Pinyin final: "ei3"

Mouth Mechanics (Step-by-step)

1. Start relaxed and neutral: Jaw slightly open; lips relaxed (not rounded).
2. Begin with an “eh” mouth shape:
   • Tongue is forward and fairly flat, with the middle of the tongue gently lifted.
   • Lips are spread/neutral, like a small, polite smile (not wide).
3. Glide into a light “ee” finish:
   • Without changing the jaw much, let the tongue slide a bit higher and more forward toward an “ee” position.
   • Keep the “ee” part brief; it’s a glide, not a full second vowel.
4. Add Tone 3 (the “dip”):
   • Start mid, sink down, then come back up.
   • In normal conversation, the “dip” is often small unless the syllable is stressed or said alone.

Key feeling: One smooth vowel that moves from “eh” → “ee”, not two separate vowels.

English Approximation (2–3 anchors)

These are near matches; the goal is to copy the vowel glide while avoiding extra English habits.

• “say” — use the vowel in sAY (the “ay” part).
  Match: the main vowel glide.
  Adjust: make it shorter and cleaner, with no trailing “y” sound lingering at the end.

• “they” — use the vowel in thEY.
  Match: the same ay-like quality.
  Adjust: don’t let it turn into a long, tense English diphthong; keep it compact.

• “eight” — use the vowel in EIGHt.
  Match: the ay glide.
  Adjust: ignore the final consonant; focus only on the vowel, and keep it tight and controlled.

If your English “ay” is very strong (very “ee”-heavy at the end), aim for more “eh” at the start and a lighter finish.

Common Mistakes (English speakers)

• Making it “eh + ee” as two clear vowels: It should be one syllable, one smooth glide, not “eh-EE.”
• Adding an extra “y” sound at the end: English often ends “ay” with a noticeable y-like tail. In Mandarin, the finish is lighter and should stop cleanly.
• Using the wrong starting vowel: Don’t start from “eye / aɪ” (like “my”). This final starts closer to “eh”, not “ah.”
• Forgetting Tone 3 shape: Tone 3 is not flat; it has a dip. If you say a steady “ay,” it won’t sound right.

Practice Pairs (Pinyin ↔ English approximation)

Use the English word only as a sound hint—the Mandarin result should be shorter, cleaner, and tonal.

Comparisons & Caveats (similar Pinyin finals)

A) ei vs ai

• ei (as in bei3, mei3) is like “ay”: it starts closer to “eh.”
• ai is like “eye”: it starts more open, closer to “ah.”

Practical check: if your jaw drops a lot at the start, you’re drifting toward ai, not ei.

B) ei vs en / eng

• ei ends with a high front glide (a light “ee”-like finish).
• en/eng end with nasal resonance.

If you feel vibration in your nose or a nasal “n/ng” closure, you’re not doing ei.

C) ei alone vs -uei after certain initials (spelled “ui” in Pinyin)

Syllables like dui3, gui3, hui3, zui3, cui3, sui3, tui3, shui3, rui3 contain a w + ei sequence (often written ui, but pronounced like (w)ei).
- Keep the w quick and light (rounded lips briefly), then go straight into the ei glide.
- Don’t turn dui3 into “doo-ee” or “dway” with an exaggerated English-style glide. It should feel like one tight syllable.

D) Tone reminder for ei3

Tone 3 is mid → low → rise. When said clearly or alone, you’ll hear the full dip; in fast speech, it may sound mostly low unless it’s emphasized.
