Written one way, read another

The four sets

Click a cell: A = written form, B = actual reading.

Minimal pairs in sentences

Two sentences side by side, differing by one sound in the same slot. Tap a card to hear the whole line, tap the highlighted part to hear just that.

1. Aみずをwo read as oみずを、のみます。☆

   Bおちゃoおちゃ、を、のみます。☆
2. Aがっこうへhe read as eがっこうへ、いきます。☆

   Bえきeえき、へ、いきます。☆
3. Aはなぢdi = jiはなぢ、が、でます。☆

   Bじしょjiじしょ、を、みます。☆
4. Aみかづきdu = zuみかづき、が、きれいです。☆

   Bすずめzuすずめ、が、います。☆

Homophones and correlation

Near 1 = the waveforms nearly coincide; clearly lower = different sound. The へ row is the control: read alone it is he, so it must be low — which shows the measure can tell same from different.

How to practise

• を only appears as a particle and is always o, never wo.
• へ as a particle is e (学校へ行く); inside a word it is he (部屋 heya).
• ぢ / づ survive mostly in rendaku and nasalised contexts (はなぢ).

Where these numbers come from

Both kana synthesised in one voice, spans aligned at onset, zero-lag Pearson correlation. A correlation near 1.00 could also mean the same file twice, so the page carries a control pair that should differ (を vs え).
