Status

The "**Status on Synthesizer V**" page acts as a guide for readers and editors alike. The "Status" page lists all the voice databases produced using Synthesizer V technology; this includes any commercial releases, announcements, developments, and projects involving the Synthesizer V franchise.

## Releases

The most commonly known Synthesizer Vs are the free or commercially sold units produced by first and third party studios. These are produced under license by Dreamtonics Co., Ltd. and are able to be downloaded for free or bought by any bidding producers through commercial outlets. Their quality and capabilities vary, as do the licensing agreements issued by the respected studios involved.

### *Synthesizer V*

A total of 8 releases were available for *Synthesizer V* in English, Japanese, and Mandarin Chinese. It should be noted that not every voice database was deemed "completed", but were available for use regardless. This version of the engine and its compatible voice databases were officially retired on July 10, 2020.

### *Web Synthesizer V*

*Web Synthesizer V* is an internet browser-integrated vocal synthesis engine developed by Dreamtonics Co., Ltd.. It was introduced as a branch off of the "SVR2" (later known as *Synthesizer V Studio*) development, but released during *Synthesizer V'*s era. *Web Synthesizer V* uses minimized database versions of vocalists and have no system requirements aside from an internet connection and a supported browser.

A total of 3 releases were available for *Web Synthesizer V* in Japanese. It should be noted that only JA-F2's vocal remains functional as of December 2021.

### *Synthesizer V Studio*

*Synthesizer V Studio* was initially introduced in July 2020 and only had Standard (initially known as "R2") voice database types available. AI voice database types were added in December that year. Lite versions were introduced as free downloads that encouraged trialing, and were single-pitched voice databases that had their own set of rules for commercial use. It should be noted that not every Synthesizer V Studio release would have both a Standard and AI voice database, and may only release as either one. They may also not have lite options available. With the introduction of rap focused voice databases included in Synthesizer V Studio version 1.9.0, Feature-Limited Trials or "FLT" editions have been released as free downloads that also encouraged trialing, These vocals may be released for a limited time or are restricted to specific engine versions.

#### *Synthesizer V Studio Standard*

A total of 16 releases were available for *Synthesizer V Studio* in English, Japanese, and Mandarin Chinese as Standard voice databases.

#### *Synthesizer V Studio Standard Lite*

This is a list compiling the Standard voice databases available for Lite.

#### *Synthesizer V AI*

A total of 48 releases were available for *Synthesizer V Studio* in English, Japanese, Mandarin Chinese, and Cantonese Chinese as AI voice databases. As of *Synthesizer V Studio* version 1.9.0, all AI vocals are capable of Cross-lingual Singing Synthesis, which allowed any AI voice database to not only sing in their base language but also fluently in the other three available languages despite not being trained nor recorded in them; starting with version 1.11.0b1, beta versions of most AI voice databases are also capable of singing in Spanish, the fifth available Cross-lingual Singing Synthesis language. Classification of multiple base languages is determined by a company's description of the product, confirmed recorded training materials, and/or separate releases. Cross-lingual Singing Synthesis is only available to the "Pro" version of the editor and only works with full releases.

#### *Synthesizer V AI Lite*

This is a list compiling the AI voice databases available for Lite.

#### *Synthesizer V AI Feature-Limited Trials*

This is a list compiling the AI voice databases available for Feature-Limited Trials.

## Current Developments

### Announced Engine Plans

The following is a list of plans announced for the future of the Synthesizer V franchise.

