Thanks for sharing! I'm a bit confused with the fluency score, what does it mean exactly? It would be good to have some feedback and pointers for improvement, otherwise I don't see myself using it for long.

Thanks for the feedback. The number of unique words you use and the rate at which you speak contribute to the fluency score. I'm a little reluctant to give the full equation, because it prevents us from trying to game it.

That's useful feedback on pointers for improvement - I'll see what can be done.
