Watch VTuber Streams in Your Language, Live
Stop waiting days for a translated clip. Whisperr translates a VTuber stream as it happens — floating subtitles over the stream on your phone, or clean tab capture on desktop. And if you are the VTuber, the same engine captions your stream for fans overseas.
How to watch a VTuber stream with live translation
Whisperr translates the stream audio, so it works on YouTube, Twitch, or wherever your oshi goes live — and on membership streams you are already watching.
- 1
Floating subtitles on iOS & Android
Open the Whisperr app, start transcription, turn on Floating Subtitles, then switch to YouTube or Twitch. Translated captions float over the stream while you watch chat and superchats as normal.
- 2
Tab capture on desktop
Watching in a browser? The Whisperr Web App and Chrome Extension capture the stream tab directly — digital audio with no room noise, which matters when a stream mixes game audio, BGM and voice.

Pick the stream language
Set the source language to Japanese, Korean, Chinese, or whatever your streamer speaks, and the target to yours. Whisperr keeps up with fast, unscripted talking rather than waiting for a caption track that never comes.
What users say
Whisperr review
“I love how easy Whisperr is to use and how it accurately understands and translates text and speech across different languages. It's so effective that even in scenarios where other tools might fail, Whisperr performs perfectly. Additionally, the ability to select languages for translation directly on a phone is fantastic. This feature helps us translate church services, ensuring everyone understands without missing anything important. The initial setup was straightforward, making it smooth to start using immediately.”
Fast Translations and a Clear, Easy-to-Read Layout
“It translated really fast, and the way the text appears on the screen—with its clear layout—is very easy to read.”
Whisperr Delivers Lightning-Fast, Highly Accurate Real-Time Translation
“The translation is extremely fast and accurate; after comparing several programs, I consider Whisperr to be the fastest and most accurate real-time translation app.”
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. Beyond that, 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. That setup makes studying feel fast and efficient, and it's easy to review sentence by sentence.”
Simple Real-Time Translation for Work
“I like best about Whisperr is that it feels simple and straightforward to use.”
Awesome
“This is very useful, extremely user-friendly, easy to use, and the recognition capability is very precise, with very fast speed. It should be the most accurate and fastest translation I've used so far.”
Easy to use
“Whisperr is easy to get started and no hassle at all. A great tool to learn languages and for travelling.”
Exceptional outcomes
“I attempted English to Hindi translation and achieved highly accurate results.”
Amazing
“Using it for Spanish to English and it’s amazing!”
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??”

Built for live streams
Keep up with the stream, not the clip channel
Fan translators do great work — but they publish hours or days later, and only for the moments they choose. This is the whole stream, live.
Live, not next week
Subtitles appear in about 0.2 seconds, so you follow jokes, reactions and superchat readings while they are actually happening.
Any streamer, any language
Japanese, Korean, Chinese, Indonesian and 100+ more — including streamers too small to have a clip channel translating them.
Floating subtitles
On iOS and Android the captions float over the streaming app, so you never leave the stream to read them.
Works on any platform
YouTube, Twitch, or a members-only stream — Whisperr translates the audio, so the platform and the paywall never matter.
Caption your own stream
VTubers can run the same engine in reverse: a browser source that captions your stream live for fans who do not speak your language.
Handles stream audio
Built for the fast speech, slang and background game audio of a live stream, not clean studio narration.
For VTubers: caption your own stream for overseas fans
The fastest way to grow an international audience is to let them understand you live.
Whisperr Broadcast Mode gives your stream a transparent overlay URL you drop into OBS as a browser source. Your speech is captioned and translated on screen, so viewers who do not speak your language can follow the stream itself instead of waiting for someone to clip and subtitle it later.
Because the captions are rendered into your video, they reach every platform you stream to at once, and every viewer sees them without installing anything or turning on a setting.
The overlay also parks a small QR code in a corner of the stream. Burned-in captions are one language for everyone; a fan who scans the code opens your live room on their phone and reads along in the language they choose instead.
Whisperr and fan translation are not the same thing
Clip channels and translation communities are the heart of international VTuber fandom, and a machine cannot replace them: fan translators localize jokes, catch references, and add the context that makes a moment land. Nothing here is a substitute for that work.
What Whisperr covers is the gap in between — the hours of stream that never get clipped, the streamers whose audience is too small for a dedicated translator, and the live moment itself, before anyone has had time to subtitle it. Use it to follow the stream as it airs, and keep watching the clips for the parts worth rewatching.
If you want a fully free option, Google Translate and Papago handle short phrases well, but they translate one utterance at a time and have no live-stream capture, floating subtitles, or continuous flow — you would be pausing the stream to type. Whisperr has a free tier, and unlimited real-time use is a flat annual fee with no per-minute metering.
