My iphone keeps showing the voice command blue screen?

So yesterday i bought one of those arm bands for iphone from sports authority and that same day i used it on the gym but as soon as i putted the iphone in it stated unblocking itself an repeadetly showing the voice commands, it does this a few times then it affects the music, it restarts the song that its playing, then it moves it fast fordward and finally keeps skippin songs back and forth until it stops and automatically stops playing songs altogether… Today i didn't use the arm band and the same thing happened… I don't know if its the arm band that caused this or its some weird signal that i get when i go to the gym because none of this happened before or anywhere else, it only seems to happen when i use the earphones because i played normally everything without them… Please help because i don't want to have to delete or reset the phone!

Do your earphones have a remote on them? If so it can be malfunctioning like the button is held in which triggers the voice commands. Try a different pair of earphones. And check your home button if is stuck in it causes the voice command to come up.
