How to Use the Biggest Mismatch Region

The highlighted mismatch region shows the part of the sentence where your pitch shape differed most from the reference. It is the app’s way of saying: “Start here.”

What it means

SpeakTune aligns your recording with the reference, then compares the pitch shape over time. The mismatch region is the section with the largest pitch difference.

For Mandarin and Cantonese speakers, this often appears near a focus word, a final word, or a place where English needs a smoother rise or fall than your first language naturally uses.

What it does not mean

• It does not mean every other part was perfect.
• It does not mean your voice should be the same pitch as the reference.
• It does not mean you should copy the speaker’s identity or accent exactly.
• It does not mean you need to fix everything at once.

How to fix a mismatch

1. Listen to the reference and watch only the highlighted area.
2. Hum that small section without words.
3. Say only that phrase slowly.
4. Put the phrase back into the full sentence.
5. Record again and see whether the highlight gets smaller or moves.

If the mismatch is near the end

Practice the final word alone. Let it fall down clearly if the sentence is a statement. Then add the previous word, then the full sentence.

If the mismatch is near the middle

Look for the focus word. You may need to make that word longer, clearer, or more pitch-prominent, while keeping the surrounding words lighter.

If the mismatch appears everywhere

Do not try to fix the whole graph. Start by humming the sentence melody. Then record one slow version before returning to natural speed.
