@Otter; I don't know enough ont eh chinese vocaloids to comment on them as individuals... But there are some assoicated things from the past you can take to mind.

It goes back to the point made in the V2 era, that the reason why many PVs have the lyrics in the video is because not always can any vocaloid be understood. It was one of the pointers brought up when someone said a English vocaloid was hard to understand, because for a long time everyone presumed the Japanese vocaloids has god-like clarity. This despite the Kagamines act1 and act2 having problems, few picked up Miku's "ma" problem, few knew that Miku was even mumbly on her vowels or choppy on most... Basically, a lot more went under the radar.

A human can "learn" to make themselves clear, a Vocaloid can't, and when you put two sounds together you can't be sure how they'll turn out.

At this point in time, its sort of going to go without saying that any language can encounter the same problems regardless of type, quality or language.
