History[]

2020[]

A crowdfunding campaign was launched on May 28, 2020 to fund for Koharu Rikka's VOICEROID2 voicebank and its stretch goals, which included the final stretch goal for 25 million yen: a singing voicebank.[1] This amount was reached on June 6, about a week and a half after the campaign began, however the actual synthesizer was not specified at the time.[2] On June 26, Synthesizer V Studio was revealed as her singing engine.[3] On August 8, it was announced that recording for her Synthesizer V bank started.[4]

On October 30, Rikka was announced that she would be developed for the CeVIO AI voice synthesis engine for speech. For singing, she was confirmed to have both voice databases for Standard and upcoming Synthesizer V AI. She was slated for a Spring 2021 release.[5] [6]. In a press release from TOKYO6 ENTERTAINMENT, it was announced that Rikka would be releasing for CeVIO AI rather than as a VOICEROID product, with the reason being that CeVIO AI also uses AI technology.[7]

2021[]

On February 18, 2021, during an AH-Software Co. Ltd. Livestream, Rikka's Synthesizer V AI voice database was showcased.[8][9] Following the stream, AH-Software announced a special campaign on Twitter allowing users to apply via DM to receive a physical copy of Synthesizer V Studio Pro and Synthesizer V Koharu Rikka AI Complete.[10]

Rikka officially released on March 18 for both CeVIO AI and Synthesizer V Studio. Lite versions of the Synthesizer V voice databases were also released on the same day via AH-Software's website.[11][12]
