Human Factors; Procedure
During taxi out; in very low visibility; DEN Ground control issued taxi clearance to us all the way to [Runway] 34L on [ Taxiway] WA; while another Controller on another frequency issued taxi clearance to [another air carrier] aircraft to exit the WA de-ice pad to our left and in front of us that caused a near miss on Taxiway WA. Due to the very low visibility (400 RVR) we saw [other aircraft's] position lights at the very last second and immediately brought our plane to a stop on WA just prior to colliding with [them]. We then immediately asked ATC for an explanation. The response was an apology and that both aircraft were issued taxi clearance on separate frequencies and in error.
Air carrier Captain reported an abrupt stop was required to avoid a collision during low visibility taxi at DEN involving another air carrier on a different Ground Control frequency.
