SDH Subtitles

Describe every detail for hearing-impaired audiences with professional SDH subtitling services.

What Are SDH Subtitles?

Subtitles for the deaf and hard of hearing are intended for audiences that are unable to hear the audio in your video content. These captions do more than just display dialogue, they indicate who is speaking, the speaker’s tone, sound effects, music cues, and more.

US English SDH subtitles make your video content accessible to more than 11 million deaf and hard-of-hearing individuals in the US, while Multilingual SDH subtitles can expand your reach to more than 430 million people around the globe with disabling hearing loss.

The multimedia team at Wolfestone Group is dedicated to ensuring your hard-of-hearing and deaf viewers experience the same level of engagement as your hearing viewers. We manage 100% of your subtitling needs, including scripting, syncing, burning-in, and translating your SDH subtitles into 220+ languages. All of this is backed by the industry’s most rigorous standards of accuracy.

SDH Subtitles vs. Closed Captions: What's the Difference?

SDH and Closed Captions (CC) are both subtitle options that display dialogue and describe on-screen action for hard-of-hearing audiences.

The differences lie in their appearance, location, and encoding.

Closed captions appear as black stripes with white text. They are not often confined to the lower or top portion of the screen, so they can cover a significant part of the picture. This negatively affects the viewing experience.

SDH subtitles look like standard subtitles and are confined to the lower third of the screen. From a technical perspective, they also have more advanced encoding. SDH subtitles are supported through HDMI, while closed captions are not.
