Trending on Google is Apple’s explanation of how Siri works. We all know you can say “Hey Siri” to get your iPhone to respond. Apple’s explanation? No, it’s not magic. It’s a deep neural network that converts the acoustic pattern of your voice into a probability distribution over speech sounds. Then a temporal integration process will computer a confidence score that you did indeed say “Hey, Siri.” If your iPhone thinks that maybe you said “hey, Siri” but it’s not quite sure, it sort of listens harder. That is, it becomes more sensitive to whether you’re trying to say it a second time. All I can say right now is “whoa, dude.”

From Product Hunt, Google Calendar has a new look. The new look will be rolled out to users of Google Apps first.

MegaBots won the battle by using a giant chainsaw to cut off the opponent’s arm. Why do the Americans have to win everything? If you want to see the video, again check out our show notes on
