Most Japanese learners never hear their pitch mistakes. JPitch makes them visible — with real-time F0 analysis, not guesswork.
Speak any Japanese word or sentence. JPitch extracts your F0 pitch contour and grades it against the native pattern — no AI, no guessing.
Your pitch contour is overlaid against the correct NHK-style pattern from UniDic's 750,000-entry dictionary.
Per-mora grading tells you exactly which morae were wrong, by how much, and tracks your improvement over time.
In Japanese, pitch accent isn't just about sounding natural. It determines meaning.
Say はし (hashi) with the wrong pitch and you could be asking for a bridge when you want chopsticks.
Unlike English stress, Japanese pitch is binary: each mora is either High or Low. Once it drops, it never rises again in the same phrase.
Every word belongs to one of four accent classes: Heiban (flat), Atamadaka (head-high), Nakadaka (mid-high), or Odaka (tail-high).
Dictionary entries list an accent number (0, 1, 2, 3…) that tells you exactly where the pitch drops. Learn the number, nail the word.
Enter a word like 橋 or a full sentence. JPitch segments it and looks up every pitch pattern.
Hit record and say it naturally. Your audio is processed on our servers and never stored.
A side-by-side pitch contour shows you where you rose or fell incorrectly, mora by mora.
Just starting out? Build correct pitch habits from day one instead of unlearning bad ones later.
Tip: Start with N5 words in the word list — short, common, and immediately useful.
Plateau-ing on fluency? Pitch accent is often the missing piece that separates 'studied' from 'natural'.
Tip: Use the minimal pairs filter to drill words you know but might be mispronouncing.
Aiming for near-native? JPitch gives you objective data on exactly which morae are still off.
Tip: Try sentences, not just words — pitch accent in context is where true fluency lives.
Everything you want to know about the pitch accent trainer.
JPitch uses real-time F0 (fundamental frequency) extraction to measure the pitch contour of your voice as you speak. It segments your audio into individual morae — the basic sound units of Japanese — and compares each mora's pitch (High or Low) against the correct pattern stored in the UniDic dictionary. The result is a mora-by-mora accuracy score based on pure tonal analysis, with no AI or machine learning involved. Your recording is processed on our servers and immediately discarded.
The practice word list contains over 160,000 Japanese words covering JLPT vocabulary from N5 through N1, organized by level, frequency rank, and part of speech. For sentence and free-text input, JPitch draws on a backend dictionary of over 700,000 entries to look up pitch patterns for virtually any word you type. You can also practice number compounds (１０月, ２０日, etc.), search by kanji, kana, or romaji, and save favorites for focused review.
Every time you record a word, JPitch logs your score and updates your mastery level for that word: learning (below 60%), familiar (60–84%), or mastered (85%+). Your best score and most recent score are both tracked separately. A daily practice streak counts consecutive days you've practiced, and the streak resets automatically if you skip a day. The dashboard shows your daily goal progress, average score, total words practiced, and longest streak.
A dictionary tells you what the correct pitch pattern is — it can't tell you whether you're actually producing it. JPitch closes that loop. You see the target pattern, record yourself, and immediately see your pitch contour overlaid against the native pattern. The visual comparison makes it obvious which morae are too high, too low, or dropped at the wrong point. Over time, your scores track whether you're improving — something a static dictionary entry can never do.
JPitch works entirely in the browser — no app download required. It runs on any modern browser that supports the Web Audio API and microphone access, including Safari on iOS, Chrome on Android, and all desktop browsers. On mobile, make sure to allow microphone permissions when prompted. The interface is fully responsive and optimized for smaller screens.
Yes, JPitch is free to use with a free account — no credit card required. Your voice recordings are sent to our servers solely for pitch analysis, are never stored, and are never used to train AI models. The analysis is performed using deterministic signal processing (F0 extraction), not a speech model. We do not sell or share your data. See the Privacy Policy for full details.
