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.
