Devoicing
/b/ → /p/
Typically resolves on its own by around age 4; worth a check-in if it persists.
What helps →
Touch the throat — /b/ buzzes, /p/ is silent. Have the child feel the vocal cord vibration on each /b/.

Voicing
Voiced Voiced sounds vibrate the vocal cords. Put your hand on your throat — voiced sounds buzz.

A child still substituting or distorting /b/ after age 3 is a good candidate for a speech-language evaluation — earlier if they're hard to understand or frustrated.

How to practice the /b/ sound
Practical starting points for parents and SLPs. Always follow your SLP's plan if your child is in therapy.
- 1 Lips together, voice on, then pop. /b/ closes the lips, starts the voice, then releases. The voice should start BEFORE the lips open — that's what makes it different from /p/.
- 2 Feel the throat buzz. /b/ uses the voice — touch the throat and feel it vibrate during the sound. Compare with /p/ (no buzz) to hear and feel the difference.
- 3 Practice with vowels. Once the voiced lip pop is steady, attach short vowels: "b-ah", "b-ee", "b-oh", then full words like "ball", "bat", "bee".
- 4 Slower than /p/. /b/ has slightly more voice and a softer release than /p/. Practice slowly so the voice has time to start before the lips open.
- 5 Use minimal pairs. Use pairs like pat/bat, pie/bye, pig/big so the child hears the voicing contrast and learns to control it.

/b/ sound — frequently asked questions
At what age should my child say the /b/ sound? +
Most children produce /b/ correctly by age 3. About half can do it by age 2. /b/ is one of the earliest English sounds.
Is it normal for my child to say "p" for "b"? +
Devoicing (saying "p" for "b") is developmentally typical up to about age 3. If it persists, an SLP check-in is worthwhile.
Why is the /b/ sound usually easy? +
/b/ uses visible lip closure, like /p/. The only added challenge is starting the voice — most children pick it up quickly.
How can I help my child practice /b/ at home? +
Have them touch their throat to feel the buzz, demonstrate the voiced lip pop in a mirror, and use minimal pairs (pat/bat) to train the ear.
When should we see a speech therapist about /b/? +
If /b/ is still being replaced with /p/ or omitted after age 3, it's worth seeing an SLP.
Can older children and adults still correct /b/? +
Yes — /b/ is highly treatable at any age. The voicing difference is easy to demonstrate and feel.
