My brain, its Melting

So, I'm looking for some voice synthesis chips for a project at work today, trying to find out which ones are worth getting in some samples/development boards of. They all have nifty little programs which will translate any text you enter into a .wav file, which is suppose to sound like the actual chip will. I found a demo of a company called Winbond Electronics Corp.'s chip which is designed to record sound. Here's the sound file they used (right click, and choose save Target As). Its all sort of normal, although weird until you get to the little jingle they have at the end. There's no way to describe it...you must listen to it. Then quickly listen to some other song to get it out of your head, otherwise your brain will explode.
