I've noticed in my 1a version f2 that its very quiet. I think you should take a tip from Rosetta stone and have more speaking during writing and matching exercises. The more times you hear a word pronounced correctly, the easier it is to do it yourself. Also there's nothing which detects your pronunciation skills. I think this is a big flaw! It may not be perfect in other programs but at least they try! Unfortunately it took me a while to really try to use this program, otherwise I think I would have returned it. This is better for grammar, but grammar is easily learned from a book.
Also, side note, when looking for updates it asks if it says version 2.5 on my CD. Mine says f2, so how can it possibly be the "most up-to-date version"? That's just illogical. I was hoping for some update to add more spoken Spanish!
