## History

On June 30, 2022, a demonstration of the new upcoming High Dynamics Voice Models (HDVM) feature was uploaded to Dreamtonics Co., Ltd.'s YouTube and bilibili accounts. An unnamed female English voice database was shown but it was not confirmed who this vocalist was at the time.

On September 22, Dreamtonics revealed two new voice databases in progress: a feminine English voice known as "Natalie" and a masculine Japanese voice known as "Yuma". Each vocal had one demo featured in their debut video and a brief description of their voice databases. Both were confirmed to be compatible with the Cross-lingual Singing Synthesis, Vocal Mode, and AI retake functions. On October 7, Natalie and Yuma officially released as digital copies, with starter packs available from Dreamtonics and AH-Software Co. Ltd.. At some point after Natalie was revealed or released, when viewing the HDVM demo on bilibili, with the "bullet comments screen" function turned on, the portion with the new English female voice would have Natalie's demo pop up on screen, confirming that she was this vocalist.

### Updates

Natalie AI v103b1 - November 10, 2022
A free update for Natalie was released following the Synthesizer V Studio 1.8.0b1 update. This enables her to use the new Diffusion Probabilistic Models (DPM) feature.

Natalie AI v103 - November 24, 2022
Final version update compatible for Synthesizer V Studio 1.8.0 and enables Natalie to use the new Diffusion Probabilistic Models (DPM) feature if the beta version was not installed previously.

Natalie AI v106b1 - April 18, 2023
A free update for Natalie was released following the Synthesizer V Studio 1.9.0b1 update. This implemented the new rap feature available for the English and Mandarin languages. Cantonese Chinese was added to the Cross-lingual Singing Synthesis feature as well as general improvements to the overall function, resulting in more accurate pronunciation that sounds closer to a native speaker when singing foreign words.

Natalie AI v106b2 - May 23, 2023
A free update for Natalie was released following the Synthesizer V Studio 1.9.0b2 update. This version of the vocal allowed for compatibility with the engine's second beta, which focused on rectifying several design issues identified by the user base in the 1.9.0b1 post-release survey.

Natalie AI v106 - June 21 2023
Final version update compatible for Synthesizer V Studio 1.9.0 and enables Natalie to use the rap feature (English and Mandarin Chinese only) and allow for Cantonese Chinese Cross-lingual Singing Synthesis if the beta versions were not installed previously.

Natalie AI v107b1 - August 2, 2023 A free update for Natalie was released following the Synthesizer V Studio 1.10.0b1 update. This enhanced pitch generation by utilizing Reinforcement Learning from Human Feedback (RLHF), translating to fewer off-key errors, making better use of vibrato, and creating more expressive transitions between notes. This also allowed for the use of the new "Enhancement" slider in the AI Retakes panel, which controlled the level of changes introduced by RLHF. For Synthesizer V Studio Pro users, feedback submission was enabled, allowing users to consensually share their preferred takes with only Dreamtonics for research and development purposes, where models trained with this feedback would be deployed in future voice database updates. Users may also opt out of this feature if undesired.

Natalie AI v107b2 - September 28, 2023 A free update for Natalie 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.

Natalie AI v107 - October 19, 2023 Final version update compatible for Synthesizer V Studio 1.10.0 and enables Natalie to use Reinforcement Learning from Human Feedback (RLHF) as well as other enhancements (as listed in v107b1 and v107b2's notes) if the beta version was not installed previously.

Natalie AI v108 - October 26, 2023 A free update for Natalie was released that added support for the Japanese language to the rap feature.

Natalie AI v109b1 - December 18, 2023
A free update for Natalie 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.

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.
