The lips are active articulators that play a major role in producing speech sounds.

They are responsible for:

• Producing bilabial sounds like /p/, /b/, and /m/
• Controlling mouth shape (rounding, closing, opening)
• Regulating airflow during speech

For example:

• The /p/ sound is produced by closing the lips and releasing air suddenly

Weak lip control may result in:

• Reduced speech clarity
• Difficulty producing specific sounds
• Feeding or oral motor challenges
