Nicté's words speak for themselves. She explains the situation with a recent example.

We use YouTube as a video platform because YouTube offers subtitles easily. Translations are also available in other languages. Simply click on the subtitles button or press the c key (see picture below 1). Clicking on settings, other languages can be selected (see picture below 2). We want to make the videos usable for as many people as possible - even though we are aware that the translation is not always perfect.
