Popular seiyuu: 130 yen per word
Average seiyuu: 100 yen per word (standard price in the industry)
Leave it to them to decide: 90 yen per word (when you ask them for cheap usable people)
Overworked seiyuu: +30 yen
Negotiating with seiyuu that won’t do rape: +20~50 yen
Take everything from the same agency: -10~20 yen
Even when a seiyuu has 5000 words, the price per word will not go down in most cases.
Also if it’s not at least 100 words, they might not accept the job due to stuff like transportation fees and such. So in cases where it’s in the vicinity of 100 words, the company will ask them if it’s possible to do it for something like 20,000 yen instead of going on a per word basis.
Studio costs:
Budget home studio: 3000~5000 yen
Average minor studio: 6000~8000 yen
Average major studio: 9000~12000 yen
Sound editing costs:
Do in-house: 0 yen (not recommended)
Budget sound editing: 30~50 yen (they won’t normalize the voices for you so it’s not recommended, games where the voices are soft during normal scenes and loud during H scenes are done at this price)
Average sound editing: 60~80 yen
Sound editing by somewhere famous: 90~120 yen
Censorship of obscene words
Done in-house: 0 yen (best to do in-house)
Done somewhere else: approx. 50 yen (might be cheaper if asked to do with sound editing)
If you get somewhere that has a studio to handle all the audio related stuff there will be some discounts.
Censorship of obscene words refers to “chinko” and “manko”. Censorship is required when there are seiyuu in the cast that won’t allow these words to be in the game, in such cases the company may censor all instances of these words in the game to standardize
One person says that with their company, it costs at least 1,500,00 yen to 1,600,000 yen for 10,000 words with all costs involved. And that is when they leave it to the agency to pick seiyuu for them. If they pick the seiyuu themselves it easily costs +500,000 yen
Depending on the agency, there are also seiyuu that will take a % of the original costs as secondary use license royalties if the company decides to release a downloadable version, a budget version, PG version, or console ports etc
When a console port or an anime is made, these costs are usually paid by the company in charge of the port, if it’s done in-house then royalties have to be paid together with the additional voices
Ero anime only pays approximately 10,000 yen per episode and takes a day, so when an eroge becomes an ero anime, there are a lot of seiyuu that will refuse to do voices for the ero anime, which is why the ero anime versions usually have a different voice cast
Seiyuu voice recording costs has apparently increased dramatically in recent years, agencies did not charge on a per word basis or ask for secondary use license royalties 5 years ago. Comments from some say it is now about 150% to 300% as compared to before.
