The verdict

KDP Virtual Voice is free and frictionless if you're already in Amazon's ecosystem. But you can't download the files, you're locked to Amazon, and the 40% royalty is lower than what you'd earn distributing independently. StoryVox costs money upfront but gives you files you own, distribute anywhere, and earn higher royalties on.

Frequently asked questions
