Here's something that might just blow your mind. If you perform a voice search and Google misunderstands you, or you happen to garble your words, there's a quick way to take care of that. Just follow up with a second search that begins with "No, I said..." Google will then replace the incorrect word with what you said the second time.
Here's an example. Let's say you're in a hurry to get to our lovely website, and you say "OK Google, take me to Android Police." It doesn't hear you properly, and somehow you end up with Android mobile.
