It's overrated and greedy! It's really not a good idea trying to sell my own computers hi-quality voices (from IVONA) to me again! Hey dudes, those voice files are my property, not yours! Why don't you simply let me use my already-bought voice files? Plus, it does not support real-time on-page Highlighting (of the sentence being read)! Try (Pericles) for chrome, it's outstanding and free (with enough features). I guarantee you'll like it.
