Not everyone can understand fluent, spoken English. Non-native speakers can be sure they got the message right by reading the words – and this helps with language comprehension and acquisition whether on an ad-hoc basis for the general public or as part of a focused tuition programme.
Subtitles Promote Learning
Many parents complain that their kids watch too much TV or online video. With subtitles enabled, your children would be reading and learning the language while they watch their favourite shows.
And for anyone at all, subtitles means that, since the speech has been rendered into text, translations can much more easily be made into any language! Ultimately this would take your video content onto a truly global stage.
