This one never sounds fantastic to me, just "very good". It does have a very cool feature where you can input a phrase with one "feeling" to change the main text to have that "feeling" as well. It is a bit confusing to use.

I actually think Microsoft's TTS is the best and has many voices. IBM's Watson branded voice was a close second. But as near as I can tell, there's no way to run these locally, only through their cloud interface.

I'd say this portaspeech one was the best local I've heard but it annoyingly trips on words like "shouldn't".
