Whats the point in the text to speech on it? It doesnt even work. You get about 3 words in and it stops, and puts the wrong words into the page. There's no support for 'full stop' or anything like that.
Seems very gimmicky.
IMO free WYSIWYG wise, CKEditor 4 is (sadly) the best option. However Redactor is very nice, but not free to use.
