Introduction to NANSY Model

NANSY(Neural Analysis and Synthesis) model-based voice AI technology from Supertone generates high-quality voices that are difficult to distinguish from real human voices. NANSY is an integrated neural network framework designed to perform voice-related generation tasks. This model serves as the foundation for various downstream tasks such as voice and song synthesis, voice conversion, and voice design. Through its integrated structure, it maintains consistent voice characteristics during the generation process, and can express anyone’s voice through the control of four individual elements.
