Unlike some past Vocaloids, users can use her image on CDs, flyers and posters without requesting permission, although some consent from the company is needed for greater use of her image. The licensing for IA is slightly different than past Vocaloids. Her promotions have taken the approach to make her seem otherworldly and mysterious.

Information on IA was released much slower than the average Vocaloid. In Jan 2016, it was announced she would be released for CeVIO Creative Studio, receiving a talking vocal. Once imported into the Vocaloid 4, it was possible to cross-synthesis the two vocals.

On June 27, 2014, a new add-on for IA, called IA Rocks, was released. In 2014 a prototype vocal called 'IA -Aria On the Planetes- α Type C' was released as a free trial version via a one-month long feedback campaign. In October 2013, IA's software was announced to have an update for the Mac during the promotional period for the IA × Super GT Circuit Beats album. The design philosophy 1st Place worked toward was to make the voice simple and straightforward but easy to adjust and customize, letting creators create their own version of IA. She was the first release for the 'Aria on the Planetes' project, of which the CeVIO Creative Studio vocal also made by 1st Place, named 'One', is also a part of. Her voice was created by taking voice samples from Japanese singer Lia at a controlled pitch and tone. Because of this, production began on IA as a way to 'stand in' as a substitute during the singer's absence. She was illustrated by Aka Akasaka, the author of Kaguya-sama: Love Is War and Oshi no Ko.Īfter Lia got married and was expecting a baby she was forced to put her career as a singer on hold. IA's name was taken from her voice provider's name, 'Lia'. A rhythm game featuring her called IA/VT Colorful was made. She has performed at live concerts onstage as either an animated projection or a Pepper's ghost. Her voice is created using samples of Lia. They use Yamaha Corporation's Vocaloid 3 singing synthesizer technology. IA ( Japanese: イア) is a humanoid persona voiced by a singing synthesizer application developed by 1st Place Co., Ltd., headquartered in Meguro, Tokyo, Japan.
