I typed in google translator "kind" and I didn't see the word "miły" in any of the translations. "Miły" itself is translated as "nice" or "cute" (again in google translator), like a Russian "милый"
Google Translate is not a good source of knowledge.
Although I'd personally say 'nice' as well.
I'm pretty sure the audio says "Znamy miłą aktorkę", could someone check?
