While 90 or 95% accuracy may seem to be “good enough,” the fact is that the intelligibility of captions drops precipitously with error rates of higher than 3% ( see our research). However, even in the best cases, transcription using speech recognition typically yields results in the low 90 percent accuracy range.
Speech recognition does hold great promise, and it continues to get better over time.
CLEAR CAPTION SOFTWARE
Closed Captioning Costs Using Speech Recognitionįor many video producers, finding software that could automatically transcribe and caption video in a few minutes would be like finding the holy grail. There are a few methods that captioning companies can use to hit these low cost thresholds: 1) using speech recognition, 2) using crowd-sourcing, or 3) using very inexpensive offshore labor. Which inevitably raises the question: could the cost of closed captioning be even cheaper? In this world of technology and global outsourcing, shouldn’t there be a way to bring down the cost of captioning to almost zero?Īnd indeed, there is a new crop of closed captioning companies that are attempting to do just that, with several companies advertising closed captioning pricing as low as $1.00 per minute. They do the math, multiplying the number of minutes of video by the cost per minute of closed captioning, and suddenly they have a very large new budget line item that they hadn’t anticipated. However, as video publishers that are new to closed captioning come into the fold and they start to add up the cost of captioning the terabytes of video that they plan to produce, it’s easy for purchasers to become overwhelmed by the potential cost of closed captioning. We know that our customers are grateful for these cost benefits, and that they appreciate our quick turnaround times (time is money, after all). AST has brought down the average cost of closed captioning to around $3 per minute or less in many cases, and it is safe to say that we have saved publishers, educators, government agencies, and other producers of educational video tens of millions of dollars over the last 10 years.
CLEAR CAPTION MANUAL
Prior to the introduction of AST, video publishers would often pay more than $10 per minute of video for closed captioning, and would often wait two weeks or more to get back the results of a very manual process. We’ve worked with thousands of organizations over the past 10 years, and a few weeks ago we hit another milestone: we delivered our five millionth caption file. By bringing down closed captioning costs, we make it easier for companies and organizations to make their video accessible to everyone.
AST was founded with the goal of making the process of captioning video faster and more affordable.
