Since then, three Tetos have existed: "UTAU Teto," a free singing synthesis software developed by Ameya/Ayame; "SV Teto," a high-performance singing synthesis software developed by Dreamtonics 15 years later; and "VP Teto," an AI-powered text-to-speech software developed by Dreamtonics 2 years after that.
