accuracy is broadcast-grade.
