There are other sites more suited for this task: reddit.com , reddit.com/r/programming , digg.com and others. As stated in http://ycombinator.com/newswelcome.html , "The worst thing to post or upvote is something that's intensely but shallowly interesting"
I think that this submission does not belong to the HN. It carries little educational value and I wouldn't call it deeply interesting (as described in ycombinator.com/newswelcome.html ). There isn't any effort to explain the beatbox effect. Also there are many voice synthesizers, google's is just the easiest accessible one. This is why the link seems to me just like a funny picture of a cat and I am deeply alarmed. (sorry for bad english, non-native here)
