Lem (澪夢レム)

UTAU & Diffsinger Voicebank & Furry Character

Lem is a shapeshifter character;
a voice for various voice synthesis softwares.

Lem the Shapeshifter, also known as Lem.ma or 澪夢レム, is a free virtual singer and AI vocal synthesizer similar to Vocaloid or Synthesizer V. Powered by the open-source engines OpenUTAU and Diffsinger, Lem UTAU voicebanks provide multipitch vocal libraries with an exhausitve phonetic set and rigorous diphone coverage, ensuring seamless, high-fidelity synthesis across multiple languages. For modern AI workflows, a free Diffsinger model is also available, bringing that same linguistic depth to neural rendering.

Beyond the voice, Lem is a character designed for adaptation. His visual identity serves as a creative framework for creation of derivative lem-shapes. Whether utilizing his Civet, Quoll, or Phascogale forms, or deriving entirely new iterations, Lem invites you to reshape his design to fit your unique artistic vision.
