Narrative:
First officer flying had IAS hold and clamp on FMA. I was busy with setting the next turn on radios. With head in chart heard altitude warning go off. Looked up to see 11300 ft and slow climb of 100-200 FPM. First officer corrected immediately. Approach never said anything to us about it. Feel that it might have been caused by the descent still in IAS and reducing the vertical speed by power, which can cause a climb, especially if you hit some bumps as we did.
