How this works
- Use the confirmed pinyin readings to derive numbered tones and stable visual contours.
- Check repeated tones, neighboring initials and finals, and likely reading friction as separate observations.
- Show level and oblique tones (Ping and Ze) as a traditional lens, not as a scientific quality score.
Common questions
About this tool
What are Ping and Ze?
Ping and Ze are traditional level and oblique tone groupings. They are shown as a cultural lens alongside the numbered Mandarin tones.
Is one tone pattern always better?
No. The tool flags repetition and transitions for review, but clarity also depends on pronunciation, dialect, context, and personal preference.
