The Japanese language doesn't have distinguishing R/L sounds and most Vocaloid struggle with Rin or Len depending.

Also note... It doesn't separate F/PH or TH/SH/Si, at time and don't even think about V/B/P sounds, nor can it pronounce correctly ending sounds like "lly" without saying "ri" instead. And there are a whole host of a bunch of other sounds.

As I just wrote else where, Vocaloids in Japanese only have 1/5 the sounds of English vocaloids (which is one of the languages you can use for distinct L and R sounds, there are others), but only share 40% of the sounds with English. I don't know the stats matching to other languages, but the Japanese Vocaloids are really phonetically limited.

Phonetics are a bitch when it comes to Japanese, and unlike the native population of Japan Vocaloids don't have the pleasure of learning new sounds to add to their library.
