Subtitling for people who are D/deaf or hard-of-hearing (SDH)

Subtitles for an audience that is D/deaf or hard-of-hearing (SDH) are displayed in the lower section of an audio-visual product. They describe what is on the soundtrack in a condensed written form. Unlike interlingual subtitles, they are usually not translations from one language to another. Instead, they are translations from one mode to another, the target mode being the written form. Subtitles for the D/deaf or hard-of-hearing are intended, as implied in the name, for a specific target group, i.e., people who have limited or no access to the soundtrack of audio-visual media. The change of mode is intended to compensate for the loss of information on a verbal, nonverbal and paraverbal level.
