Sources: Nuance Communications, BlackBerry, and Plug Power.

Speech and handwriting recognition expert Nuance Communications (NUAN) traded 14% higher this week. Hydrogen fuel cell systems builder Plug Power (PLUG 1.11%) shares gained 16%. Troubled smartphone maker BlackBerry (BB 1.10%) soared 26% higher in just six days.

There was no shortage of fantastic technology stock gains this week, even if the S&P 500 and the tech-heavy Nasdaq only traded 1.3% higher.

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.
