15.ai vs. Murf: A Voiceover Showdown

As impressive as 15.ai’s ability to generate voices of various fictional characters from different media sources is, it lacks depth in several areas, which Murf, in turn, is more than happy to provide. This includes voice customizations, the ability to add media and soundtracks and sync them with the voiceover, and much more.

What is 15.ai?

15.ai software is a non-commercial freeware AI web-based application that can be used to create natural high-fidelity emotive text to speech voices. Launched in March 2020, 15.ai developed by an MIT researcher under the pseudonym “15.” The platform allowed anyone to use its AI-generated voices for free, as long as the usage was non-commercial, and 15.ai was credited. It became a popular tool for content creators and podcasters, offering lifelike voice cloning without requiring users to sign up for an account. 

On January 14, 2022,  Voiceverse NFT, a company associated with voice actor Troy Baker, was caught plagiarizing voice lines generated by 15.ai for their marketing campaign. They manipulated AI-generated voices of characters from My Little Pony and falsely claimed them as their own. After 15.ai’s developer exposed this with log files, Voiceverse admitted the plagiarism, blaming their marketing team. The controversy, which coincided with Baker's partnership announcement, led to public backlash due to both the plagiarism and environmental concerns around NFTs. Baker eventually ended his partnership with Voiceverse following the scandal.

In the aftermath of this controversy, 15.ai  went offline on September 8, 2022, and despite multiple updates from its Twitter account, it has yet to return as of October 2024. Users are still waiting for its re-launch, although it is unclear if and when the platform will come back.
