A realtime translator for everything playing in your browser
Streaming Translator turns any tab audio into live subtitles in your language — meetings, videos and livestreams, translated while people are still speaking.
A realtime translator converts speech into another language as it is being spoken, instead of after you paste text. Streaming Translator is a Chrome extension that listens to the current tab, transcribes the audio, translates it and shows subtitles within seconds — across 60+ languages.

Translation tools that make you wait are not enough
Copy-paste translators only work on text you already have, and recorded captions arrive after the moment has passed. A realtime translator works on live speech: it transcribes, translates and displays subtitles while the conversation is still going, so you can react in the moment.

How realtime translation works
Capture tab audio
The extension listens to the audio of the tab you choose — a meeting, a video or a livestream. Nothing is installed on the other side.
Transcribe and translate
Speech is transcribed and translated in one streaming pipeline, so the translation starts appearing while the sentence is still being spoken.
Read or listen
Subtitles overlay the page within a couple of seconds; turn on spoken narration to hear the translation read aloud.
Why Streaming Translator as your realtime translator?
Seconds, not minutes
Latency is typically a couple of seconds behind the speaker — fast enough to follow a live conversation and reply in the moment.
60+ languages, auto-detected
English, Chinese, Korean, Japanese, French, German, Spanish and more; the spoken language is detected automatically.
One extension for everything
The same tool covers meetings, videos and livestreams — no switching apps per use case.
Realtime translation FAQ
What is a realtime translator?
A realtime translator translates speech as it is being spoken, showing the result within seconds instead of waiting for a finished recording or pasted text. Streaming Translator does this for any audio playing in a Chrome tab.
How much delay does realtime translation have?
Typically a couple of seconds behind the speaker. The translation starts appearing while the sentence is still in progress.
Do I need a microphone?
No. Streaming Translator listens to the tab audio, not your microphone — it translates what you hear, not what you say.
How is it different from Google Translate?
Google Translate needs text or turn-based voice input. Streaming Translator translates continuous live audio — meetings, videos, streams — without copy-paste, and can read the translation aloud.
Is a realtime translator free to use?
You can start free: the trial includes 30 minutes of live translation, no credit card required. Paid plans start at $3/month.
