Adobe has added Speech to Text to the Public Beta, you no longer need to sign up to use it. Of course if you you are already signed up you can also use it in the release version.
Speech to Text is so good for doing testimonials I don’t know how i ever lived without it. It is fast and works so incredibly well. And having the script helps with comprehension so my edits just go faster. This is the most impressive feature in years, and it has quickly become essential to my workflow.
