Seven Core Mandarin Pronunciation and Spelling Rules

The video reviews seven core Mandarin pronunciation and spelling rules. The presenter explains that these rules help make pronunciation smoother, distinguish similar sounds, and clarify how pinyin spelling relates to pronunciation.

1. How to Pronounce e

The sound of e depends on the syllable:

• In syllables such as ge, ke, and he, it is pronounced roughly like [ɤ]—similar to “uh,” but made farther back in the mouth.
• In combinations such as ie and üe, it is closer to [ɛ], like “eh.”

The video uses a mnemonic to help learners remember the difference, but it is not reliably preserved in the auto-generated subtitles.

2. i, u, ü at the Beginning of a Syllable or Standing Alone

When these sounds begin a syllable or form a syllable by themselves, their pinyin spelling changes:

• i → yi
• u → wu
• ü → yu

The dots over ü may be omitted in the spelling, but the sound still uses rounded lips. Similar spelling changes apply when these vowels combine with other finals, such as ia → ya and ua → wa.

3. Two Third Tones Together

When one third-tone syllable is followed by another third-tone syllable, the first is generally pronounced with a rising, second-tone-like contour. The written tone marks usually remain unchanged; the change occurs in speech.

For longer sequences of third tones, divide the phrase into meaningful groups. Tone changes depend on phrasing, so learners should not mechanically change every syllable.

4. Tone Change for 不 (bù)

不 is normally pronounced bù. Before a fourth-tone syllable, it changes to bú. Before other tones, it generally remains bù.

The presenter explains that this change helps the phrase sound more natural.

5. Tone Changes for 一 (yī)

In connected speech, 一 changes tone according to the tone that follows:

• Before a fourth tone, it is usually pronounced yí.
• Before a first, second, or third tone, it is usually pronounced yì.
• It generally remains yī when spoken alone, at the end of a phrase, or in ordinal use, as in “first.”

6. The Special Pronunciation of i After Seven Initials

After z, c, s, zh, ch, sh, and r, the written i is not pronounced like the usual “ee” vowel. It is a special syllabic vowel sound, often described in teaching materials as an “ɿ/ʅ”-type sound.

The spelling still uses i; learners need to learn its different pronunciation through listening and practice.

7. j, q, x Followed by ü

After j, q, and x, the dots over ü are omitted in pinyin. Syllables written with u after these initials may therefore use the ü sound, as in ju, qu, and xu.

Keep the lips rounded when saying these syllables; do not pronounce them with the ordinary u sound.

Practice Advice

• Review the rules and practise reading examples aloud.
• Record yourself to check your pronunciation.
• The presenter says learners may send a recording through Facebook for feedback.
