Is it possible to make some samples of the voices. When using the free version you only have the voice of Betsy, but when you pay, there will be other voices. I don't know if I like them too, so I don't know if I want to pay for it. Maybe it's possible to make some samples to introduce the voices in the free version? Maybe just telling them which sessions they are giving or something. Like: 'Hello I'm Tulsy and I will guide you to the sessions of Basic 1, 2, 3...'
