I have checked the resources I have available and I am not showing this to be a recognizable feature. If you check out https://www.onstar.com/web/bluetooth/phones/phone?brand=Chevrolet&mod=2012+Chevrolet+Equinox+With+MyLink&provid=Verizon&phone=device-verizon-apple-iphone-4s the link that is Titled “Phone voice-recognition activation” is grayed out.
I hope this was helpful.
