Narrative:

Air carrier flight took off from cle airport on runway 23L after being cleared for takeoff on runway 23R. This incident happened because of poor crew coordination and miscom. Taxiing out for takeoff, single engine to conserve fuel, flight was cleared to taxi to runway 23L. After starting the second engine late, I called for the takeoff checklist. While we were completing the takeoff checklist, the ground controller switched flight over to cle tower. As soon as we switched to cle tower, in the middle of our takeoff checklist, flight was cleared for takeoff. As it turned out, cle tower had cleared us to cross runway 23L and cleared another aircraft to takeoff on runway 23R. I didn't hear cleared to cross 23L and takeoff on runway 23R but I thought I heard 'cleared to takeoff on runway 23L.' no conflict. I rushed the first officer where he was no longer in the loop but only working hard to complete the takeoff checklist. My crew management broke down by not giving the first officer and myself the necessary time to do our jobs. The takeoff situation in cle on runway 23L and 23R is most demanding and requires full attention by all crew members.
