/b/

Press both lips firmly together to block the airflow completely, just like for /p/. Build up a small amount of air pressure, then release your lips quickly. The key difference: your vocal cords should vibrate throughout. Place your fingers on your throat while saying "ba" - you should feel a buzzing sensation from the moment you start the sound.

Unlike /p/, the /b/ sound has very little aspiration (no strong puff of air). When you say "bat," the release is softer and more muffled compared to the explosive burst in "pat."

Both sounds share the exact same lip position - they differ in voicing and aspiration:

• /b/ is voiced (throat vibrates) with minimal aspiration
• /p/ is voiceless (no vibration) with strong aspiration at word beginnings

At the start of words, American listeners rely heavily on that aspiration difference. If you add too much air burst to /b/, it may sound like /p/.

In final position (like "rub" or "cab"), /b/ naturally loses some of its voicing - this is normal even for native speakers. The key to maintaining the contrast with /p/ is lengthening the vowel before /b/. Compare "cab" (longer "a") versus "cap" (shorter "a"). The vowel duration is often more important than the voicing itself.

Practice minimal pairs like "bat/pat," "buy/pie," and "cab/cap." Focus on keeping your throat buzzing for /b/ and feeling that strong air puff only for /p/. For word-final /b/, concentrate on stretching the vowel before it rather than forcing voicing at the end.
