Dubingo is a free AI live dubbing extension for Firefox that translates and voices browser audio in real time.

Powered by Google's Gemini Live AI, Dubingo turns spoken audio into natural, expressive voice translation with very low latency, helping you follow foreign content and conversations as they happen.

🌍 100% Free. 80+ Languages. Any Browser Tab.

⚡ LIVE DUBBING, NOT DELAYED SUBTITLES

Traditional translation tools often make you wait for speech to be transcribed, translated, and displayed as text.

Dubingo works differently.

Audio is processed through Gemini's live speech model to produce continuous voice translation with very low latency, keeping you close to the original conversation.

No waiting for translated videos.
No downloading files.
No generating subtitles first.

Just play and listen.

🌍 80+ LANGUAGES

Dubingo supports live dubbing across 80+ languages, making content from around the world accessible in your own language.

Dub from virtually any supported source language into languages including:

English, Persian (فارسی), Spanish, French, German, Arabic, Turkish, Russian, Japanese, Chinese, Italian, Portuguese, Korean, Hindi, Dutch, Polish, Ukrainian, Vietnamese, Indonesian, Swedish, Greek, Hebrew, Thai, and many more.

🎭 NATURAL AI VOICES

Dubingo is designed to sound natural, not robotic.

Choose different voice styles depending on what you're watching or listening to:

• Conversational for videos, podcasts, and everyday content
• Formal / Academic for lectures, courses, and professional content
• Friendly for a more relaxed listening experience

🎚 KEEP THE ORIGINAL AUDIO

Want to hear the original speaker too?

Dubingo's audio mixer lets you control the balance between the original audio and the translated voice.

Keep background music, sound effects, and the original speaker quietly in the background while the translated voice stays clear.

💬 LIVE SUBTITLES

Prefer reading while listening?

Enable Dubingo's customizable floating subtitle overlay and follow the translated speech directly on top of the video.

• Glass Blur
• Cinema Yellow
• Solid
