UTAU is a free singing synth. It shares a lot of similarities to VOCALOID and in some ways it is responsible for the creation of Synth V.

The major difference between UTAU and those other softwares is that anyone can make their own UTAU library!

How many people have done that? How many unique characters are there? The number may shock you!
