## History

On May 4, 2022, An Xiao was suddenly introduced with one demo on bilibili and was released simultaneously on the official Dreamtonics taobao shop and International Store. From then until May 19, he was sold at a discounted price of 479 yuan as a standalone and 899 yuan as a bundle pack with the Synthesizer V Studio editor on taobao.

On June 13, Dreamtonics announced that they launched a new official store for the Chinese market built on WeChat's Mini Program. Users would be able to purchase the Synthesizer V Studio Pro editor and Dreamtonics' vocals through the application in a convenient manner, enjoying the automatic real-time distribution shopping experience. From June 13 to July 13, users were able to take advantage of unlimited 10% off coupons in the new store. It was later clarified that the decision to open this new shopping option was made due to Taobao's new restrictions on the sales of virtual goods as of April 2022, especially for restrictions on shipments without logistics since virtual goods would need to be delivered via email.

On July 21, An Xiao was one of the AI voice databases to receive an update for HDVM compatibility (a feature introduced in Synthesizer V Studio Pro 1.7.0, also released the same day). However, some users complained about unstable voice-quality results when re-rendering in 1.7.0 projects saved under earlier versions of the editor that made use of his voice database (after updating it to v103). On July 22, Dreamtonics explained that by default, the AI Retakes feature favors "rich timbre and expressions over smooth and stable vocalization", resulting in inconsistent behavior relative to previous versions; as a workaround to stabilize the voice output, they offered these steps below:

* Empty the selection.
* Open AI Retakes panel, go to Timbre tab.
* Under Takes -> Global Settings, reduce Expressiveness.

Responding to requests from users, Dreamtonics made available for download that same day rolled-back versions of An Xiao (as well as other affected AI voice databases) by logging in to their store download website.

On October 7, it was announced that AH-Software Co. Ltd. would begin distributing digital versions of An Xiao, Qing Su, Mo Chen, and Feng Yi, as well as Yuma and Natalie, the newest Dreamtonics vocals.

Final version update compatible for Synthesizer V Studio 1.8.1 and improves the neural vocoder for all male vocals, including An Xiao, which results in an enhanced sound quality in the bass range.

An Xiao AI v106b1 - April 18, 2023
A free update for An Xiao 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.

An Xiao AI v106b2 - May 23, 2023
A free update for An Xiao 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.

An Xiao AI v106 - June 21 2023
Final version update compatible for Synthesizer V Studio 1.9.0 and enables An Xiao 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.

An Xiao AI v107b1 - August 2, 2023 A free update for An Xiao 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.

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

An Xiao AI v107 - October 19, 2023 Final version update compatible for Synthesizer V Studio 1.10.0 and enables An Xiao 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.

## Voice Database Information

### Voice Databases

Product Information
**Versions**

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

An Xiao is a masculine Mandarin Chinese voice database. As expected of an AI voice database, this enables him to sing with a more human-like and realistic voice. He was noted to have "a full and bright voice with no lack of passion". Like Mo Chen before him, he was marketed to promote the new functionality and experience of Synthesizer V Studio 1.6.0's Vocal Mode.
**Vocal traits** as noted:

* According to Dreamtonics, he has a flexible range that would provide high-quality results in his tenor and bass tones.
* He was advertised to be capable of "bringing an impressive level of emotion and expression".
* As per the Synthesizer V Studio 1.7.0 update launched on July 21, 2022, through High Dynamics Voice Models (HDVM), which later migrated to Diffusion Probabilistic Models (DPM) per the 1.8.0b1 update on November 10, AI voice databases may use AI Retakes to create multiple "takes" of a sung section with variations in pitch, dynamics, and timbre. This replicates the randomness of human vocalists, adds a more realistic feel, and allows users to find an ideal vocal without the need for "laborious tuning." This feature is only available in the Synthesizer V Studio Pro Editor.

Certain users were invited to create songs using earlier versions of the voice database and release the songs in sequence after the product's release as a complement to official demo tracks. Although this did not apply to An Xiao when he first released, he may be present as a main vocalist in examples featuring the other Dreamtonics products, which would be added to this demo table. It should also be noted that certain songs may not be involved with the early invitation and were added based on the company's preference.
