Voice NFT start-up Voiceverse appropriated third-party voice lines without permission, prompting a backlash against the company.

Voiceverse NFT used voice lines generated by 15.ai without permission or proper attribution, manipulating AI-generated voices of characters from My Little Pony, pitching them up to make them sound different and falsely claiming them as its own. 

The 15.ai creator discovered the ruse through log files and publicly exposed Voiceverse's actions. 

Voiceverse later apologised and pinned the blame on its marketing team. 

The company describes itself on its website as having been 'built with unique, next-generation AI to provide everyone a "Voice for the Metaverse"'. 

The fracas occurred in the context of a broader push to monetise AI-generated voices through NFTs, despite ethical concerns and potential negative impacts on the voice acting industry.
