Learning to distinguish between similar sounds is a crucial step toward clear and confident English pronunciation. One of the most common challenges for English learners is telling the difference between the sounds /p/ and /b/. On this page, we’ll explore how /p/ (the voiceless bilabial plosive) and /b/ (the voiced bilabial plosive) are produced, why they can be confusing, and how you can practice them effectively.
How to Distinguish the /p/ vs. /b/ Sounds?
What Are /p/ and /b/?
| Feature | /p/ | /b/ |
|---|---|---|
| Voicing | Voiceless (vocal cords do not vibrate) | Voiced (vocal cords do vibrate) |
| Place of Articulation | Bilabial (both lips come together) | Bilabial (both lips come together) |
| Manner of Articulation | Plosive (a burst of air when released) | Plosive (a burst of air when released) |
| Aspiration (puff of air) | Often aspirated at the start of a word (e.g., pin has a strong puff of air) | Not aspirated (less or no puff of air) |
How to Pronounce /p/ and /b/
/p/
/p/ is a voiceless bilabial plosive
-
Close your lips tightly (both lips together).
-
Build up air pressure behind your lips.
-
Release the lips suddenly—you’ll feel a small explosion of air.
-
No vocal cord vibration.
Notice in the diagram how the teeth and lips meet for /p/.
Listen to the audio to hear how the /p/ sound gently starts “pat.”
/b/
/b/ is a voiced bilabial plosive
-
Close your lips tightly (same lip position as /p/).
