Narrative:

Ground gave me the following clearance to taxi; 'expedite taxi; jet traffic on charlie. Taxi charlie and alpha. Cross runway xx.' I repeated the instructions and taxied onto charlie in front of the distant jet taxiing about a quarter mile behind me. I crossed the runway xx hold line. Ground had been quiet since my reply. Suddenly the words stop; stop were heard. I stopped the plane before reaching the edge of runway xx. I looked to the right and saw a cessna 182 at the other end (east end) on short final for runway xx. The cessna completed his landing and exited the runway about half way down the 5;000 ft runway.there was no other transmission on ground frequency after the word stop for a few minutes. Then the cessna was given taxi instructions. Then the ground controller instructed me to cross runway xx; right on alpha; which I did. No mention was made by the controller about stopping so I do not know if the controller said stop or the pilot of another airplane (the jet?) on the frequency said stop. However; I did verify with my passenger in the right seat; an avionics technician who was there to document performance of some new avionics; that I was cleared to cross runway xx. In my judgment; had I continued to cross runway xx and not stopped I would have been well clear of the runway before the cessna touched down at the other end. Furthermore; the voice that said stop; stop did not sound like the ground controllers voice.
