Why aren’t automatic captions (speech recognition) sufficient for a video shown in class?

Automatic captions do not meet caption quality or legal standards that apply to video captioning as a whole. Captions must relay the speaker’s exact words with correct spelling, punctuation, and grammar with 99% accuracy.Captions may not be paraphrased and must honor the original tone and intent of the speaker. Sounds, music, and other environmental noises must also appear.

For clarification on automated captions (speech recognition), please view this informational video regarding automated captions. A quick way to determine if the captions are acceptable is to check to see if there is proper punctuation and speaker identifiers.
