I wondered this when she said "WYSIWYG". There are a few points where the tone of her voice suggests she is either at the start or the end of a sentence, but in fact she isn't.
I have a crazy idea about demo videos which you might want to A/B test against your current video: get your customers to record videos showing how they actually use VWO on their sites. At least I always find it a lot more convincing when I see a video in a normal voice showing me a real use-case rather than a scripted marketing video.
For example, the Basecamp landing page with real customer interviews and screenshots of the app looks a lot more appealing to me - http://basecamphq.com
Yeah, that's true. We clearly told her to speak it as "wee-zee-wig" (fearing otherwise she would simply speak each letter) but she stumbled on the word (I guess). I gather from comments here that we probably need to redo the audio.
Perhaps you could test out different voices, and test which ones people skip over vs which ones people watch all the way through? Doesn't youtube offer some stats on that?
