Looking for song name & artist. No instruments. Female singer(s). Uses auto tune robotic voice (Cher effect)?

Question

I heard the end of this song on the radio the other day, but didn't catch the lyrics and then afterwards they didn't name the song. It's a very dramatic song, with moments of silence. I don't recall any instruments, but the robotic vocal effect (like that named after Cher's Believe song) was heavily used. Just female voice(s). Might anyone have a guess what song this might be? Thanks.
