Getting the 'soft sign' (ь) right when recording myself

I spend 20 minutes every evening recording myself reading aloud in Ukrainian because I’m obsessed with getting the pronunciation correct. However, I’m really struggling with the soft consonants—especially when the soft sign (ь) appears before mid-vowels. I know I’m still sounding 'hard' when I speak. Has anyone used a specific recording workflow or app to isolate and master these specific phonetic shifts?
