Crab in iOS 8 will have, as has been repeatedly rumored, the option to allow us to quickly find out what songs we are listening to, all using Shazam. More than that, Siri can now recognize another 22 languages when dictating texts, can buy various content available through iTunes and has implemented a new voice command recognition system, all done via streaming from Apple's servers.
Apart from all this, the Apple company also implemented a function called Hey Siri that allows controlling Siri anytime and anyway just by saying this phrase, it being similar to the Ok Google of those from... Google.
