I'm not very good with Russian soft signs, which is precisely why I made this course with nostr:npub1rphz5sucpva3vr3y00k7tm3rwcg5p0pecz43tlk7z4jntfx9q28sm5q22w - she is the expert. Nonetheless, whenever I listen to брат and then брать, I hear a sound like a hi-hat or a cymbal at the end of the verb брать. But I can understand how that may sound closer to TY than TS for slavic native speakers.
