Using Melodyne for tuning?

[krutoi2000]

Can I use Melodyne to extract pitch of voice and place it in Utau?

What you want is a pitch analyzer. We aren't able to use melodyne, but we already have crepe, an open source machine learning pitch analyzer for frq generation of voicebank audio file. We can make it support analyzing pitch from audio part to voice part.
