Talk:Kagamine Rin & Len V4 English/@comment-53539-20161102110325

just leaving a note here... Its been confirmed with Ruby that Vocaloid can add nasalliness to the vocal.

In fact, it turns out the issue is present to some degree in all Vocaloids and even the original Japanese Rin and Len vocals have it. Maybe its lesser to a degree or you've not noticed it. But once you compare to a vocal like Tone Rion which purposely does it, you can start hearing a little between purpose adding it to the RAWs and Vocaloid adding it better.

Gackpoid is likely another example of clean samples having nasaliness added. :-/
