What Is AI Yuzuki?
AI Yuzuki Yukari is a VOCALOID6 voicebank that updates the long-running Yuzuki Yukari character to the latest singing synthesis engine. The voicebank features the voice of Japanese voice actress Chihiro Ishiguro (石黒千尋), who has provided Yukari’s voice since her original VOCALOID3 release in December 2011 .
The character Yuzuki Yukari was created by VOCALOMAKETS, a creator team of seven Vocaloid producers, and is managed by BumpyFactory. The name “Yuzuki” derives from combining the words for “connecting” and “moon,” with the English concept being “She unites you all with her voice” .
The AI Yuzuki release represents Yukari’s return to the VOCALOID platform after approximately ten years since her VOCALOID4 release in March 2015. Interestingly, the VOCALOID6 version is developed and distributed by Internet Co., Ltd. rather than AH-Software, who handled her VOCALOID3 and VOCALOID4 releases .
How AI Yuzuki Works
The VOCALOID AI Engine
AI Yuzuki Yukari is specifically optimized for VOCALOID AI technology, which represents Yamaha’s latest approach to singing synthesis. Unlike traditional VOCALOID voicebanks that rely on concatenative synthesis, VOCALOID AI uses deep learning techniques to generate more natural and expressive vocals .
Yamaha describes the result as “featuring the relaxed tone of voice with a nice luster,” able to “sing with richer and wider variations, from human-like realistic vocal tone to futuristic robot voice” . This range is achieved through the AI engine’s ability to model vocal characteristics more flexibly than previous concatenative methods.
Style Presets
The voicebank includes 10 style presets that users can apply within the VOCALOID6 editor :
- Yukari Chorus: Layered vocal effect
- Yukari Default: Standard voice
- Yukari Drive Hard: Aggressive, distorted tone
- Yukari Drive Soft: Milder distortion
- Yukari Dry: Unprocessed, close sound
- Yukari Robot Dry: Robotic without effects
- Yukari Robot Wet: Robotic with reverb
- Yukari Wet: Reverb-heavy tone
- Yukari Whisper Dry: Whispered without effects
- Yukari Whisper Wet: Whispered with reverb
These presets allow producers to quickly shift between dramatically different vocal characters without manual editing.
VOCALO CHANGER Integration
AI Yuzuki Yukari supports the VOCALO CHANGER feature, which allows creators to reproduce their own singing style and lyrics using the voicebank. This function analyzes a user’s vocal performance and applies Yukari’s voice to it, creating a hybrid that combines the user’s phrasing with Yukari’s tone .
Multi-Language Support
The voicebank supports fluent singing in Japanese, English, and Chinese, allowing a single voicebank to handle multilingual projects without switching between different libraries .

Who Should Use AI Yuzuki
Vocaloid producers and music creators who already work with VOCALOID or want to explore the latest AI-based singing synthesis. The voicebank offers a familiar character with updated capabilities.
Yuzuki Yukari fans who have followed the character through her VOCALOID3, VOCALOID4, CeVIO AI, and other iterations. The AI version represents a significant technical upgrade while preserving her core vocal identity .
Producers working in multiple languages who need a single voicebank for Japanese, English, and Chinese projects .
Users seeking natural-sounding AI vocals who want the flexibility to shift between realistic and robotic styles through the included presets .
Beginner producers may find the included VOCALOID6 Editor Lite sufficient for initial projects, though the 2-track limitation will require upgrading to the full editor for more complex arrangements .
Common Mistakes and Cautions
Assuming the voicebank works standalone. AI Yuzuki Yukari requires VOCALOID6 Editor or the included Editor Lite. The voicebank alone cannot produce sound .
Overlooking the single-computer license. The license covers one computer only. Users who need both Windows and Mac support must purchase additional copies .
Confusing AI Yuzuki with other Yukari versions. Yukari has multiple voicebanks across different platforms including VOCALOID3, VOCALOID4, CeVIO AI (as Yukari Rei), VoiSona, A.I.VOICE, and Seiren Voice . AI Yuzuki specifically refers to the VOCALOID6 release.
Underestimating system requirements. VOCALOID6 requires a reasonably modern CPU and at least 8GB of RAM. Older systems may struggle with performance .
Forgetting the Editor Lite limitations. The included Editor Lite supports only 2 tracks in standalone mode. Producers with complex arrangements will need to purchase the full VOCALOID6 Editor .
