This article answers the all-important accuracy question.
So you'd like to know just how accurate Caption.Ed is? The answer is very, but I'm sure you'd like a measure of accuracy...
Providing a percentage of accuracy for speech recognition is a challenge as there are so many variables and confounding factors. For example, we could say Caption.Ed is 99% accurate. On many videos this would be the case, however, throw in some poor audio or strange pronunciations and will it dip to 98%? A stand-alone figure out of context is of limited value.
We have therefore decided to take Caption.Ed and run it against a number of videos across a number of subject matters and then calculate the accuracy. We've documented the whole thing clearly in the attached document below.
