History

On May 25, 2022, Dreamtonics announced that a new voice database would be introduced on May 26 at 17:00 in China. The announcement was paired with a short poem that was themed around the idea of echoing one's inner feelings and unspoken heart. The new vocal was introduced through a demo song and was announced to be a female Mandarin Chinese voice database known as "Feng Yi". She was expected to release simultaneously on Dreamtonics's Taobao and International stores on May 27. From then until June 11, she was to be 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. According to Mouzhize, the tuner of "Gùshì de Zuì Jiéwěi", Feng Yi was confirmed to have at least three Vocal Mode variations: Power, Chest, and Open. In the "Líhuā Sòng" cover, Mouzhize confirmed that Feng Yi also had "Opera" as one of the Vocal Mode variations.

On May 27, Feng Yi was released and made available on the Dreamtonics Taobao store. Though it was noted in their bilibili article that she released simultaneously on the Dreamtonics International Store as well, the official Twitter account instead announced that she would be made available on May 29 at 12 PM JST instead. 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, Feng Yi 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 her 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 Feng Yi (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 Feng Yi, Qing Su, Mo Chen, and An Xiao, as well as Yuma and Natalie, the newest Dreamtonics vocals.

Updates

Feng Yi AI v103 - July 21, 2022 

A free update for Feng Yi AI was released following the Synthesizer V Studio 1.7.0 update. This enables her to use the new High Dynamics Voice Models and AI Retakes features.

Feng Yi AI v104b1 - November 10, 2022 

A free update for Feng Yi was released following the Synthesizer V Studio 1.8.0b1 update. This enables her to use the new Diffusion Probabilistic Models (DPM) feature.

Feng Yi AI v104 - November 24, 2022 

Final version update compatible for Synthesizer V Studio 1.8.0 which enables Feng Yi to use the new Diffusion Probabilistic Models (DPM) feature if the beta version was not installed previously.

Feng Yi AI v105b1 - April 18, 2023 

A free update for Feng Yi 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.

Feng Yi AI v105b2 - May 23, 2023 

A free update for Feng Yi 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.

Feng Yi AI v105 - June 21 2023 

Final version update compatible for Synthesizer V Studio 1.9.0 which enables Feng Yi to use the rap feature (English and Mandarin Chinese only) and allows for Cantonese Chinese Cross-lingual Singing Synthesis if the beta versions were not installed previously.

Feng Yi AI v106b1 - August 2, 2023 

A free update for Feng Yi 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.

Feng Yi AI v106b2 - September 28, 2023 

A free update for Feng Yi 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.

Feng Yi AI v106 - October 19, 2023 

Final version update compatible for Synthesizer V Studio 1.10.0 which enables Feng Yi to use Reinforcement Learning from Human Feedback (RLHF) as well as other enhancements (as listed in v106b1 and v106b2's notes) if the beta version was not installed previously.

Feng Yi AI v107 - October 26, 2023 

A free update for Feng Yi was released that added support for the Japanese language to the rap feature.

Feng Yi AI v108b1 - December 18, 2023

Feng Yi AI v108 - April 4, 2024 

Final version update compatible for Synthesizer V Studio 1.11.0 which enables Feng Yi to sing in Spanish through Cross-lingual Singing Synthesis if the beta version was not installed previously.

Package details as noted:

Feng Yi is a feminine Mandarin Chinese voice database that works best in the mezzo-soprano range, and was noted to offer a good complement to the lower-ranged Qing Su. She was described to be an emotionally charged singer with a silky smooth yet firm and powerful voice. As expected of an AI voice database, this enables her to sing with a more human-like and realistic voice. Like Mo Chen and An Xiao before her, she was marketed to promote the new functionality and experience of Synthesizer V Studio 1.6.0's Vocal Mode.

Vocal traits as noted:

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.

Phonetic notes as noted:

• Phonetic format: X-SAMPA
• Through Cross-lingual Singing Synthesis, Feng Yi is able to sing in not only Mandarin Chinese but also in English and Japanese. Since the release of her v105b1 update on April 18, 2023, she can also sing in Cantonese Chinese with this feature; since her v108b1 update on December 18, she can also sing in Spanish with this feature. Cross-lingual Singing Synthesis is only available in the Synthesizer V Studio Pro Editor.

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

• Feng Yi comes with six variations:
  • "Chest"
  • "Power"
  • "Open"
  • "Opera": Modeled after Peking Opera styled vocalization.
  • "Soft"
  • "Airy"

System requirements as noted:

• OS: Microsoft Windows 11 / 10 / 8.1 (64 bit) and up; macOS 10.11 (El Capitan) and up; Ubuntu 18.04 (64 bit) and up
