The boys at Google are really stepping up this fight to ward off anyone that smells like getting close to their ecosystem and mainly their search business by making it better and better and better. You can try out this new feature by going to google.com (if you are using www.google.com.ng or any other url like this and you don’t see the mic sign, click the link that says “Go to google.com”)
…Oh! and least I forget, I couldn’t get the mic sign in Mozilla Firefox, so I guess you have to get the best browser I have worked with in recent times: Google Chrome!
