Engageli recordings (Playback room) editing and correcting auto generated captions.

Why?

The Government Digital Service (GDS) monitors public sector body web content for compliance with PSBAR (Public Sector Bodies Accessibility Regulations).

GDS interprets WCAG (Web Content Accessibility Guidelines) as requiring captions that accurately capture the meaning of the audio. “automatically-generated captions do not meet user needs or accessibility requirements, unless they are confirmed to be fully accurate. Usually they need significant editing.”

How? managing Recorded Captions:

After accessing the Recordings tab in the Engageli Admin Portal, you can manage captions (the subtitle or VTT files) using the options in the Download Subtitles column. 

NOTE you will have had to have previously enabled “Create caption vtt file when recording” setting for these to be created (see Engageli – adding closed captioning – instructor (teacher))

1. Access the Admin Portal: Log into the Engageli Admin Portal.
