## History

On October 3, 2023, Dreamtonics Co., Ltd. posted a thread on Twitter announcing four new voice databases in development for Synthesizer V Studio that were to be "coming up", providing no information apart from teasers. The second of four voice databases to be teased with a demo song within the thread was Sheena, described as a "bilingual Japanese and English female voice featuring a mature and powerful tone mixed with a melancholic, distinct timbre" with a versatile voice intended "for R&B, soul, blues, and emotive pop".

Sheena was released on October 26, 2023.

### Updates

Sheena AI v101b1 - December 18, 2023
A free update for Sheena was released following the Synthesizer V Studio 1.11.0b2 update. This implemented support for the Spanish language in the Cross-Lingual Singing Synthesis feature.

Product Information
**Optimum**

  **Genre:** R&B, soul, blues, and emotive pop
**Versions**

  **Lite Version/FLT Available?:** No  **Starter Pack Available?:** Yes  **Web Version Available?:** No
**Package details** as noted:

Sheena is a feminine Japanese and English voice database. As expected of an AI voice database, this enables her to sing with a more human-like, natural, and realistic voice.
**Vocal traits** as noted:

* Sheena's voice was described as having a mature and powerful tone, intertwined with a melancholic, distinct timbre that resonates deeply, making her an excellent choice for compositions that dwell in emotional depths.
* She was noted to be suitable for R&B, soul, blues, and emotive pop.
* With Diffusion Probabilistic Models (DPM), Sheena can sing more realistically through changes in volume and breath, further enriching singing details, making each singing unique, and providing creators with more options. Through this mode, she can use AI Retakes to create multiple "takes" of a sung section to find an ideal vocal without the need for "laborious tuning". This feature is only available in the Synthesizer V Studio Pro Editor.

**Phonetic notes** as noted:

* Phoneme format: Romaji
* Through Cross-lingual Singing Synthesis, Sheena can sing in not only Japanese and English but also Mandarin Chinese and Cantonese Chinese. Since the release of her v101b1 update on December 18, 2023, she can also sing in Spanish with this feature. This feature is only available in the Synthesizer V Studio Pro Editor.
	+ It should be noted that while Dreamtonics officially recognizes Sheena as a bilingual voice database, her default language is set to Japanese. She was confirmed to be recorded and trained in Japanese and English which helped her pronunciations in both languages. She would only be available as a Japanese voice database by default in the Synthesizer V Studio Basic Editor.

**Vocal Modes** as noted (Synthesizer V Studio Pro Editor only):

* Sheena comes with four variations:
	+ "Soft"
	+ "Clear"
	+ "Chest"
	+ "Tense"

**License agreements** as noted:

* Dreamtonics Co., Ltd.'s End User License Agreement - Japanese
* Dreamtonics Co., Ltd.'s End User License Agreement - English
