Yes, those sounds that twist our tongues even when we no longer have major issues with grammar and manage to make ourselves understood. Most foreigners never get pronunciation right and they can be spotted immediatly, but that's part of the fun when it comes to learning Polish (or any other language, for that matter, but it may be that I am highly subjective, I love all my accents). So here's our attempt at making these very unfriendly sounds a bit more friendlier: Polish Consonants.
Anna, we do hope this helps :) Enjoy!
