## History

On July 12, 2018, VOCALOID5 was officially launched and Haruno Sora, voiced by Japanese voice actress and singer, Kikuko Inoue, made her debut as an upcoming VOCALOID5 product with two singing voicebanks ("Natural" and "Cool") and as an upcoming speech voicebank for VOICEROID2. She was released on both engines on July 26.

### 2023

On May 18, 2023, Haruno Sora was announced to be in production for Synthesizer V Studio as a singing AI voice database and as a speech voice library for VOICEPEAK. A silhouette of a new design was shown and it was confirmed that her Synthesizer V voice database would be shown at VVV MUSIC LIVE on June 25. She would be performing a self-cover of "Koi no Jumon wa Sorasora" by EHAMIC, which originally released in July 2018 and served as a demo for her VOCALOID5 voicebanks. On the day of the performance, it was revealed that she sang two songs: the previously mentioned "Koi no Jumon wa Sorasora" and "Rera", a song that was originally sung by Nekomura Iroha.

On July 18, to commemorate Sora's fifth anniversary and character birthday, it was announced that Kikuko Inoue would be attending AH-Software Co. Ltd.'s next livestream scheduled for July 26. Information about Sora's Synthesizer V and VOICEPEAK development would be presented as well. On July 24, AH-Software revealed Sora's new designs and demonstrations. The Synthesizer V outfit was designed by Hasegawa Umi and the final version was illustrated by Umetani Atarō. Pre-orders for Sora's Synthesizer V and VOICEPEAK libraries opened and it was confirmed that she would release on August 24. Sora released on August 24 as expected. Her Lite version was released a week later on August 31.

### Updates

Haruno Sora AI v101b2 - September 28, 2023 A free beta update for Haruno Sora was released following the Synthesizer V Studio 1.10.0b2 update, which was the second beta version following version 1.10.0b1 that introduced enhancements to voice databases and integrated the latest user feedback via Reinforcement Learning from Human Feedback (RLHF). Regarding the editor, numerous reported issues were addressed for a more fluid experience. A new generation of pitch models were trained using the extensive feedback from users over the past month, and the new models offered greater accuracy in voice timbre reproduction, as well as a reduction in mispronunciations. Dreamtonics also focused on issues from the previous beta release that made Vocal Modes seem less distinct on certain vocals, ensuring clearer differentiation in the 1.10.0b2 update. The latest update also introduced a new feature in the Note Properties Panel that allowed for even division of a note into multiple syllables, proving to be a useful tool for songs with faster tempos.
For Sora specifically, she was the only new vocalist since the release of Synthesizer V Studio 1.10.0b1, thus, she did not have a "b1" update available like the past Synthesizer V AI vocalists.

Haruno Sora AI v101 - October 19, 2023 Final version update compatible for Synthesizer V Studio 1.10.0 and enables Haruno Sora AI to use Reinforcement Learning from Human Feedback (RLHF) as well as other enhancements (as listed in v101b2's notes) if the beta version was not installed previously.

Haruno Sora AI v102 - October 26, 2023 A free update for Haruno Sora was released that added support for the Japanese language to the rap feature.

Haruno Sora is a feminine Japanese voice database based on the singing style of Kikuko Inoue. As expected of an AI voice database, Sora can sing with a more human-like and realistic voice.
**Vocal traits** as noted:

* Sora can express a wide range of intonations, from a soft and gentle voice quality to a powerful and cool style in the lower range.
* With Diffusion Probabilistic Models (DPM), Sora 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.
	+ This does not apply to the Lite version.

**Phonetic notes** as noted:

* Phoneme format: Romaji
* Through Cross-lingual Singing Synthesis, Sora can sing in not only Japanese but also in English, Mandarin Chinese, and Cantonese Chinese. This feature is only available in the Synthesizer V Studio Pro Editor.
