How to translate a YouTube live stream

Three ways to add live translated subtitles to YouTube — on phone or desktop.

  1. 1

    Floating subtitles on iOS & Android

    Open the Whisperr iOS or Android app, start transcription, enable Floating Subtitles, then switch to YouTube. Translated captions float on top of the video — no app switching while you watch.

  2. 2

    Browser tab capture (Web App, Mac or Windows desktop app)

    Open the stream in a browser tab and capture the tab audio with the Whisperr Web App, or use the Mac or Windows desktop app to capture your system audio. Best quality — digital audio with no background noise. Split the screen to read subtitles beside the video.

  3. 3

    Microphone / audio capture

    Watching on a TV or another device? Let Whisperr listen through your microphone and show translated subtitles in real time.

Whisperr vs YouTube auto-translated captions

YouTube can auto-translate captions on some videos — but live streams are a different story.

If YouTube auto-translate is greyed out or not working on a live stream, it is usually because the stream has no live captions to translate: live auto-captions exist for only a few source languages and depend on the channel’s settings. Whisperr skips captions entirely and translates the live audio itself.

What users say

Top-Notch Speech Recognition and Flashcard-Style Translations for Fast Study

“Whisperr's speech recognition and translation quality are both top-notch, and better than similar tools I've tried so far. As a Japanese learner, I especially like how Whisperr displays each sentence and its translation almost like flashcards, with a text-to-speech button for each one. Whisperr has removed a huge barrier to interacting with foreign-language speakers in real time, and to consuming video content that doesn't already have a translation.”

Worth hundreds of thousands of yen

“The same performance as other conversation translation apps. Those charge by the minute, but this one is apparently a one-time purchase, so the value for money is outstanding. Compared with about five similar apps, this one is the best on both performance and price. I wonder whether it was made by a Japanese developer??”
