Package details as noted:

Sachiko's voicebank is designed to be faithful to that of her voice provider, the professional enka singer, Sachiko Kobayashi. This makes her a specialized product designed to give professional results.

Comes with its own Plug-in called "Sachikobushi". This adjusts VSQx files to make her sing like her provider. While this only works with her software, the created VSQx files can be used on other VOCALOIDs, though the results may not be satisfactory.

In addition, the package comes with over 400 additional voice samples.

Vocal traits as noted:
  • Offers a vivid, natural, and realistic singing voice in both a treble and bass range with a wide vocal range.
  • Being voiced by a professional enka singer, her voice is deep and mature with a more delicate timbre on higher notes.
  • The voice can produce much expression and emotion.
  • Has a particular pronunciation in the performance.
  • Both Sachiko and Fukase demonstrate successful attempts by Yamaha to capture the characteristics of famous singers.[2]
  • Sachiko is one of two Vocal package recommended to go with Fukase, the other being Gackpoid V4.[3]
  • Sachiko was highlighted as an example of a Vocal which shows superior and unique singing talent in her jerkiness handling. She was among 5 recommended vocalsby the Vocaloid staff out of the 50 vocals they sold for this reason.[4]
Phonetic notes as noted:
  • Users have reported that she has strong consonants, especially the [k'] phoneme, and her voice pitchbends very easily.
  • Short combinations with the [M] phoneme tend to produce a slight glottal stop between the consonant and the vowel (i.e. "ku" sounds like "k-hoo")
Software issues as noted:
  • Being a specialized voicebank, her voice is grounded to more traditional, slow genres.
  • Her vocals are considered "complex" to handle and is not recommended for those who are new to the software.
