I've just started to use the addon. The Google TTS API sounds much better than the HTML5 one of course. But I am immediately struck by the fact that it speaks slower than I can read. So it's great for when I'm tired of reading, but it would be a fine addition to be able to increase or decrease the speed of the voice, depending on the technical difficulty of the text.
