Cartesia voice clone review: 10-second sample stays stable on long audio

The author tested AI voice tools for long-form audio and cloned his own voice to read a full tutorial script. Most tools sounded good for the first few seconds but drifted in tone over time; Cartesia held up. It needs only 10 seconds of voice to create a clone, accepts up to 60 seconds to preserve accent, and he jokes the clone sounds "more real than I do."
