Technique G9:Creating captions for live synchronized media
About this Technique
This technique relates to:
- 1.2.4: Captions (Live) (Sufficient, together with G93: Providing open (always visible) captions)
- 1.2.4: Captions (Live) (Sufficient, together with G87: Providing closed captions)
- 1.2.4: Captions (Live) (Sufficient, together with G87: Providing closed captions using a more specific technique)
This technique applies to all technologies that present audio visual information.
Description
The objective of this technique is to allow users who cannot hear to be able to access real-time synchronized media broadcasts. It is more difficult to create accurate real-time captions because there is little time to correct mistakes or to listen a second time or consult someone to be sure the words are accurately reproduced. It is also harder to simplify or paraphrase information if it is flowing too quickly.
Real-time typing text entry techniques exist using stenographic and rapid typing technologies. Re-voicing speech-to-text (where a person listens to speech and then carefully re-voices it into a computer trained to their speech) is used today for telephone relay services and may be used in the future for captioning. Eventually speech-to-text with correction will be possible.
Examples
Example 1
A television studio uses a real-time captioning service to create captions for its evening news online.
Example 2
A user watches an online seminar on their mobile device, including captioning provided through the use of Communication Access Real-time Translation (CART). The captions provided also benefit in-person participants who need captioning and can view the information on their own device.
Tests
