I understand all of this, but the point still stands. If you are going to teach an on’yomi reading with the Kanji, then it’s easier to learn that with audio. That has nothing to do with the Japanese language as a whole, the difference between on’yomi and kun’yomi readings, what a Kanji actually is, or even a person’s learning style. It’s just about how people learn sounds, which is what a reading is.
As long as on’yomi readings (or any reading) are taught with new Kanji and quizzed in such a way that you must learn the reading to progress, including a sound will be better for that learning progression. That’s the learning progression the creators of this software(which I really like, for the record) chose to use, which apparently the other people in this thread disagree with. To say we should learn a reading with the Kanji but contend an accompanying sound file is unimportant or doesn’t belong is nonsensical. Pick a lane.
They should mention that in the intro tour. Plugging my headphones in now. Thank you.
