BPMF & DTNL: Master the First Chinese Pinyin Initials
Learning Chinese pinyin? BPMF (b, p, m, f) and DTNL (d, t, n, l) are the first two groups of initials you'll encounter — and the foundation for every pinyin syllable you'll ever type. This guide breaks down each sound with pronunciation tips, audio examples, and common words so you can master them with confidence.
What Are BPMF and DTNL?
In the Chinese pinyin system, the 21 initials (声母, shēngmǔ) are the consonant sounds that begin a syllable. They are traditionally taught in groups, and the first two groups are:
- BPMF: b, p, m, f — the lip sounds (唇音, chúnyīn)
- DTNL: d, t, n, l — the tongue-tip sounds (舌尖音, shéjiānyīn)
These 8 initials are the easiest for English speakers to learn because they have close equivalents in English. That's why every Chinese phonics textbook starts here.
In Taiwan, "BPMF" (ㄅㄆㄇㄈ) also refers to Zhuyin/Bopomofo, an alternative phonetic system. In this guide, we focus on the pinyin romanization used in mainland China and most learning apps.
The BPMF Group: Lip Sounds
The first four initials are all produced with the lips. Let's break them down one by one.
B — Like English "b" but unaspirated
The pinyin b sounds similar to the English "b" in "bat," but without the puff of air. Place your hand in front of your mouth — you should feel almost no air when saying the Chinese "b."
Listen to words starting with B:
P — Like English "p" with a strong puff of air
The pinyin p is aspirated — you should feel a clear burst of air against your hand. This aspiration is the key difference between b and p in Chinese.
Listen to words starting with P:
M — Same as English "m"
The pinyin m is pronounced exactly like the English "m." Your lips close together and the sound comes through your nose.
Listen to words starting with M:
F — Same as English "f"
The pinyin f is identical to the English "f." Upper teeth touch the lower lip and air flows through.
Listen to words starting with F:
The DTNL Group: Tongue-Tip Sounds
The next four initials are produced with the tip of the tongue touching the upper teeth ridge (alveolar ridge).
D — Like English "d" but unaspirated
Similar to English "d" in "dog," but without the puff of air. Keep it crisp and short.
Listen to words starting with D:
T — Like English "t" with a strong puff of air
The pinyin t is the aspirated counterpart of d. Just like the b/p pair, the difference is aspiration, not voicing.
Listen to words starting with T:
N — Same as English "n"
The pinyin n sounds just like the English "n." The tongue tip touches the upper teeth ridge and the sound comes through the nose.
Listen to words starting with N:
L — Same as English "l"
The pinyin l is pronounced like the English "l." The tongue tip touches the upper teeth ridge and air flows around the sides.
Listen to words starting with L:
Key Differences: Aspirated vs. Unaspirated
The most important concept in BPMF and DTNL is aspiration — the puff of air that distinguishes certain pairs of initials.
| Unaspirated (no puff) | Aspirated (strong puff) | Test |
|---|---|---|
| b (爸 bà) | p (怕 pà) | Hold a tissue in front of your mouth — it should move only for p |
| d (大 dà) | t (他 tā) | Same tissue test — it should move only for t |
English speakers often confuse aspiration with voicing. In English, "b" is voiced and "p" is voiceless. In Chinese, both b and p are voiceless — the only difference is the puff of air. This is why Chinese "b" may sound like something between English "b" and "p."
The Tissue Test
Try this simple exercise:
- Hold a thin tissue or piece of paper 5 cm from your mouth
- Say bā (八) — the tissue should barely move
- Say pà (怕) — the tissue should flutter clearly
- Repeat with dà (大) and tā (他)
If the tissue moves the same amount for both, you need to practice reducing aspiration on b and d.
Common Words Using BPMF & DTNL
Here are high-frequency words organized by initial — perfect for typing practice:
BPMF Words
| Initial | Word | Pinyin | Meaning |
|---|---|---|---|
| B | 不好 | bù hǎo | not good |
| B | 北京 | Běijīng | Beijing |
| P | 朋友 | péngyou | friend |
| P | 漂亮 | piàoliang | beautiful |
| M | 没有 | méiyǒu | don't have |
| M | 明天 | míngtiān | tomorrow |
| F | 非常 | fēicháng | very |
| F | 方便 | fāngbiàn | convenient |
DTNL Words
| Initial | Word | Pinyin | Meaning |
|---|---|---|---|
| D | 地方 | dìfang | place |
| D | 电话 | diànhuà | phone |
| T | 同学 | tóngxué | classmate |
| T | 特别 | tèbié | especially |
| N | 那个 | nàge | that one |
| N | 能力 | nénglì | ability |
| L | 老师 | lǎoshī | teacher |
| L | 旅行 | lǚxíng | travel |
Practice Tips for Mastering BPMF & DTNL
1. Practice in Minimal Pairs
Train your ear and mouth by contrasting similar sounds:
- bā (八, eight) vs. pā (趴, to lie prone)
- dā (搭, to build) vs. tā (他, he)
- nà (那, that) vs. là (辣, spicy)
2. Use Typing Practice
Typing pinyin reinforces the connection between sounds and spelling. When you type "ba" and select 八, your brain builds a three-way link: sound → pinyin → character.
3. Record and Compare
Record yourself saying each initial and compare with native audio. Pay special attention to the aspiration pairs (b/p and d/t).
4. Practice All Four Tones
For each initial, practice combining it with all four tones:
- bā, bá, bǎ, bà
- pā, pá, pǎ, pà
- dā, dá, dǎ, dà
- tā, tá, tǎ, tà

What Comes After BPMF & DTNL?
Once you've mastered these 8 initials, you're ready for the next groups:
- G, K, H — velar sounds (tongue back)
- J, Q, X — palatal sounds (unique to Chinese)
- ZH, CH, SH, R — retroflex sounds (the hardest for English speakers)
- Z, C, S — dental sibilants
Each group builds on the articulatory skills you develop with BPMF and DTNL, so take time to get these right first.
Frequently Asked Questions
Is BPMF the same as Bopomofo?
"BPMF" can refer to two things: (1) the first four pinyin initials (b, p, m, f), and (2) Bopomofo (ㄅㄆㄇㄈ), the phonetic system used in Taiwan. Both represent the same sounds, but use different symbols. This guide covers the pinyin version.
Why do Chinese b and p sound different from English?
In English, b is voiced (vocal cords vibrate) and p is voiceless. In Chinese, both are voiceless — the difference is aspiration (a puff of air). Chinese b sounds "softer" than English b to many learners.
How long does it take to master BPMF and DTNL?
Most learners can produce these sounds accurately within 1–2 weeks of daily practice. Since they're similar to English sounds, they're the fastest initials to learn.
