Tsukuyomi Ai (月読アイ) is a VOICEROID and was one of the first VOICEROID voices in the series to be released, along with being the first female. She and her "brother" product, Tsukuyomi Shouta, were released on December 4, 2009. Her software was later upgraded to VOICEROID+ EX in 2015.

As a product she is either sold as a single package or with her "brother".

Vocal description

Tsukuyomi Ai is based off a "five year old female". In comparison to her brother, Ai is a slightly higher pitch. Her voicebank is also very soft sounding, leading to a few issues on pronunciations, but sounds fairly natural. She, like her brother, also has the voice of a pre-teen child so therefore has some flexibility to the vocal for gender-based roles. She is not aimed at a mature audience and contains censorship of certain words.

Voice samples


  • Her profile states:
    • She has a father, mother, and a brother.
  • Released around the same time as Ai and also Tsukuyomi Shouta, two of Ah-Software's VOCALOIDs, Hiyama Kiyoteru and Kaai Yuki, were at fear of being subjected to pedophilic or "Lolicon" works. Because of this, both Shouta and Ai are critiqued by some as "Lolicon."
