The advantages of using subtitles in your Twitch streamings are:

  • Improve the viewing experience for all viewers. Most significantly for those who are hearing impaired. Or watch the content without sound because they are in a public place, in the silence of the night or in any other situation in which they choose to be silent viewers.
  • Give accessibility to the content. Closed captioning makes it possible for viewers worldwide to understand the content of materials produced in non-native languages.
  • Encourage more significant interaction with the content. Subtitles help everyone to grasp better, understand and respond to the content because, in addition to the auditory experience, they are complemented by the visual element.

Today there are new social viewing styles; streamers, for example, prefer to watch with subtitles. Understanding these new realities will allow you to reach a wider audience, be inclusive, and your content will be much more professional and engaging.
