Glossary

15.ai was a freeware artificial intelligence web application that generated text-to-speech voices from fictional characters from various media sources.[5][6][7][8] Created by a pseudonymous developer under the alias 15,[1][2][3][4][9] the project used a combination of audio synthesis algorithms, speech synthesis deep neural networks, and sentiment analysis models to generate emotive character voices faster than real-time.[a][10][11]

In early 2020, 15.ai appeared online as a proof of concept of the democratization of voice acting and dubbing.[9][12] Its gratis nature, ease of use without user accounts, and improvements over existing text-to-speech implementations made it popular.[6][5][7] Some critics and voice actors questioned the legality and ethicality of making such technology so readily accessible.[13]

The site was credited as the impetus behind the popularization of AI voice cloning (also known as audio deepfakes) in content creation.[2][9] It was embraced by Internet fandoms such as My Little Pony, Team Fortress 2, and SpongeBob SquarePants.[1][14][9]

Several commercial alternatives appeared in the following years.[2][3][4] In September 2022, a year after its last stable release, 15.ai was taken offline.[3][2] As of November 2024, the website was still offline, with the creator's most recent post being dated February 2023.[15]
