SpeakUp has a world of applications. It’s up to your imagination to come up with the coolest ideas. Here’s a hint or two:

Use SpeakUp on top of the Pi click Shield to command XBMC
Home Media Center on Raspberry Pi®. It’s a great a replacement
for a mouse and a keyboard.

Replace your lamp switch with a SpeakUp click and a relay.
Tell your light to turn ON or OFF if your hands are busy doing
something important.
