Looks like a very interesting tool, but I would reallllly recommend hiring someone else to narrate your videos. That woman has a very "unique" voice that made it hard for me to sit through.
That's a bit harsh. In case it wasn't clear from my posts or the website I am not a native English speaker nor is my friend or the woman in question. She is my sister and just wanted to help when we were starting. I didn't hire anyone to do anything in the website :)
Do you have bounce rate stats on the video? Those will tell you whether or not you should re-record narration with a professional. (And as far as costs go, that's not very expensive.)
I didn't mean to offend you, and it really shouldn't. I think very few people have voices that translate well to "radio". That's why voice-over artists have jobs ;)
