(1) Use a Microphone
Kaltura, the multimedia platform built into eLearning@UNG (D2L), uses the audio track to translate the spoken word into text. A microphone will provide better audio quality, which translates into more accurate captioning.
Recording in a noisy environment, talking fast, or simply speaking too softly will result in closed captioning errors. DETI can ship a loaner headset with a built-in microphone to any UNG campus via interoffice mail.
(2) Watch the Video
When it’s completed, review the automatic closed captioning. An accuracy rate of 80 percent is not unusual, so expect to find errors.
(3) Fix it
Use Kaltura’s the built-in caption editor to correct errors.

Here’s a brief example from a math video:

Always check the closed captioning, regardless of the source.
