MEDIUM⁵ Synthesizer V Plus/AI Versions

I’m genuinely unsure if there was ever a dedicated thread for these vocal updates in general. I’ve seen them here and there within the Cross-lingual Singing Synthesis announcement thread, but that’s about it. I figured starting a thread all in one place just for the latest development and demos of these versions would be good to have.

This is about the AI voice databases for the other 6 characters from Quadimension (Beijing Photek) that are currently available as Standard only. For a bit of background, these were announced since December 23, 2021. Details included that the 6 would be updated especially to support Japanese and English due to Cross-lingual Singing Synthesis being implemented in the 1.5.0 update and the only way the 6 could use that was if they had AI type databases since Standards couldn’t use it. These AI databases were noted to be trained by the Standard versions. The vocals are currently going through beta testing to ensure satisfactory results.

As of now, only Cangqiong and Muxin have examples shown in public, with both being labelled as “Synthesizer V Plus”, which is referring to these AI versions. Here’s a list of the demos and samples for both of them, both directly hosted on the official MEDIUM⁵/Xingchen/Haiyi accounts and off (only posted to the beta testers’ accounts). I’ll skip the short versions if they ended up getting full ones and post them in release order.

Things don’t seem to be looking too good for these Plus versions. A fan asked if these would be releasing soon and Quadimension responded that it’s probably not likely. The response was given on September 29 this year.

Oh wow. It did seem pretty ambitious to try and make AI voices out of Standard ones without actually recording new samples, but this is still disappointing news, I was really hoping for a Shian update :pensive:

Noooo my dreams or Cangqion Plus!!

Will they try to push the project forward though? No harm in re-recording some things…

We don’t really have solid answers as of right now. Only time will tell

Hi everyone, I’m currently doing massive edits on SynthV wiki, so I’m just popping in real fast about what was recently revealed.

On an article released by Ddickky, one of the fans asked in the comments about the status of the Plus voices and Ddickky basically responded that these databases were created to demonstrate the effects of training AI with Standard databases. These were not meant to be released to the public and were only sent to shareholders to demonstrate the technology, not as a product update. Because of the way they were produced, they couldn’t be called Synthesizer V AI voice databases as this would affect the brand quality of AI voice databases, hence why they’re known as Synthesizer V Plus.

Direct comment here:

Unfortunately, we don’t know if they’ll pursue full AI voice databases in the future or not, or about their next projects for Synthesizer V in general if any (not that was pointed out to me nor what I can read).

Got something new to share today. Ddickky was responding to a few users on his bilibili post about AI voice databases.

There’s a bit to talk about, so to sum up:

  • The standard-trained AI voice databases were promoted with Xingchen Infinity. The VAs were invited at the same time in the prior year.
  • There were some concerns about the AI voice databases sounding too close to the VAs. The VAs were concerned that their jobs would be “stolen”. There was also mention of procrastination on their end as well until more recently. Basically, there’s been some reluctance to cooperate in producing AI voice databases.
  • There’s concern that the AI versions would not sound like the R1 and R2 Standard versions. For additional context, there was some resistance to Xingchen Infinity because she didn’t sound like her original VOCALOID4 version. Xingchen needed to be updated because the V4 version performed poorly, so it needed to be launched even under the pressure of changing the singing voice style. For the other cast members, changing the voice style was always uncertain. There may be reactions of resistance similar to what Xingchen Infinity had gone through.
  • There was a lack of motivation due to commercial sales of voice databases never being so profitable.
  • Regarding commercialization, there’s no solid plan right now, but it might be similar to Xingchen Infinity. Because the tech workload and input costs were different, they may be sold for hundreds of yuan, which was cited to be another reason that he thinks that they might not be suitable commercially.
  • The good news? We are probably seeing the production of Chiyu AI and Minus AI, both expected for this year if there are no delays and/or issues.
  • Reminder that the Plus versions should not be expected. These are for private use.
  • Currently, no mention of Shian, Cangqiong, Haiyi, and Muxin.

Not much news, but Chiyu’s voice provider, Youmao (UNEKO) wanted to assure everyone that Chiyu AI definitely will be completed as far as she knows.

I think there is something else you should mention, especially for lovers that does not know “Dickky” very well:

  • The “Dickky”, boss of MEDIUM5, seemed have already lost interest on developing/renewing voice banks, his recent posts are mainly about body-building;
  • Dickky decided not to publish any more official albums of MEDIUM5 after the one in process being done (everytime he made official albums, he loss money :rofl:);
  • The developing of a game related to MEDIUM5 [CG video link] has been stopped due to the lack of money;
  • Dickky has lost a LOT of money due to bad commercial decision, so the “minor” voicebanks (Shian, Cangqiong, Haiyi, and Muxin) may not be renewed to AI version;
  • Do NOT believe Dickky can seize correct commercial opportunity in future;
  • !!!Dickky always post self-contradictory statements, so do not trust in his words without think twice.

Let me translate the article (published on 2023-march-21th,night) into English:

zh-cn:再发一条吧今天,明确一点说对大家都好些。赤羽AI(Chiyu AI)至少目前在我所了解的信息流里是一定会做的,我和我的家人朋友们也随时都做好了准备去配合完成。进度上慢:一是因为工作很忙、二是因为有一些别的考量在声库里;我们需要先试做一个版本再去把控最终质量应该往什么样的方向去调整

Let me post another article today. It’s better for everyone to be clear that: according to the information I got until now, Chiyu AI is definitely going to be produced, my family, friends and me myself are always ready to work with it. The progress is slow because we’re very busy and because there are some other considerations in the voicebank. We need to make a demo version of voicebank, and adjust the feature and quality accordingly before publish the final version.


In my point of view, the AI version may not sounds like Youmao (UNEKO) that much as former versions did. There exists lots of praise about the AI voice databases sounding so close to the VAs[1], but nobody can afford the risk to publish another version so similar to VA. BUT, the success of Mai may show another road, that is to clone VA’s as-is. As for me, if(and only if) the high part of Chiyu performs well, both way is acceptable.

[1] Some people treat Chiyu as VA’s “daughter”, listen to VA version & Chiyu version(p1 with bgm p2 without bgm) of the same song, and you can have you own opinion about this statement.
