Question

Among the following, which one is a bilabial sound?

• A. /p/
• B. /b/
• C. /m/
• D. All of the three

Answer 1

Answer:

D. All of the three

• A bilabial sound is produced by bringing both lips together to block or restrict airflow.

👉 The following are bilabial consonants in English:

• /p/ → voiceless bilabial plosive (as in pen)

• /b/ → voiced bilabial plosive (as in bat)

• /m/ → bilabial nasal (as in man)

All three involve both lips (bi = two, labial = lips).
