The /B/Sound: Speech Therapy Guide & Practice Games

The /B/ sound is a voiced bilabial stop. It is produced the same way as /P/ (both lips pressed together then released), but with the vocal cords vibrating. It is one of the earliest sounds children develop, often appearing in babbling ("baba") in the first year of life.

How to Make the /B/ Sound

Press both lips firmly together, just like for /P/. Turn your voice on — you should feel a vibration in your throat. Build up a small amount of air pressure behind your lips, then quickly pop them open to release a burst of voiced air. The sound should be a deeper, buzzier version of /P/.

IPA Symbol: /b/

Most children master the /B/ sound by age 2-3. Along with /P/ and /M/, it is among the earliest consonants to develop. "Baba" and "bye-bye" are often among a child's first words.

Common /B/ Sound Errors

  • error_outlineSubstituting /P/ for /B/ — devoicing (e.g., "pat" for "bat")
  • error_outlineWeak lip closure leading to an unclear sound
  • error_outlineOmitting /B/ at the end of words
  • error_outlineNasal emission: air going through the nose
  • error_outlineNot maintaining voicing throughout the sound

Tips for Practicing the /B/ Sound at Home

Evidence-based strategies parents can use to support /B/ sound practice.

1

Use the "buzzy lips" cue: have your child press their lips together and hum to feel the vibration before popping them open.

2

Contrast /B/ (voiced) with /P/ (voiceless): place a hand on the throat — /B/ vibrates, /P/ does not.

3

Start with babbling: "ba-ba-ba," "bo-bo-bo," "bee-bee-bee" — this is natural for young children.

4

Use motivating /B/ words: "ball," "balloon," "bear," "bird," "book," "bubbles," "bus."

5

Play blowing bubbles — the word "bubbles" itself is great /B/ practice, and the activity is motivating.

6

For final /B/, practice words like "tub," "crib," "bib" — have your child feel their lips close at the end of the word.

7

Sing songs with /B/ words: "B-I-N-G-O," "The Bus Song," "Baby Bumble Bee."

Frequently Asked Questions About the /B/ Sound

Common questions parents ask about the /B/ sound in speech therapy.

When should my child be able to say the /B/ sound?expand_more
Most children master /B/ by age 2-3. It typically appears in babbling ("baba") around 6-10 months and is one of the earliest consonant sounds to develop in words.
My child says /P/ instead of /B/. What should I do?expand_more
This is called devoicing — your child is using the correct lip position but not turning on the voice. Practice by having your child hum ("mmm") and then pop the lips open to transition into /B/. The humming activates the vocal cords.
How is /B/ related to /P/ and /M/?expand_more
All three sounds are bilabial (both lips). /P/ is voiceless (no vibration), /B/ is voiced (vibration), and /M/ is voiced and nasal (air through the nose). Children typically develop all three around the same time because they use the same lip position.
Why does my child leave off /B/ at the end of words?expand_more
Dropping final consonants is a normal pattern in children under age 3. If your child consistently omits final /B/ after age 3, practice words like "tub," "crib," and "bib," emphasizing the lip closure at the end.
Are there any red flags with /B/ production?expand_more
If your child cannot produce /B/ by age 3, or if you notice air consistently escaping through the nose during /B/ (nasal emission), an evaluation by a speech-language pathologist is recommended. Nasal emission could indicate a structural or functional issue that needs assessment.