* On July 18, 2023, Dreamtonics announced that they began to adapt Reinforcement Learning with Human Feedback (RLHF) to Synthesizer V AI's pitch model. AI Retakes were introduced since version 1.7.0, which randomized generation and allowed users to choose their preferred rendition from a list of options. Building upon this, a pair of singing samples would be generated and presented to the listener, who then compared the two and rated them. The ratings would inform the model's learning until the feedback loop allowed for it to refine the voice generation based on the listener's preference. RLHF-enhanced models were reported to be an improvement over the diffusion model baseline across languages according to internal feedback. RLHF-enhanced models were expected to produce fewer off-tune notes, with singing expressions that were more relevant to the context and better use of vibrato. RLHF-enhanced pitch models were expected to be part of the next update.
	+ In addition, there were plans to extend RLHF to rap vocals and voice timbre.
	+ Version 1.10.0b2 released on September 28, 2023, which included adjustments based on numerous issues reported by users (such as Vocal Modes seeming less distinct in the previous 1.10.0b1 update), a new generation of pitch models that offered greater accuracy in voice timbre production and reduction in mispronunciations, a new feature in the Note Properties Panel that allowed for an even division of a note into multiple syllables, and an intuitive UI adjustment for when the Piano Roll toolbar's space becomes limited.
* On September 19, 2023, Dreamtonics announced that they would be part of the Music China in Shanghai event at the Shanghai New International Expo Center as an exhibitor to showcase Synthesizer V Studio, including exclusive previews of upcoming features. The event was set to run from October 11 to October 14.
* On November 5, 2023, Eclipsed Sounds, LLC announced that, with guidance from Dreamtonics for its research and development, Synthesizer V Studio will add support for Spanish as a Cross-Lingual Synthesis language in a future update, with SAROS becoming the first vocal to receive it before spreading to other voice databases. Dreamtonics later confirmed this development on a later tweet.
	+ This language was added on version 1.11.0b1, with SAROS as the only vocal supporting it back then.
	+ With version 1.11.0b2, support for this language was expanded to other voice databases.

### Announced Vocals

These are Synthesizer V voice databases known to be in production. Their status and licensing are unknown, but most are presumed to have commercial licenses.

## Restricted access

These are vocals that producers have or currently have limited access to.

### Retired Vocals

There are some Synthesizer V voice databases that were available commercially that have now been removed from sale or will be removed from sale in the near future. Vocals that have seen retirement may continue to be sold for some time after their initial retirement; however, they are on limited supply and will sell only while the stock lasts. Their usage is limited to those who are able to access these vocals before or since their retirement, as no new stock has been released containing their vocals.

Please note that when a new version of the engine is released, there is a risk of support for older versions being removed. They may or may not be removed from sale.

### Beta/Prototype voice databases

These vocals exist but are only prototypes and may not become commercial products.

Throughout 2022, Cangqiong Synthesizer V Plus and Muxin Synthesizer V Plus received multiple examples demonstrating their capabilities as Standard-trained AI voice databases, including the Cross-lingual Singing Synthesis function. However, news about the development and future releases in general for all six characters were not available. On September 29, in response to a fan's question about whether the Plus versions of the six voice databases would be released soon, Quadimension wrote that it was probably not likely due to the qualities being unfit for commercial use. On November 22, in response to a fan, Ddickky confirmed that the Plus series of voice databases were created with the intention of demonstrating the effects of training AI with Standard voice databases and were not meant to be released. The voice databases were sent to shareholders as a technology demonstration and not as a full product update. As these voice databases were to show the effects and technology of splicing AI training, they could not be noted as "Synthesizer V AI" as they would affect the brand quality of AI voice databases, thus the need of calling these "Synthesizer V Plus".

## Rumour mill

These vocals are rumoured or hinted to be released but their status has not been made official.

### Possible future voice databases

This section contains hints, confirmations and suggestions put out by Synthesizer V studios.

 CUL, REV, WhiteCUL, and other concepts
It was confirmed that after ROSA is released, an official livestream would be launched for announcements. Depending on if ROSA sells well, REV may also be considered for development. REV later released as a DeepVocal voicebank on May 24, 2021, with HirotoP voicing him. He is being considered for a commercial voicebank depending on his popularity, and should it happen, a proper voice actor or singer would be assigned to him.
On June 3, 2022, ROSA tweeted that she and WhiteCUL would be performing at the *柚子花主催LIVE -Planet Station- STAGE.3* online concert on June 19, however, WhiteCUL's character design would not be shown. On the day of the concert, it was later clarified that the singing voices for ROSA and WhiteCUL were performed by their voice providers rather than using singing voice synthesizers. HirotoP hoped that the performances would give listeners an idea of what an AI singing voice database would sound like. It is currently unknown if WhiteCUL would be receiving a singing voicebank as, at the time, only ROSA was confirmed to be receiving a Synthesizer V AI voice database.

