I don't think it's possible to use Dictation without sending ALL spoken data to Apple.
The process assistantd is launched.
I own both Little Snitch and HandsOff!. These images are all that little snitch offered with the popup after I went in and disabled its default and protected rule which is referenced in the block-quote below the image. Protocol 6 I believe is HTTPS, so http with SSL.
If the connection to guzzoni.apple.com is not completed in some fraction of a second (tested with 3 controls this), then the little dictation bubble / microphone icon just goes into the 'close' mode. I might try following activity with Fseventer later too, but I'm out of time at the moment. Also, I captured activity sent but it was just a bunch of garble, probably b/c it was already encrypted at that point.
Another workaround that I may try:
install a Mountain Lion virtual Machine, and use dictation there. I'll report back on my findings, especially if I have a good experience with emulation (VMWare is my preferred program).
+1 to the other workaround too!
From the default rule that I temporarily disabled to bring up the pop-up.
action: allow
direction: outgoing

help:
This rule is necessary if you want to use Apple’s dictation services.
