The question nobody answers: how much Japanese does this thing actually need?
If you have ever bought a Japanese voice work on the strength of the cover art and then spent forty minutes listening to a woman say things you could not follow, this page is for you. There is a way to predict that before you pay, and almost nobody publishes it.
Here is the problem in one line. Search "DLsite english" and you will find people who will tell you how to pay, how points work, what the tags mean. Useful stuff. But the thing that actually decides whether you enjoy a work — whether the Japanese matters — is not on any product page, not in any database, and not in the auto-translated title.
So that is the one number I put on everything here, and it is measured rather than felt. The method and the exact cutoffs are published, including the one I had to move after it nearly mislabelled a work as the opposite of what it was.
Three levels, and what they really mean
Barely any. Moans, breathing, wet sounds, the binaural placement of a voice moving around your head. There is technically dialogue, but it is texture. You lose flavour by not understanding it; you do not lose the thing you bought it for.
Some. There is a situation, and the situation is half the appeal. A nurse, an interrogation, a shop with a menu of services. If you know the setup going in, you are fine. If you do not, you will spend the first ten minutes confused and then it clicks.
A lot. Dialogue is the work. Countdowns, instructions, teasing that lands on specific words, a story with a turn in it. Without Japanese you are listening to a pleasant voice make sounds. Some people genuinely enjoy that. Most people who paid ¥1,320 for it do not.
That third category is where the money gets wasted, and it is much bigger than English buyers assume. Japanese doujin audio is not mostly ASMR. A huge slice of it is scripted.
Why you cannot just look this up
Two reasons, and the second one is the interesting one.
The first is boring: the tags do not encode it. A work tagged 癒し (iyashi, "soothing") can be forty minutes of monologue.
The second is that this cannot be scraped. There is no field for it. You cannot infer it from the description, because Japanese product descriptions are written to sell, not to warn. The only way to know is for a person to open the free sample, listen, and make a call. That is slow, it does not scale, and it is exactly why nobody has done it.
It is also why I am not going to pretend I have done it when I have not. Where a work here says not rated yet, it means I have not sat with the sample long enough to be sure. I would rather leave a hole than fill it with a guess, because a guess is worth nothing and this rating is the only thing this site really sells.
What to do with the free sample yourself
Most works on DLsite have a free sample, and most English buyers skip it because the product page is in Japanese and the play button is not obvious. Do not skip it.
There are actually two different things a circle can offer you for free, and they are easy to confuse. One is a streaming sample you play in the page. The other is a trial download, a zip from the shop that you unpack yourself. Plenty of works have one and not the other, and a work with no player on the page may still have a trial sitting further down.
And some have neither. I found a work with over eighteen thousand sales that offers nothing free at all, which means buying it unheard. That should push the price you are willing to pay down rather than up.
When you play it, you are not judging whether you like the voice. You are judging one thing: is she talking, or is she making sounds? Listen for the ratio. If the sample is thirty seconds of speech before anything else happens, that is your answer about the other fifty minutes.
The other tell is pacing. Scripted works have the rhythm of someone reading. Full stops, breaths in the same places, a turn at the end of each sentence. Sound-led works do not have that shape at all. You can hear the difference without a word of Japanese, which is a slightly funny thing to be able to say.
One honest limitation
I am one person and there are tens of thousands of these. This site will never cover the catalogue. What it can do is cover a narrow slice properly. Currently that is the femdom and male-receiving end of it, because that is where I can tell a good one from a lazy one at speed.
If you want the whole catalogue translated, j-asmr-wiki has done an enormous amount of work on exactly that and you should use it. If you want to know how to pay from outside Japan, Doujin Buyer Guide covers it better than I would. I am not going to write worse versions of those.
I am doing the part they are not: telling you which ones are worth your forty minutes when you cannot read a word.
Start with one work. Find its sample, count how long she talks before anything else happens, and decide from that. If there is no sample, treat the work as a gamble and price it accordingly.
