Talk:Yumemi Nemu (VOCALOID4)/@comment-68.117.163.74-20170630164458/@comment-53539-20170630182155

In a nutshell, for the most part they sound alike. The Vocaloids rely on layers of pitching... And how the samples are in the layers impacts how realistic the vocal is. Note that just 40% of the voicebank can determine how the major part of the vocal sounds, while the remaining 60% is just sound details, like making a vowel sound more bold if combined into a triphone or whatnot. These layers are broken down into Stationary and articulation, with both typical English and Japanese vocals having 2 of the latter.

Tone Rion's vocal is meant to retain a quality of tone of voice, so like Miku just sounds a particular way no matter what range you do. The most extreme example we have is Ryuto, whose Gachapoid vocal is the most notable example of voice acting the franchise has. Ryuto sounds like Ryuto no matter what range you choose. So her layers are... Well... Basically "here is a cute voice in high, low and med range".

The realistic vocals like Nemu's will change slightly as they go up and down the octaves. The reason is the pitches aren't identically recorded and have greater variation, allowing for the provider to sound as they would do if they were proper singing as normal instead of voice acted. Its quite common as a result for Vocaloids to end up sounding different in their higher octaves to lower, as the pitch layers aren't ness. identical in every way. Some vocaloids vocals sound more defined and bold high yet soft and weak low. Or even the opposite way around, either way they are often a lot more unpredictable, but most of all sound more like the providers overall. .

This aside, the vocal is no different to any other extra voicebank produced for Vocaloid, except the two different voicebanks have different characters heading them, while others have a single entity between them... Like in Megpoid, Miku, Fukase, etc case.

To be fair though, the difference between Rion and Nemu is likely due to recording processes. Traditionally, Vocaloids up to V3 were recorded in a wy that made using them easy, this was changed in V4 to recording the traits of a vocal rather then focusing on making the vocal easy to use. Rion is likely a product of the old way while Nemu the new, hence why she takes her providers name. If this is the case, you can hear for yourself the result of a simple change of recording style and its impact.
