History[]

2022[]

On September 1, 2022, Techno-Speech, Inc. announced a new upcoming VoiSona vocal based on the voice of Sumire Yoshida (吉田菫) (known professionally as Suu (すぅ)) from the Japanese band SILENT SIREN (サイレントサイレン).[1]. The name "AiSuu" was officially filed for trademark by Techno-Speech, Inc. on September 28, though, at the time, unbeknownst to be the character's name.[2] Two silhouettes featuring the two new upcoming VoiSona vocalists were released on November 24 with information to be revealed in the following week.[3] AiSuu was officially revealed on December 2 to be the final name of the product and she was scheduled to release simultaneously with Kirune, a male VoiSona library, on December 19.[4] AiSuu was planned to be released as one of Techno-Speech, Inc.'s first subscription-based vocalists priced at an annual plan of ¥6600 yen for one-year license, (¥6000 yen excluding tax) or ¥880 yen as a monthly license (¥800 yen excluding tax). Her first official demo, a cover of SILENT SIREN's original song Hachigatsu no Yoru, was released on the same day.[5]

On December 13, the official VoiSona Twitter account announced that Sumire Yoshida and Sho Kiryuin were invited to a special post-release DTM Station Plus! {DTMステーションPlus!) broadcast to be held on December 20, where information would be presented regarding VoiSona, AiSuu, and Kirune.[6][7] In addition, three official demonstration songs were announced to be in production for the two vocals respectively and would be released throughout the week up to the official release date on December 19.[8] AiSuu was announced to be receiving one solo demonstration song, CUGE!!! by Sohbana, and one duet song, 子供部屋のエチュード (Kodomobeya no Echuudo) featuring both vocalists by OSTER Project.[9][10]

Free trial editions of AiSuu and Kirune were announced to be released during the "Kirune & AiSuu Release Commemorative "Free Trial Campaign"" (機流音&AiSuuリリース記念「無料お試しキャンペーン」). Registered applicants who applied through the official VoiSona website between December 19 at noon through December 22 (23:59 JST) would be eligible to use both voice libraries for free for one month after the application. To be eligible for the trial edition, applicants must access the "Apply for Annual Plan" or "Apply for Monthly Plan" buttons at the bottom of each respective vocalists' product page and register their credit card information. Applicants could purchase a subscription plan for 0 yen for 1 month. By default, it was noted that after the one-month free period ends, users would be automatically transferred to the first selected subscription plan (either yearly or monthly). If users did not wish to continue the paid subscription after the free period ends, users were directed to access the campaign page during the free period and press the "Cancel Reservation" button. After the free period ends, the automatic renewal process would be turned off.[11]

AiSuu was released on December 19 as intended.
