What is SDH?

Subtitles for Deaf and Hard of Hearing (SDH) is intended for non-native speakers of the original language who have hearing impairments, helping them understand and enjoy the content of your audiovisual products.

SDH is the combination of Closed Captioning specifically made for deaf and hard of hearing people and Subtitling, which makes your media products accessible to foreign audiences. Thus, it integrates the benefits of both. SDH provides audiences with a rich viewing experience by rendering the dialogues, background noises, characters’ names, sound effects, etc. from the original audio to a foreign language.
