Paul's Español Voice Demo
Record English. Hear Spanish in my cloned voice
Why I Built This
I built this prototype to understand Cartesia by actually building with it. My wife's family is Colombian, so the personal use case is to send warmer personalized voice notes in their native language because my spanish no es muy bueno.😅
