When you plug Siri in, in your car, for instance, you will be able to activate Siri simply by saying "Hey Siri". Additionally, the Siri can now identify songs using Shazam, which was originally rumored a couple of months ago. Siri will also support streaming voice recognition, letting you see what Siri is hearing as you speak, and enabling a faster response. The digital assisstant will also feature support for 22 languages with iOS 8.
