To the point, when asking “Is YouTube auto-generated captioning good enough?”, I would ask “Good enough for what?”




In short, when you’re dealing with unscripted dialogue, conversations, Q&A, lectures, etc., you need a professional transcription service to make the captions accessible. When dealing with a prepared statement or a script with no deviation, if the speaker speaks in a level monotone, with no “uhm” or “uhh”, you just might get away with a mechanical caption. But in such cases, you may already have access to the prepared statement or script, so making the transcription available as a separate file may just be enough.

Subject: [INSTTECH] Are Auto-Generated YouTube Captions Good Enough?


Like many institutions, we are wrestling with the question of captioning videos the college and faculty (through college-owned YouTube accounts) produces. A lot of the conversation is about amount of time and cost of services but there has been very little in terms of specific data. I began a time study by having multiple people follow a transcription process on several videos ranging from 2 to 22 minutes. The aim, of course, to provide some hard data in terms of time and costing for such a task.

The question was posed, "Is YouTube auto-generated captioning good enough?" Which really has two parts. 

  1. What is the acceptable error rate/accuracy rate for captioning generally?
  2. Is it defensible to use only YouTube captioning for videos?

I'd like to know if anyone has any experiences, knowledge, or data they could share. I'm also happy to share my time study results when it is complete; just let me know.
