The sites that Googs returns are basically the internet's version of googoo gaagaa. I look at the websites returned, and often think that the site's owners must be morons. Useless drivel clearly designed to game the Goog search results. I think think about how moronic it is that Googs allows this.
I suspect they know the sound they want to make but they don't know how to articulate it. They make an approximation and we can encourage them repeating the correct version, so they realize we understood what they're trying to do: "you're half way" but repeating their approximation is misleading.
I subscribe to the theory that this helps babies understand what they sound like, and therefore helps them learn how to produce the sounds they want.
Congratulations on recognizing the true morons.
