A "Persona" is a complete AI character you design, defined by its unique personality, background, writing style, and assigned voice. Once created, it can generate written content in Threads and speak using its assigned voice in the Voice Over module.
You need approximately three minutes of high-quality, clean audio; for best results, we recommend a 44.1kHz WAV file. Crucially, you must have the legal consent of the voice owner, as Euryka is not responsible for how the cloned voice is used.
When creating a character, you can upload your own voice. This voice then becomes the character's default for all Voice Over generations and can be changed at any time.
We support over 30 widely spoken languages and regional variations, allowing you to create content for a global audience.
