AH-Software Co. Ltd. (株式会社AH-Software, originally ArtistHouse Software Co. Ltd.[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.

History[edit | edit source]

AH-Software was established in 2005 as an importer and seller of music software in Tokyo, Japan. Planning of the first three AH-Software Co. Ltd. vocals began in 2007. 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 the retirement of the VOCALOID STORE, they also began to sell physical copies of Macne Nana.

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

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

VOICEROID[edit | edit source]

VOICEROID is a speech synthesizer program developed by AH-Software, released on December 4, 2009. It's name is derived from "VOCALOID"; however VOCALOID is meant for singing, while VOICEROID is meant for speaking.

The VOICEROID software has several uses including music, education, and for those with disabilities which may impede speech. Later versions are capable of several emotions, and the software is overall considered very simple to use.

Usage[edit | edit source]

The user is able to adjust the speed, pitch, and intonation to make the speech generated by the program sound more natural. VOICEROID enables the user to type in any word or phrase and the selected character will repeat it back to them.[4] All original VOICEROID and VOICEROID+ products were packaged with the animating software, Crazy Talk SE.[5]

There have been two versions of the software so far, VOICEROID and VOICEROID2.

It uses AITalk though is not compatible with any other Talk software used by other VOCALOIDs. Because it uses a different engine from VOCALOID-flex, it does not use the same licensing as VOCALOID, and is restricted to just AH-Software as a voicebank development source.
