Package details as noted:

Akari is meant to sound kind and gentle with the intention to portray a cute, bright female voice and under the theme of "starlight".

Her package also comes with an "exVoice" set. There is a voice release for VOICEROID2.

Vocal traits as noted:
  • She is able to sing a side range of genres from rock to pop.
  • While Yuzuki Yukari is meant to be an adult voice, Akari is a more cutesy vocal with a lighter tone.[2]
  • At 70bpm, Akari can handle slow songs relatively well, but not as well as Yukari at 60bpm. There are a few genres of music that Yukari can handle better than Akari.
  • Her tempo range is superior overall compared to Yukari and is double the size range. As a result, she can handle far more genres of music.
  • Aside from the slower song genres Yukari can handle, Akari covers all of Yukari's tempo range and has a superior range in total.
  • Akari sounds best when going from low to high.[2]
  • The team behind her believe she is good for beginners.[2]

Voicebank sample

Kizuna Akari VOCALOID4

Cross-Synthesis as noted:

This vocal will register for XSY, however this is a single release voicebank and there are no additional vocals included for her to utilize this function. Therefore users will have to purchase additional voicebanks not belonging to Akari for use of XSY from her XSY group "AHS".

  • From Ver.4.3.0 of the VOCALOID engine onwards, a XSY group "AHS" was added to VOCALOID. All vocals within the "AHS" group can XSY with each other. This vocal release is part of this group. If a user owns one or more vocal releases within the "AHS" group, XSY between them will open up.[3][4]
    • The group has 8 characters within it that can XSY: Yuzuki Yukari, Macne Nana, Macne Petit, Tohoku Zunko, Hiyama Kiyoteru, Nekomura Iroha, SF-A2 miki and Kizuna Akari.
    • The "AHS" group is currently the second largest XSY group within VOCALOID, having a total of 14 voicebanks that can XSY with each other. If old versions that have since been re-released are removed, there are currently 12 unique voicebanks. These are: "Yuzuki Yukari Jun", "Yuzuki Yukari Onn", "Yuzuki Yukari Lin", "SF-A2 miki", "Tohoku Zunko", "Macne Nana", "Macne Petit", "Kizuna Akari", "Hiyama Kiyoteru Natural", "Hiyama Kiyoteru Rock", "Nekomura Iroha Natural" and "Nekomura Iroha Soft".
    • In total if a user was to own every VOCALOID3 and VOCALOID4 AH-Software vocal within the "AHS" group, this offers the equivalent of 182 additional voicebanks achievable via XSY. The total tone variation offered by the combined packages comes to a theoretical 196 voicebanks in total.
  • Note that also "GWL" does not become viable for use with any V3 vocals used as the primarily vocal. This should be considered when using any vocal for XSY within the "AHS" group from V3.
  • Also note that the updated vocals that brought a VOCALOID from VOCALOID3 into VOCALOID4 provided few differences, aside from adding GWL. Therefore these updates can provide little difference when used for XSY.
