Human Factors
We pushed off of Gate XY on Ramp Z with clearance. We called for taxi and were cleared to taxi on the right. After crossing the center roadway; another carrier that had pushed off the gate onto the left lane powered up and transitioned into the right lane right in front of us. To avoid contact; it required more than normal braking. I could see the F/O on the (other carrier) aircraft; so I assume he could have seen us if they had cleared their turn. I questioned the Ramp Controller but I think she was confused by similar call signs.  We were taxiing at a slow appropriate speed.
Air Carrier Captain reported a critical ground conflict with another air carrier that cut in front of this Captain. Evasive braking was required. Similar call signs may have contributed.
