Who is this girl with red hair?

SF-A2 opens Miki, a virtual female singer software developed and sold based on Yamaha's VOCALOID 2 speech synthesis engine. It is produced and sold by AHS(AH-Software) Company, which once developed a famous software "CrazyTalk", which can make pictures speak. It is the first bomb in the singer series, using the original super-runner Furukawa. It can truly reproduce the singer's voice, and it can also become the voice of other characters after adopting high-pitched or low-pitched mode, making Vocaloid more plastic. You can use Vocaloid to create songs with harmony.