### Awaiting further confirmation

The following are possible upcoming voicebanks whose statuses are **not** yet clarified, or they are vocal developments that were announced but have not had any updates about their statuses within the last six months.

### Unreleased or assumed cancelled

This section contains unreleased voice databases that are likely or assumed to be cancelled in the absence of further information.

Xingchen Infinity was later announced on August 25, 2021. This was planned to be a Synthesizer V AI voice database. It is currently unknown if the English voice database would still be produced, especially since Cross-lingual Singing Synthesis (introduced since Synthesizer V Studio Pro 1.5.0) allows AI voice databases to sing in all four officially-supported languages (Japanese, English, Mandarin Chinese, and Cantonese Chinese) with a fifth language (Spanish) coming soon.

### No longer in consideration

The following are vocal developments that were once considered (or rumored to be considered, based on hints and suggestions) for Synthesizer V but were later dismissed in favor of other vocal synthesizer engines.

 On May 17, 2021, Yuuma tweeted that Kemonone Row and Shiki Taigen were expected to have commercial voicebanks developed on a software that would support English input. It was noted that the English voicebanks would be based on Japanese pronunciation. The platform was not confirmed at the time. In regards to Row's name, Yuuma noted that he wasn't sure which would be better for a person's name as he didn't know enough English to make a decision, leaving this to fans to give suggestions. This later led to Yuuma tweeting that the name would be changed to "Rowen Shiki", Row's real name, after the development of a commercial voicebank was decided. It would serve to unify with the family name "Shiki", which was the same as Shiki Taigen, Row's great-grandfather.
Later on July 5, Yuuma expressed interest in creating a Synthesizer V AI database for Row, though a crowdfund would be necessary to produce it. He later asked overseas fans on July 7 if Row's voicebank should be on Synthesizer V, and if so, a Standard voice database was considered due to budget. Synthesizer V was not a final decision, but it was confirmed to still be a consideration. A decision on crowdfunding would be dependent on support and encouragement from fans. The estimated budget would be based on previous successful Synthesizer V crowdfunds.
On July 26, 2022, Yuuma announced that Shiki Rowen was now being recorded for an AI singing voicebank which would be first released for free on the NNSVS engine; in response to inquiries by fans, he said that SynthV was no longer in consideration but that other commercial platforms were being considered. Budgetary reasons (allocating everything for A.I.VOICE and blanking out AI singing synthesis) were cited for the dismissal of SynthV as a platform for Rowen.
On December 21, 2023, Yuuma tweeted that Rowen would get a new singing voice on a commercial software (as well as a new commercial text-to-speech voicebank), but did not name any specific synth engines. After a fan speculated a day later whether the singing vocal would be on either VOCALOID6 or Synthesizer V AI and whether the talking vocal would be on either A.I.VOICE2 or VOICEPEAK, Yuuma assured on December 25 that the engines were not related to AH-Software Co. Ltd. at all, thus ruling out SynthV and VOICEPEAK as possibilities. Instead, he declared that the synthesis platform would be "still a secret."

"不过另一点是，不光声源觉得ai和自己太像，我也觉得如果这么像声源而非角色之前的声库。不是很合适。星尘一定要做是因为v4性能过于差，所以硬顶着声音变化的反对也做了。而其他几个角色是sv2带拼接式，性能过得去，那做了ai产生与星尘类似的声音变化风波，在外加商业角度（卖声库）不是那么挣钱，你能理解我逻辑了吧。"
