As evidenced by a couple recent posts, many Japanese learners make it surprisingly far into their studies prior to the shocking discovery that pitch accent exists in Japanese, and that understanding how to acquire it correctly it is essential for speaking Japanese without an obvious accent.
Whether or not to dive into this subject (and when) is apparently slightly controversial, but for those who have decided to take the plunge, here’s a place to share resources, strategies, and questions. I’ll keep a running list of all the resources so please kindly share what you know of!
We do have a couple users with deep knowledge of the subject like @jjatria, and I’m fairly sure Dogen lurks in these forums…
References with pitch accent info
Apple J-2-J - if you are on a mac, open up the dictionary app and turn on the Japanese to Japanese dictionary and you’ll find one of the clearest references for pitch-accent information available… the information comes from the 大辞林, and you can see the charts here.
Forvo – get recordings of native speakers pronouncing almost any word, and request items they don’t have (I’ve used the request feature and got a pronunciation within a day)
