Voiceroid Wiki

AH-Software Co. Ltd. (株式会社AH-Software, originally Artist House Solutions Co. Ltd. or ArtistHouse Software[1]) or AHS Co., Ltd. (株式会社AHS) officially, is an importer of digital audio workstation and encoders in Tokyo, Japan. It is also known as the developer of the VOICEROID series.


AH-Software was established in 2005 as an importer and seller of music software in Tokyo, Japan. In November 2009, they announced that they were going to distribute VOCALOID2 and Voiceroid products in December 2009. AH-Software became the fifth developer of music voice synthesis software with this release.

After a successful campaign in Germany, they began to expand and announced their plans in Vienna Austria.[2]

On June 26th, 2020, they announced they would distribute Synthesizer V Studio products starting on July 30th, 2020.[3]

On July 22, 2020, VOCALOMAKETS announced that a CeVIO AI singing voicebank for Yuzuki Yukari –whose VOICEROID and VOCALOID voicebanks were distributed by AH-Software– would be developed; VOCALOMAKETS noted that their goal is to "further expand the range of singing voice synthesis".[4][5] Taking note of this, on October 30th, 2020, it was revealed that VOICEROID plans for Koharu Rikka –which was also to be distributed by AHS– had ceased in favor of having her talk software be on CeVIO AI Talk instead due to a desire from TOKYO6 ENTERTAINMENT to be on all the latest technology at the time of Rikka's eventual release;[6] those who were disappointed with the decision were given the option to apply for a refund if they had contributed to her crowdfunding campaign. This would mark AHS' first official incursion into CeVIO software; the later announcement on December 25, 2020 of CeVIO AI Tsurumaki Maki[7] would signal AHS' eventual phasing out of VOICEROID in favor of CeVIO AI Talk.
