Various things, such as more softness (loose pronunciations), more sharpness on consonants/vowels, more loudness, etc.

Basically, its Miku's vocal adjusted in 6 different ways but in each case they have a new set of recordings. Possibly not 100% all the voicebanks, but generally across the voicebanks (CFM are known to cheat from time to time so never know 100% whats going on), so you can adjust any of these 6 and they won't in theory behave at all like the original and likewise the original won't behave like any of these.

The page covers the overall differences between vowels, but there are 3 soft and 3 solid voicebanks, each set of 3 has a high, medium and low range voicebank.
