Though closed captioning, transcripts, and audio descriptions are important to the creation of accessible video content, they are not the only accessibility features that are relevant to this medium. This chapter discusses some other important considerations for ensuring that videos are accessible for all users.
Sign Language Interpretation
Another option for improving accessibility in a video is providing sign language interpretation. There can be several reasons why this approach is preferable to captions or transcripts in at least some situations. First, in the case of American Sign Language (ASL), it can provide greater access than English captions or transcripts. ASL is its own separate natural language with a syntax and grammar different from English. This means that a D/deaf viewer may be fluent in ASL, but may not be as comfortable reading English captions, particularly at the speed required to follow a video. Second, including professional ASL interpretation can seamlessly convey tone and inflection in a way that is more difficult and awkward in captions. Finally, in some cases, particularly live streaming events, a professional ASL interpreter could provide more accessible real-time interpretation of the event than would live captioning, particularly if an automatic transcription or captioning tool was being used instead of a stenocaptioner.
When considering professional sign language interpretation, there are a few best practices to keep in mind:
* Even if auto-captions are available for an online event, it is helpful to offer a process for requesting sign language interpretation in advance. If this option is offered, it is important to have clear instructions on how to place such a request and a deadline that leaves enough time to schedule a professional interpreter.
* Following along from that first point, it is important to schedule an interpreter far in advance of the event so that it is possible to find a qualified interpreter; leaving this to the last minute prior to the event may result in inadequate services.
* If the event is presented live to an audience (for example, in an auditorium) in addition to being streamed for online viewing, ensure that the interpreter is clearly visible in the recording. When possible, it can be worth devoting a separate camera to the interpreter when the interpretation will be included in a...
