The reason why S Voice, Google Voice Search and all other Siri wannabes fall short is simple. They don't feel natural. Ask Siri who won last night's Yankees' game and she'll tell you the score. Then ask "How many hits did Jeter have?" and Apple's voice-controlled assistant will tell you, without having to specify that you're still talking about the same game. It's not a mere query, it's part of a conversation. Other new Siri talents include the ability to book reservations at your favorite restaurant via OpenTable and get movie times and reviews. The best in its class just keeps getting better.
