^You know this is the second topic you responded... I will say generally Vocaloids are meant for the language they built for and for the most part, using them for other languages results in LQ results often and is difficult in general.

As I said, Chinese and English have more matching sound so unlike Japanese should be better, but there are rules that English voicebanks abide to that Chinese don't, since they abide to their own languages rules instead.
