The first cover song using Teto was created as early as April 6, 2008, and her signature song ' 耳のあるロボットの唄 (Mimi no Aru Robot no Uta)' was published on June 10 by Mimirobo-P. She was also released as an AI voice database for Synthesizer V Studio on April 27, 2023. Teto was announced to have a TALQu speech voicebank in July 2021, which later released on January 8, 2022. However, the voice could not be reproduced in a satisfactory manner.

came into contact with Mayo Oyamano, discussing the idea of turning Teto into a VOCALOID. In 2012, Tomohide Ogata from AH-Software Co. Teto was given official acceptance to piapro on April 1, 2010, and to Project DIVA on October 10, 2011.Īt one point, Teto was tested in the VOCALOID engine by Wataru Sasaki, but was scrapped due to not meeting expectations. The voice provider's name reading was then changed to Mayo Oyamano (小山乃舞世 Oyamano Mayo) to avoid unnecessary confusion. UTAU and Teto were both unnoticed among VOCALOID composers at first, but during the last half of the year of her release several creators started composing songs for Teto, causing her fame to be established during the following year. The Teto project continued after the troll campaign, and her vocal was recorded again for the use on UTAU, which vocal synthesis software was released two months earlier. Sen (線) provided the rough sketch and Nobuyo Oyama, a spoof for Doraemon's former voice actress Nobuyo Oyama, provided the vocal. Following the rising popularity of Hatsune Miku, 'Vippers' (Vip News users) schemed a troll 'new VOCALOID release' as an April Fool's joke.
