VoiSona's 2026 release slate includes three newly shipped or announced voice libraries: Ui for VoiSona Talk, Nanahi for singing, and Bennett Fantasia as a bilingual singing voice. Ui's subscription, package, and download sales have opened, while Nanahi is dated for December 12 and Bennett Fantasia arrived on September 27.
VoiSona's 2026 lineup has broadened from singing voices into talk synthesis, and from Japanese into bilingual libraries. Ui, a Japanese talk voice library voiced by illustrator and VTuber Shigure Ui, was announced in May for a summer release through VoiSona Talk. Sales for VoiSona Talk Ui opened on September 14 in package, download, and subscription formats, with five emotion styles: Normal, Happy, Angry, Sad, and Sweet. The package edition's limited-quantity special edition has had its sale date postponed and is undecided.
The singing side moved in parallel. Techno-Speech announced in September that Nanahi, voiced by singer Nanahira, would be released on December 12 with three switchable voice styles: Upper, Sweet, and Calm. Pre-orders for the fully made-to-order package edition ran from August 31 through October 31 at 14,800 yen, and a sample video of Nanahi covering Kinoshita's "Erai Erai Erai!" was posted to the VoiSona YouTube channel.
In October, Techno-Speech released the Bennett Fantasia library on September 27. The character is produced by the Australian company VoCreatures Pty, Ltd., with Du Du Danyon as CV and Staircatte on illustration, and it sings in Australian English and Japanese across Natural, Boisterous, and Operatic styles. Download plans run from 880 yen per month to 13,200 yen perpetual, and a limited package version ships in late 2026 at 180 Australian dollars.
Across the four announcements, the platform's 2026 additions span talk and singing roles, Japanese and Australian English, and a range of purchase models. Ui's special edition remains the only item whose release has been pushed and undated.
