Speech Translatorとは
Translate any video, audio or livestream in real-time. Core features are completely free to use with no registration required!
This extension uses speech recognition technology, powered by Google or Microsoft, to convert speech from any source into text: the transcribing process. Then it translates the text from one language to another using your preferred translation service.
You can use it for:
- 🎞️ Transcribing and translating livestreams, videos, calls, etc.
- 🎤 Transcribing and translating your speech for a livestream overlay in OBS (for livestreamers)
- 🖥️ Real-time computer-assisted translation (basically human translation)
- 📖 Practicing language learning by dictating the text and reading the translation
- 🔠 Recording transcripts and translated captions for livestreams, calls, videos, or podcasts
- 👩💻 Extracting a text transcript to translate it later manually or with an advanced LLM
- 👂 Enhancing accessibility for people with hearing impairments
🔥 What’s New in Version 1.1

⚡ Version 1.0 Highlights
We have completely rebuilt the extension to make it easier to set up, alongside adding highly requested features:
- More Audio Sources: You can now capture audio directly from your Current Browser Tab, your entire Desktop, or your Input Audio Device (Microphone/VoiceMeeter).
- Translation Read Aloud (TTS): The extension can now read translations out loud, automatically lowering the volume of the original audio so you can hear clearly.
- Compact View Mode: A clean, subtitle-style display format with dynamically calculated display timing (perfect for OBS overlays).
- More Translation Engines: Choose from the world's leading translation services to get the best quality for your language.
- Offline Speech Recognition (Chrome Only): Process speech directly on your device with zero latency—no internet connection required!
- Dual Translation: Translate your speech into two different languages and display them alongside each other at the same time.
Free & Premium
While the core functionality of Speech Translator is completely free, we now offer Premium Upgrades for users who need advanced capabilities (like Desktop Capture, Offline Mode, or premium translation engines).
Privacy & Security
We take your data seriously. If you use the free version with default settings, all speech processing happens safely inside your browser or via secure Google APIs. If you create an account to use Premium translation engines, your transcribed text is only ever shared with the specific translation service you explicitly select. We never store your audio or translated text on our servers.
