About the Report

In order to closely follow trends with captioning accuracy, and because ASR is such a critical part of our process, we are constantly testing to make sure we are using the best ASR engine. The results in this report come from research in which we investigate the current state of ASR technology with specific regard to captioning accuracy, in a year where this is particularly critical with a huge increase in online work and online education brought about by COVID-19.
