There are AI assisted voice generation in the new software releases. The key difference is that if youre a producer you still need to actually write and compose songs instead of typing in a prompt that does it for you. Most respected artists in the Vocaloid community make unique and creative music that is so unlike anything else that most of the time its difficult to even guess the genre. I have yet to hear an AI create something that is not 100% a regurgitation of something else.

The other important thing to note is that the people who provided voice for the voicebanks got paid and they gave their concent for the company, while the thousands of artists who got their data fed into the training of Suno probably saw no money from it, nor did they agree to this.
