Aqua Voice is an amazingly useful and reliable speech recognition system. I acquired a disability as an adult and used Dragon to adapt as an accessibility aid for decades. When Aqua hit the scene, it didn't take me very long to change to just using Aqua, and it's been months since I even started Dragon.
To understand how wonderful Aqua Voice is, you need to have used Dragon. At first, Dragon was wonderful; it turned speech into text, but you had to watch it closely and edit what it recognized every sentence or two. If you're disabled, it's a lifesaver, but it's still highly annoying. In contrast, Aqua is sufficiently accurate; you don't need to edit the recognition results. And because Aqua is so accurate, using speech recognition when writing is much more relaxing.
In order to get the sixth-star rating, I really need a Linux client that's on par with the Windows and Mac clients.
