“MECHASUZUKA” is a next-generation singing voice synthesis library that uses AI technologies such as deep learning to faithfully reproduce the voice quality, nuances, and singing style of Ichimatsu Suzuka, a Japanese Ichimatsu doll–themed VTuber. It includes three distinct voice tones: “Soft,” featuring a gentle, whisper-like tone; “Powerful,” delivering strong and expressive vocals; and “Su,” a standard singing voice. Each voice supports both English and Japanese.
