Other features in the new mobile operating system, iOS 6, include improvements to Siri, the voice-activated virtual assistant in the latest iPhone. While Siri initially worked with a limited set of Internet services — allowing users to, say, search for restaurants through Yelp — it will now let them use voice commands to search for sports statistics, make restaurant reservations using OpenTable and look up showtimes for movies. In some ways, Apple is using Siri to sidestep Google by reducing the need to consult Google’s search engine.
