"Hey, Siri": Apple allows you to activate the assistant by voice only, builds in Shazam song recognition
Apple has also added music recognition capability directly into Siri via a partnership with Shazam. The feature was rumored before the event, and it has turned out to be indeed true.
Siri also gets a few new features: you can now make iTunes purchases via voice, plus Siri now takes commands in 22 additional languages.
Finally, Siri is integrated with Apple’s new smarthome iOS features. You can just say to Siri "get ready for bed" and you’ll have your smart home lock doors and dim the lights. Neat, isn't it?
