How to watch Twitch streams with translated captions

Twitch streams have no subtitles and no translation, so a stream in a language you don’t speak is just noise. Echo Captions listens to the stream, turns the speech into text, translates it, and shows the result over the video about a third of a second behind the streamer. After a one-time install it takes one click.

What you need

• —Google Chrome, or a Chromium browser that installs extensions from the Chrome Web Store.
• —The Echo Captions extension — free to install.
• —Nothing else. No account for the first try, no API key, no settings.

Set-up in five steps

1. 01

   Install Echo Captions

   Add it from the Chrome Web Store. A short welcome page opens; you can close it or try the demo video.

2. 02

   Open the Twitch stream

   Any channel, any language. Kick streams work the same way.

3. 03

   Click the Echo button in the player

   It sits in the player’s control bar next to the native buttons. One click starts speech recognition and translation for that stream.

4. 04

   Check your language

   Echo picks it from your browser. Open the popup from the toolbar icon to change it — 14 languages are available.

5. 05

   Watch

   Subtitles appear over the stream. Turn on dual-language mode in the popup to see the original line above the translation.

What to expect from live translation

Captions run about 300 milliseconds behind the speech, which reads as simultaneous. Recognition works from the audio, so loud music, several people talking at once, or a bad microphone lower the accuracy — the same things that would make a human interpreter struggle. The translation is tuned for spoken language: gaming slang, fillers and names come out the way a person would say them, not as subtitle-ese.

Nothing is recorded. Audio is streamed in short chunks to the speech-to-text provider only while Echo is on, and isn’t stored on servers we control. Echo doesn’t track which streams you watch.

Free minutes and plans

Live translation runs continuously, so it uses your daily allowance faster than a regular video. As a guest you get about 5 minutes of translation a day — about 25 on your first day, so you can try a real stream. Signing in with Google raises that to about 10 minutes, free. If Twitch is where your evenings go, Echo Lite ($1.99 a month) covers about 1 hour of video a day and Echo Pro ($3.99) about 4 hours a day.

If something doesn’t work

• —No Echo button in the player: reload the page after installing or updating the extension.
• —Button is there, no captions: make sure the stream has speech — a music-only stream has nothing to transcribe — and check in the popup that today’s allowance isn’t used up.
• —Captions in the wrong language: open the popup and change the target language; it applies immediately.
• —Still stuck: the support page lists what to send us, and we usually reply within a day.
