In addition to making video content more accessible to viewers with impaired hearing, captioning can improve the effectiveness of video. Captions can:

• improve comprehension by native and foreign language speakers;
• help compensate for poor audio quality or background noise within a video;
• make video useful when a person is watching with the sound off or viewing in a noisy environment that obscures the sound; and,
• provide viewers with one way to search inside of videos.

Panopto has the ability to listen to your lecture videos and add ASR (automatic speech recognition) generated captions to your video. However, it is not foolproof, and it does not always do a great job in articulating scientific words. Because of these inconsistences, it is important to know how to edit the captions for accuracy.
