Since I thought Polish was Icelandic (of all things), I decided I should hone-up on my listening skills - an area I slack on in all of my languages. I brought along all my Polish books to my sister's and have worked out a plan for the dialogues:
~Listen 5x w/out looking at the transcript (to get a feel for what the speakers are saying).
~Listen and repeat 5x while this time looking at the words (to visually match sounds to letters).
~Listen and repeat 5x again w/out looking at the words.
I also like to do the reverse. Instead of waiting for the speaker, then mimicking them, I'll speak first and see if they match me.
