Vocaloid 6

Vocaloid 6 is a singing vocal synthesizer application developed by Yamaha Corporation. The successor to Vocaloid 5 in the Vocaloid series, it is the first to incorporate machine learning, branded as Vocaloid:AI. After scheduled maintenance of the official Vocaloid website on October 13, 2022, Yamaha released Vocaloid 6 without prior announcement. It introduces the Vocaloid:AI engine, which had been in development since around Vocaloid 3 and was first publicly shown in a concert, reviving the voice of deceased singer Hibari Misora. Voices developed for it offer improved synthesis quality, multilingual singing and drastically smaller file sizes. Support for older voices from Vocaloid 3 and up remains. It also features the addition of Vocalo Changer, a tool that converts the voice from a singing recording into that of a Vocaloid voice. Other additions are support for ARA 2 and an updated UI. A trial was released on the same day. A pair of English voicebanks and a pair of Japanese voicebanks, one each masculine and feminine.
