bluetooth calls contact instead of starting svoice

[SpyMaster356]

I recently got a bluetooth headphone but when I use the command button on my headphones it calls the person that's the most contacted it does not open svoice at all and it even calls when the siii is locked. I have the aluratek ABH01F bluetooth headphones and jellybean 4.1.1 I would like the command button to open svoice instead of directly calling the most contacted
