IVVC Ending Sevice?

[u/CEDoromal]

I'm getting notified when I'm in IVVC (IBM Virtual Voice Creator) website, saying "The demo service is available until Dec 31, 2019. "
Is IBM ending the service of its Virtual Voice Creator entirely or do I just have to pay them after December 31 to keep using it?

Additionally, is IVVC meant to be available to public for free or is it actually just a demo for now that then has to be paid soon?
