Phonetics

• b (unaspirated): soft release with no extra breath, e.g. bà (把)
• p (aspirated): forceful release with noticeable breath, e.g. pà (怕)
• Tip: hold your hand in front of your mouth; p pushes air at your hand, b does not

Tone marks (1st–4th) change the pitch contour, not the base sound. mā (妈), má (麻), mǎ (马), mà (骂) share the same syllable, only the pitch differs. Wrong tone = wrong word.

• -er (e.g. ér 儿, èr 二): a standalone retroflex r-colored final
• As the suffix -r (erhua), it does not form its own syllable but merges with and r-colors the previous final, e.g. zhèr (这儿), wánr (玩儿)

r (rù 入) uses a curled-up tongue (retroflex), unlike English or Vietnamese 'r'. It sounds somewhat like z but with more tongue curl. Tip: say 'j' quietly and you get r.

• h (velar): a breathy fricative from the back of the mouth, e.g. hǎo (好)
• x (palatal): lighter, the tongue front near the hard palate, like 'hs', e.g. xiǎo (小)
• x is much lighter and higher than h

• -ong: more closed mouth, e.g. gōng (功)
• -ang: more open mouth, e.g. gāng (刚)
• -eng: in between, e.g. gēng (更)

Remember: closed → mid → open as ong → eng → ang

q always sounds like 'ch' in English "cheese", never like 'k'. Example: qù (去) sounds like "chjù". Whenever you see q, think 'ch' immediately.

• sh (retroflex): shān (山)
• s (dental): sān (三)
• x (palatal, like 'hs'): xiān (先)

Each uses a different part of the mouth; careful listening is key.

• -ing (e.g. píng 平): ends with the velar nasal ng (back of the tongue at the soft palate)
• -in (e.g. pīn 拼): ends with the alveolar nasal n (tongue tip at the ridge behind the teeth)
• Feel where the closure happens: back of the mouth vs. front

• ch (retroflex): tongue curls up, e.g. chī (吃)
• c (dental): pronounced at the front teeth, e.g. cí (词)
• Tip: ch sounds 'deeper', c sounds 'flatter'

After n, l, j, q, x, the letter ü is written as u in pinyin for simplicity. Example: nü (女) appears as 'nu' but is pronounced with the ü sound (rounded u).

• zh (retroflex): tongue curls back, e.g. zhù (住)
• z (dental): tongue tip behind the upper teeth, e.g. zài (在)
• j (palatal): tongue front against the hard palate, e.g. jī (鸡)

In words like 中 (zhōng), the final is /ong/ with a back nasal. Your tongue drops to nearly create /u/, but you add the /ng/ nasal resonance, not a front /on/ sound.

c (次 cì) is a dental/alveolar affricate, the aspirated partner of z. k (可 kě) is velar (back of the mouth). They are made in completely different positions.

ao (as in 好 hǎo) goes from wide open /a/ to /o/. ou (as in 后 hòu) goes from /o/ to /u/. Track the vowel sequence, and they'll stay distinct.

l (as in 拉 lā) keeps your tongue flat; r (as in 然 rán) curves your tongue back immediately. This is why le (了) and re (热) sound completely different.

n (as in 你 nǐ) is made with your tongue touching the alveolar ridge. ng (as in 唱 chàng) is made with the back of your tongue in your throat. Different places, not different intensities.

In le (了) and me (么), /e/ is more open. In bei (背) or mei (美), it's closer to a front vowel. The rule: listen to native speakers and adjust your mouth opening accordingly.

You'll never see ja, qa, or xa in Mandarin. These palatal sounds only work with high front vowels: ji (基 jī), qu (去 qù), xi (西 xī).

r (as in 日 rì) has your tongue in a retroflex position, curled back like zh/ch/sh, not touching the alveolar ridge. This is why it sounds distinct from the z/c/s series.

The primary difference is tongue position: sh (书 shū) and s (四 sì) are both unaspirated, but sh is retroflex and s is dental. Likewise zh is retroflex and z is dental.

ch (吃 chī) is a retroflex affricate (tongue curled back); q (起 qǐ) is a palatal affricate (tongue front to the hard palate). Both are aspirated. The main difference is the place of articulation, not the breath.

When you see xu, ju, or qu in pinyin, the 'u' always represents /ü/ (the rounded front vowel). There's no need for an umlaut, these three initials always trigger the rounded sound.

zh (as in 中 zhōng) is retroflex: the tongue curls back. z (as in 自 zì) is dental: the tongue tip touches just behind the upper teeth. Feel the difference in tongue position.

These initials have strict restrictions: b, p, m never pair with ü or er, and f never pairs with i or ü. But bi, pi, mi and be-class finals do exist (比 bǐ, 皮 pí, 米 mǐ). Learn which combinations are valid.

These initials have strict co-occurrence restrictions. b/p/m appear only with a, o, u or -ng, -ang finals. There is no Mandarin syllable 'be', 'pi', or 'mü'. Memorize the valid combinations.

ou glides from o to u (like 'oh'). uo glides from u to o. Examples: 后 (hòu, 'hoe') vs. 多 (duō, 'dwor'). The direction of the glide matters.

ei starts with e and glides to i (like English 'ay'). ie starts with i and glides to e (like 'yeh'). Examples: 黑 (hēi) vs. 提 (tí), 结 (jiē) vs. 就 (jiù). The direction is reversed.

ia = i + a glided together. ua = u + a. uo = u + o. Pronounce each as a single smooth unit, not separate letters. Examples: 家 (jiā), 瓜 (guā), 多 (duō).

h is a voiceless fricative from the back of the mouth/throat. f is a labiodental fricative (lower lip against upper teeth). Examples: 何 (hé) vs. 服 (fú). h sounds breathy and light, f sounds sharp and buzzy.
