SDH (Subtitles for the Deaf and Hard-of-Hearing)

SDH, or Subtitles for the Deaf and Hard-of-Hearing, are on-screen text displays that provide dialogue and important auditory information, such as sound effects and speaker identification. Designed to aid viewers who are deaf or hard of hearing, SDH conveys both spoken words and relevant sounds visually, ensuring they can fully understand and enjoy multimedia content. These subtitles are carefully synchronized with the audio and often include additional context, making media accessible to audiences with hearing impairments while maintaining clarity and accuracy.
