The initial: b
[p]
- What the mouth does
- Lips together, then released with no puff of air. The vocal cords stay quiet until the vowel starts.
- Closest English sound
- Closer to the p in “spin” than to the b in “bin” — English b is voiced, Mandarin b is not.
- Where learners slip
- Adding full voicing, which is harmless in isolation but makes b and p sound identical once you speak fast.
- Drill that fixes it
- Hold a strip of paper in front of your mouth: on b it must not move at all.
The final: -i
[i]
- What the mouth does
- Tongue high and front, lips spread. Long and tense.
- Closest English sound

- Where learners slip
- Shortening it to the i of “sit”.
- Drill that fixes it
- Smile hard and hold the vowel steady — no drift at the end.

Tone change you need to know
When a third tone is followed by another third tone, the first one is pronounced as a second tone. 你好 is written nǐ hǎo but said “ní hǎo”. The writing never changes — only the mouth does.
Third tone before any other tone. Before a first, second or fourth tone, the third tone loses its rise entirely and stays low. This “half third” is what you hear in almost all real sentences.
