In Japanese it is quite important to know the pitch-accent of words if you want to strive for native pronunciation. I would like to see an option to be also be prompted for the pitch accent of words.
I do not know a good source for the pitch accents of words. but the dictionary wadoku.de includes them and there is a free tool from the University of Tokyo which tries to generate correct pitch accent for japanese sentences (not always correct).
I agree 100% and this is something we’ve discussed as a team often. A comprehensive, accurate, (and preferably importable) source is the one thing that’s prevented us from adding it in just yet. This is definitely something that would be an incredible improvement to the Japanese side of things.
from what i can tell, wadoku is a dictionary and has the associated accuracy. However commercial access to their data is not for free and you would need to contact them to find an agreement that is agreeable with both parties.
Generally they require companies integrating their dictionary into commercial software to give them a share of the total income, but I assume this is more for using all of the dictionaries content and you could get something better as you only want the pitch-accent information.
anyway you could try contacting them, i think the following page contains the best current email: https://wadoku-ev.de/kontakt/
Alternatively, I know that on apple devices the standard installed dictionary comes with pitch accent information. you could try contacting the publisher of that as well
I really appreachiate that you are expanding japanese content as well.
However, I really cannot wait for you guys to add pitch accent support.
i speak japanese fluently but because no one every thinks about pitch accent i never learned it properly and Dogen videos are not enough really. i feel so embarrased about my wrong pitch accent all the time
