It's not a real human voice. It's AI. you put lyrics into the AI and the topic or genre and click on generate. As far as I know many people use "Suno" for that.
I write the lyrics on my phone and then import it into a software that’ll create a song from said lyrics. I also use a separate editing software to fine tune it because even though it does a good job, it’s still AI and makes mistakes. I’ll be adding my own vocals to my music soon.
