Alvaro Cintas(@dr_cintas):I went looking for an AI voice tool that holds up on long audio. Ended up with a clone of my own voice reading a full tutorial script. Slight problem: it sounds more real than I do! Most tools I tried sounded great for the first few seconds, then the tone drifted the longer they talked. Cartesia held up. It needed 10 seconds of my voice for the clone, and it can take up to 60 to keep my accent closer. Recorded the whole process so you can try it too.
