I designed the website of the project that distribute Voices as System sounds.
This project is planned by Azana, who planned “Wakusei Nostalgie (Nostalgie of Plannets)” and “Ayakashi-Uta” in the past.
Do you know that you can change the sounds of System Error or Skype ringing (etc.)?
You can download the system sounds by nice “voices”.
One of characters is a lovely girl, and other one of it is an humanlike android…
