I think its likely a combination of voice provider and the sample tuning done in the voicebank assembly. It was stated in VY2's development, no filters were used on the VY2 voice, this allowed a natural flow within the voicebank since natural human-made vocal faults were kept in the voice. In contrast, CFM does process their vocaloid vocals.

Vocaloids are often tuned during development process because the engine warps the samples slightly.
