Enjoy but would like... – Learn Persian - Free WordPower Review

I really enjoy this app so far. I'm learning words pretty quickly. However some words are difficult to understand what the speaker is saying. Like "kheyr". I still have no idea how he's saying it. It would be cool if on difficult words that the speaker spoke slower OR if there was an option to hear the sentence or word pronounced slower and possibly a English visual of the word being broken down to sound it out but not necessary.
