Draft:Synthesizer V

Synthesizer V Studio (also known as Synthesizer V, or Synth V) is a singing voice synthesizer (SVS) developed and distributed by Dreamtonics Co., Ltd. which was first released in December 2018. The software is designed for the creation of artificial singing vocals for music production but is also widely used for artificial speech. Officially supported languages include English, Japanese, Mandarin Chinese, Cantonese Chinese, and Spanish. It became popular among SVS enthusiasts after the release of Synthesizer V AI, which is notable for its use of neural networks, which aid the software in producing more natural sounding results than the traditional concatenative methods used in most SVS programs.

Synthesizer V Editor (Generation 1)
Currently known as Generation 1, R1 or gen1, Synthesizer V Editor was released by Kanru Hua in August 2018, selling itself as a simple-to-use modern vocal synthesizer.

History
Although Synthesizer V's first line of code has been dated back to 2015, as part of the proto-proto libllsm, which would become part of SynthV and the UTAU resampler Moresampler, the first signs of official development began in 2017, with the release of a track titled "Synthesizer V Demo" by Kanru Hua on SoundCloud. It features three voices: ENG-F1 (later released as Eleanor Forte) singing "Young and Beautiful," JA-F1 singing "Yuki no Hana," and MAN-F1 singing "Mo Li Hua." The project was unveiled to the public on the 1st of December 2017 and was well received.

August 19th, 2018, a technical preview version of the software was released for user feedback. December 24th, the official production version was released, alongside AiKO and Genbu. The software received updates until its retirement in July 2020, due to the release of Synthesizer V Studio.

Web Synthesizer V
Web Synthesizer V is a browser-run stripped down version of Synthesizer V Studio, initially released in the 31 of December 2019. It exists as an avenue for users to test new updates before they are applied to the main engine. It only ever received one update, on July 22, 2020 the software received a bigger selection of voices and support for different browsers.

Synthesizer V Studio (Generation 2)
Synthesizer V Studio, also known as generation 2, R2 or gen2, is the current release of Synthesizer V. It is available in 2 versions, "Synthesizer V Studio Pro" initially released July 10, 2020 and "Synthesizer V Studio Basic" initially released July 30, 2020. It features a completely reworked engine, which combines sample-based synthesis and AI machine learning. It was through this version that Synthesizer V AI (also known as Generation 3) was released, an update which allowed certain voices to take full advantage of the software's AI technology, which has since become Synth V's most popular feature.

Synthesizer V Basic and Synthesizer V Studio differ in that Basic is a stripped down version of the engine available for free. Basic lacks access to some of Pro's features, only allowing the creation of 3 tracks per project, and prohibits commercial use, requiring a user to upgrade to Pro should they wish to sell any work made with the engine. Voices sold for Synthesizer V have a similar model, providing "Lite" versions of voice libraries that are available for free, but are lower quality, have fewer features, and do not permit users to sell work made with them.

History
The software was initially unveiled by AH-Software Co. Ltd. on their official Twitter account June 26, 2020, with the voices of Saki and Kotonoha Akane & Aoi. The software was released next month, on July 10, 2020 to Chinese users through Beijing Photek S&T Development Co., Ltd.'s Taobao and on July 15, for international users through AniCUTE. Later on July 30, the Basic version was released for Japanese users through AH-Software Co. Ltd, and the next day, it was made available on Dreamtonics' official website.

On December 25th, 2020 AI support was implemented into Synthesizer V Studio through Synthesizer V AI, alongside the release of Saki AI. From this point voices would be categorized as Standard Voices, and AI Voices, according to whether or not they use Synth V AI.

On December 23rd, 2021, cross-lingual synthesis was implemented into Synthesizer V Studio for all AI voices, effectively rendering all AI voices trilingual regardless of their native language, allowing them to sing in Japanese, Chinese or English. This feature is exclusive to the paid versions of AI voices running on Synthesizer V Pro. Some voices, like Stardust Infinity, have additional recordings in more than one language, as this allows for more fluent results when using cross-lingual synthesis.

On February 2, 2022, AH-Software Co. Ltd. announced that Synthesizer V Studio sales had been exceeding the their expectations, marking the software's growth in popularity.

On February 27th, 2023, Dreamtonics announced plans to support Cantonese cross-lingual synthesis, a dedicated synthesis mode that allows vocalists to rap, and two new vocalists dedicated to rapping. As of June 2023, all features related to rap are only available when a vocalist is using English or Mandarin Chinese, however Dreamtonics has announced that they intend to add Japanese compatibility to the feature in a future update.

On November 5th, 2023, third-party developer Eclipsed Sounds announced that Synthesizer V would support Spanish cross-lingual synthesis with the release of version 1.11.0 of Synthesizer V AI. This was the first time that support for a language had been implemented by a third-party developer in cooperation with Dreamtonics. Th
