Very close to what I'm looking for, but app pauses to load for every sentence. If it ran smoother and didn't have to pause and load for every sentence, I'd be inclined to purchase this. I like the Ivona voices and the fact that is works with Google docs. It all seems like a great idea. Unfortunately, it is unusable if it has to continuously load.
