Closed Captioning

Closed captions allow deaf and hard of hearing viewers to have a complete understanding of the content they are watching. Unlike subtitles, they display all audible information in the original work, including dialog, non-verbal vocalization such as laughter, crying, etc., as well as descriptions of sound effects and music. Often referred to as CC, closed captions are an accessibility solution rather than a localization service. According to the World Health Organization, there are 466 million people worldwide with a hearing impairment, including 36 million children. As a matter of equity and fairness, closed captions are increasingly a legal requirement for broadcasters and online streaming platforms so that this important audience is properly served.

Closed Captions that Make Sense

SPG’s global network of linguists understand the unique challenges of presenting captions. It takes specialized training to capture and express relevant audio information while maintaining synchronization with visuals. To ensure the absolute highest quality, SPG requires a second caption specialist to review the text for accuracy and flow. A separate editor then reviews the placement of the captions to ensure the text doesn’t obscure important elements in the video.

Technical Expertise

SPG has extensive experience with the style and formatting requirements of all major broadcasters and streaming platforms. Our team of experts guide our clients through the entire process and help them select the ideal format (SCC, WebVTT, AFF, etc.) based on the final usage and platform(s) for the closed captions.
