Speech and handwriting recognition expert Nuance Communications (NASDAQ:NUAN) traded 14% higher this week. Hydrogen fuel cell systems builder Plug Power (NASDAQ:PLUG) shares gained 16%. Troubled smartphone maker BlackBerry (NYSE:BB) soared 26% higher in just six days.

In a field with dozens of interesting jumps, these are three of the most exciting tech gainers between June 16 and June 20. Nuance might be for sale, Plug Power is riding a wave of big news elsewhere in the fuel cell industry, and BlackBerry isn't dead quite yet, thank you very much.
