Have you used AI speech generation apps for your content?

Hey folks! Have you used AI speech generation apps for marketing videos, podcasts and so? I've tried several platforms but the quality was bad, it was very obvious that the speech is generated. That's how I decided to create an app with very nicely done speech generation. To make it more fun I took All-in podcasts Besties as main voices for the app. Btw, we are LIVE on PH today.
