The voice-AI project Soyogi Fractal, produced by voice actor Yuki Kaji, officially released the English Talk Voice for the voice synthesis software “Soyogi Soyo” (CeVIO AI / VoiSona) on Wednesday, December 10, 2025.

With this release, Soyogi Soyo now supports English in addition to Japanese, enabling creators in Japan and overseas to generate spoken lines and narration in a broader range of expressive styles.

The product was originally announced during the crowdfunding campaign “[Yuki Kaji AI Voice Project | Soyogi Fractal] ‘Soyogi EXPO’ Begins!” held from July to August this year, and early access distribution was provided to eligible backers in November.
