Template:Oliver V3 voicebank

Oliver is a young male Vocal with a choir-type singing essence, though capable of singing other genres. He sings with a british accent. Unlike Kagamine Len and Ryuto, which are also "young boy" voice types, he was voiced by a provider that actually was the same gender and intended age, thus is a more accurate match for that of a young male vocal. He also has several additional sniplets that can be imported into the Vocaloid 3 editor. He uses both the V3 import method and V2 BR1-BR5 method for his breath samples.

Early reports on Oliver upon his release were positive and he is one of the better English Vocaloids produced, having notable improvements over past English Vocaloids and being relatively easier to get results then many others. His vocals have similar traits to Sonika, without being as muffled. He is clear on most notes and can hold long drawn out notes well, but has some trouble with shorter notes. He has improvements over past Vocaloid 2 vocals and in his raw (before tuning) state is much smoother overall. He is capable of sounding emotional more easily then past English Vocaloids and has improved language skills. Some non-native English speakers say it is slightly easier to use his phonetics to speak other languages with than past English capable Vocaloids.

Although it is common for Vocaloids to have issues on higher notes, Oliver has a particular heavy softness on higher notes that can limit the genres he can be used for outside of choir.
