"how's your Polish learning going elilla&" I've learned to say "po polsku" and "makaron z truskawkami". I can't read the orthography yet and I don't know how to say "hello", "do you speak German" or "no", but I've learned that the retracted shibilants are spectrally less concentrated on the top frequencies than the laminals, which you can probably emphasise by rounding just the former class, also I'm pretty sure that voiceless shibilants assimilate a formant movement of the subsequent vowel already during the unvoiced part
