Default Voice control on camera app crash

Hello everyone!
I'm pretty newbie in Android world with a Galaxy S4 Mini Duos i9192. I got it rooted without any problem using a guide I found here in forum and I uninstalled every Samsung related app that it was useless for me. After this, I was searching here and there the phone and I found inside camera's app a setting about "Voice control" which was disabled. I tried to enable it, but the camera app exited without changing anything. So, every time I try to enable it, the camera crashed and exits. What is this option for? Is it related with S Voice or something similar to it?
Thank you a lot!
