Voice Translator

Voice Translator dubs videos that already have subtitles into your language — with a natural, synced voice. It's 100% free: no account, no sign-up, and no API key.

HOW IT WORKS
• Open a video that has captions (YouTube, Bilibili, and other sites with subtitles).
• Click the button in the player — or the floating button — pick your language, and press Translate.
• The extension reads the captions, translates them, and plays a voice in your language synced to the video, with optional bilingual subtitles.
• Re-watching is instant and free (dubbed audio is cached locally).

FREE, NO KEY
• Translation: Google Translate, Microsoft Translator, or fully on-device (Chrome built-in).
• Voice: Microsoft Edge neural voices (free) or your browser's built-in voice.
• No OpenAI key, no account, no paid tiers.

WHAT'S SUPPORTED
• Videos that have subtitles/captions. No subtitles? You can import an SRT/VTT file.
• Live streams and videos without any captions are not supported in this version.

PICK ONCE
• Set your target language once — it's remembered for every video.
• Choose a male or female voice and balance the original/dubbing volume.

PRIVACY
• Everything runs in your browser. We have no servers and collect no data.
• Caption text is sent only to the free translation/voice service you choose — or kept fully on-device if you pick the on-device engine and browser voice.
