Listening Lesson: Distinguishing /p/ and /b/

Welcome to your listening lesson. Today, we will practice hearing the difference between the /p/ and /b/ sounds. This is very important for clear English pronunciation.

The /b/ sound is a "voiced" sound. This means you use your voice. Put your hand on your throat. When you say "bbb," you will feel a vibration.
