Over the weekend, YouTube introduced a new feature to help make captioned or subtitled videos more accessible to international users. The new system uses machine translation to convert any of these videos into your language of choice in real time.
To access this feature, users simply need to turn it on from the lower-right corner of the player. From there, they can use a simple drop-down menu to pick which language into which they want the video translated. Unfortunately, YouTube won’t remember a user’s translation choices from one video to the next, but this seems like a feature that could be added down the line.
