It's hard to see, at first, what a product like Narrator can do for you. But once you play around a bit, the uses become clear. Narrator is kind of like Shrek, who equates an ogre like an onion - there's lots of layers.
So, for one layer, if you're like me, when you write a letter for a business purpose, you need to read it out loud. A lot. Yes, you can read it yourself, but in order to be effective - you really need another voice. Narrator cleanly fills that role. As a small business owner, Narrator sure has come in handy.
Another layer of Narrator that again, isn't as apparent - is as a study buddy. Now, I am a visual learner, so I really appreciate things like diagrams and videos. I need to see what I am learning. So knowing that a product like Narrator can act as a study buddy for those who need to listen in order to really learn their material - well, let's just say that I can sympathize and wish that there was something like that for us visual learners when we were in school.
Lastly, as someone who is going to have to be on the lookout for AMD (for the uninformed, that's Age-related Macular Degeneration)and who already has a family member with it - in addition to books on tape and the like, a person with low-vision now has Narrator which is one more way to enhance their quality of life. And that's no small thing.
I haven't gone through all the layers of this product, but if what I've uncovered so far is any indication of all that's inside Narrator, I know that I will not be disappointed.
