On our campus I would say we use a hybrid method. I have student workers who work on videos (and word, ppt, and pdf files) For videos they upload them to Youtube and set the videos to private and allow YouTube to autocaption them. I would say these days, and depending on the faculty member, the videos are coming in at 85-90% accuracy, the students then correct the captions, and add audio descriptions if possible, and if not possible they compile info per video which we share with the faculty member to potentially fix later. We then provide the faculty member with the caption file, a transcript file, and notes if it needs audio description. In doing this the cost is about $.41 a minute. The cheapest commercial option we have available comes in at $1.00 per minute.

Occasionally I hear about groups (on my campus and elsewhere) who are working to develop automated captioning and transcription tools.

I?d be curious to hear people?s thoughts on automated captioning, any success stories (or cautionary tales), cost/benefit analyses between automated and outsourced captioning, and especially what degree of accuracy would be sufficient (and is currently achievable) for such tools.

I look forward to your thoughts on this.
