Heh, it's nice that a new background image is used, but it looks like a lot of the code for this widget is straight from Apple's "Voices" widget. If you install Apple's free developer tools, you can see the Voices code at:
/Developer/Examples/Dashboard Sample Code/Voices
Or try out the actual widget and you can play with the different system voices:
/Developer/Examples/Dashboard/Sample\ Widgets/Voices.wdgt
