Use utilities from Kotu on your Anki cards. Kotu uses a combination of UniDic for MeCab and different accent dictionaries and custom parsing strategies. Works on mobile and desktop. Most utilities require internet.
Setup: Use the “Tools” → “Add Kotu Utilities to Note Type” menu to have the script added to a note type.
Collection Includes:
Auto Pitch (Requires Internet) Uses Kotu to parse the sentence and add underlines to the text corresponding to the pitch accent pattern. [pitch: そしてその隣にあるのが僕の部屋だ。]
Auto Visual Pitch (Requires Internet) [vpitch: そしてその隣にあるのが僕の部屋だ。] Uses Kotu to parse the sentence and add overlines / drops to the text corresponding to the contour of the phrase’s pitch taking into account any sentence level changes. Not 100% perfect but on its way there.
Auto Frequency (Requires Internet) Uses Kotu to parse the sentence and add underlines to the text corresponding to the frequency of the word. [frequency: そしてその隣にあるのが僕の部屋だ。]
Manual Pitch Parses the provided text and visually displays the pitch accent with overlines / drops. ＼ should be placed after the accent drop. ・ should be placed between phrases. ｀ should be placed before moras with silenced vowels. [mpitch: そ｀して・その・となりに・あ＼るのが・ぼ＼くの・へや＼だ。]

awesome, insanely useful and underrated. It’s a shame it was never updated.
I made a version of the setup script that’s easier to use. now you don’t have to wrap [pitch:], [vpitch:], [mpitch:], or [frequency:] around each paragraph of the field for each card manually. You just put it around the field in the card template code editor, like this: [vpitch: {{Sentence}}]
let’s suppose the field {{Sentence}} has: 僕が悪だと？ 僕は正義だ！ it automatically turns into: ボクガワルダト？ ボクワセーギダ！ it applies the formatting

Great! Very useful for learning correct stress accent, automatic features do not use much data so happy to use them and MUCH less effort than manual imnput. Important: no formatting whatsoever is best as input.

Thx so much, it’s a must have! I’m just hoping that the day it goes down, I won’t need it anymore

Hi, can anyone explain how to use the utilities? I’ve added the script to my card.

The fix to make vpitch work.
- Get an editor with the ability to do regex find and replace. Notepad++ will do.
- Copy the generated JS text from the card template to the editor (starts with <style>)
- Open Find and Replace window, enable regex, fill in the following fields: Find: replaceAll(”(.*?)” Replace: replace(/$1/g
- Press Replace All, copy the changed text back into the card template.
- Restart Anki.
The plugin doesn’t always show the whole sentence when using [pitch]. An example:

Can you add a preference to turn off furigana?

Doesn’t work if you have any formatting in the field you want to use it on, other than that good. I hope that that will be fixed though.

Great addon!
Everything works fine except for the “vpitch” function, I can’t get it to work on Mac OS (it works fine on Android).
UPDATE
It seems that Anki on MacOS doesn’t support the replaceAll() function. I replaced that to a global replace() function and now it works fine.
