From what I have read on Articulate's community forums (and other sites) is that NVDA does "everything" that JAWS does. I support Lisa's request in asking Articulate to support the use of NVDA as a choice for developers and learners.
I think NVDA is used more than JAWS for a variety of reasons, one of which that hasn't been mentioned is that NVDA lets developers read what is being read by the screen reader - helping us (okay, me) with my limited speed listening capabilities.
I guess I am asking Articulate (and the staff that answer questions on the forum) to quit dismissing NVDA as an alternative - making it sound like NVDA isn't a quality product and JAWS is our only answer.
Nicole, thanks for working on this tough issue. I am surprised and pleased that you listed NVDA as an alternative!
Accessibility in our deliverables is a work in progress for most of us. We need Articulate to be there with us since Articulate is our authoring tool of choice.
