Japanese audio flashcards: drill vocabulary entirely by ear.

Audio flashcards are spaced-repetition flashcards you review without a screen: the app speaks the prompt, you answer out loud, and it grades you and schedules the next review. That’s different from vocab playlists or podcasts, which never test you. Kotoba is a free web app built around exactly this loop for Japanese — JLPT N5–N3, native audio, hands-free from the first word to the last.

What are audio flashcards?

A normal flashcard asks your eyes a question; an audio flashcard asks your ears. The whole review loop happens in sound: a spoken prompt (“apple… in Japanese?”), a pause while you recall and say the answer — りんご — then confirmation and an example sentence. Grading and scheduling work like any SRS deck: words you know retreat into the future, words you fumble come back soon. The point is that active recall survives — you’re still being tested on every card — while your eyes and hands stay free for the road, the dishes, or the dog.

“Can’t I just listen to a vocab playlist?”

This is what most people find first: JLPT word-list albums on Spotify and YouTube, exported Anki deck audio, “learn Japanese while you sleep” compilations. They all share the same problem — they never ask you anything. Every word plays in a fixed order on a fixed schedule whether you’ve known it for months or never learned it. Recognition (“oh, I’ve heard that”) builds quickly; recall (producing the word yourself) doesn’t. Decades of testing-effect research say the quiz is the learning. A playlist is a radio show about your flashcards, not flashcards.

The options, honestly compared

Anki with audio fields is excellent at home — but it can’t run screen-free (we wrote up why in Anki while driving? Here’s the audio-only alternative). Audio courses like Pimsleur are genuinely hands-free but play the same fixed lessons to everyone, with no memory of which words you keep missing.

Disclosure: this page is by the developer of Kotoba — the app below is mine.

Kotoba is the audio-flashcard loop, built as its own product rather than bolted onto a visual app. Tap Start once and the session runs itself: new words get a slow spoken breakdown and a natural example sentence; review words get quizzed right before you’d forget them (FSRS scheduling — the same modern algorithm Anki offers); your spoken answers are graded by cloud speech recognition, and “repeat”, “skip”, and “pause” are voice commands. As words mature, the difficulty climbs: eventually you hear the example sentence with a beep where the word belongs and supply it yourself.
