YouTube日本語音声翻訳・英語の動画を日本語で聞ける - EarDub 作成者: chris

EarDub is a YouTube dubbing extension for Firefox: an AI dubbing tool that translates and auto dubs foreign-language videos into your language in real time, with a natural AI voice-over. Install it, pick your language, and click the EarDub icon or the dub button at the bottom right of the video: the dub starts right away, so you can follow any foreign video with ease.

EarDub reads the video's captions, or the audio the player has already buffered when there are none, and translates with AI that follows the context: the title, the topic and the scene. Lines sound natural instead of machine-made, and the dub plays in step with the original sound. Nothing to upload or download, no waiting for the whole video: you hear the first lines within seconds. Listening is easier than following a video by reading subtitles.

• ★ 75 languages and 300+ AI voices, with regional accents
• ★ Works without captions: on YouTube and most sites where EarDub can read the video's sound
• ★ Built for courses: on Udemy and Coursera, EarDub moves on to the next lecture by itself
• ★ Translated by meaning: in a business talk, "they'll eat your lunch" becomes "they'll take your customers", not a line about food
• ★ Free plan: 30 minutes a day

How It Works
1. Open a video and click the EarDub button in the player (or press Shift+D).
2. Pick your language and voice.
3. Press play. Pause, skip ahead or go back, and the dub follows.

- Voices: male and female, with accents such as Indian or Irish English, Mexican or Argentine Spanish, Gulf or Levantine Arabic. Switch mid-video.
- Separate volume for the original sound and the dub.

FAQ
Does it work on my phone?
EarDub runs in Firefox on the desktop (version 140 or newer) and in Firefox for Android (version 142 or newer). iPhone and iPad aren't supported.

What can't it dub?
Copy-protected video (such as Netflix), live streams and some embedded players. All speakers share the one voice you pick.

How accurate is the translation?
It depends on the audio, the language pair and the topic. Turn on bilingual subtitles to check a line against the original.

Privacy
EarDub runs only when you click it: on YouTube by default, and on other sites after you allow them. Subtitles and the video title (or short pieces of audio when there are no subtitles) go to EarDub's servers for translation and speech. Audio isn't stored.
