DeepVocal
free vocal synth
Also known as Sharpkey
Not exhaustive; find more here
A program developed by Boxstar, once known as Sharpkey. Sharpkey development was restricted, but since the release of DeepVocal, anyone can make their own voicebank. The voicebank creation process is very complicated and restrictive compared to UTAU, but the editor is much easier to use. As of a recent update, the process of building voicebanks has been refined (model files). There are no other changes to the program yet, but it should be noted that voicebanks made with the new toolbox aren’t compatible with the old editor. (source)
