Have you ever wanted to make Unity-Chan say anything you can think of without the hassle of the Unity Engine? How about making her speak high pitch or sound like a man? User @kaigyoPG has done just that. This is a stand alone program, therefore you do not need the Unity Engine to use it.

“I made an Application Demo for Unity Voice Changer Filter. You can download it from the URL. Unity Chan will lipsync to match the voice changer”
Just plug in a microphone, say anything you wish, and she will repeat your every word, laugh or even repeat the clicking sound of your keyboard. There is also a short sample voice where she uses the “welcome to the aperture science computer aided enrichment center” quote from Portal. If you have had enough of her default voice, then just use either of the sliders to change the pitch or formant of her voice. If you do not feel like playing around with those, there are two preset settings as well.
You can also change her facial expressions by selecting one of the many options on the left column under “Face Update”, as well as change her pose by cycling through “Change Motion” on the top right corner or just use the space bar. Currently this is only a demo, but hopefully there will be a full version later on.
