FeedDub

FeedDub is a Chrome browser extension that, once installed, lets you turn on translated dubbing for videos on supported video platforms, so you can hear the translation in the player you're already familiar with. According to the official website, the dubbing stays in sync with the video: each spoken line lands on the matching timestamp of the original audio, so scrubbing the progress bar doesn't throw the dubbing off; the original audio stays in the background so you can still focus on the visuals. The dubbing is generated without relying on subtitles, and it supports five sites—YouTube, Netflix, Bilibili, TED, and Coursera—each with a dedicated adapter, offering 20 languages with one male and one female voice per language, switchable from the extension popup. Usage quota: you can use it without logging in, with 2 new videos per day for free and unlimited re-watching; signing in with Google gives you 3 days of unlimited use; after that it's $2 per month for unlimited use, or pay $2 for a single month only, with no auto-renewal. Pricing is a flat rate with no extra charges per video or per minute. On privacy, the official site states that FeedDub does not request Chrome's browsing history permission and only works on the five supported video platforms plus the services and media hosts it needs; the extension detects the local player and subtitles, and hovering over the microphone icon may pre-buffer the dubbing before you click.
