P vs B Minimal Pairs
29 free P–B minimal pairs, sorted by position and ready to practice — the word list for voicing, when pear comes out as bear.
What are P vs B minimal pairs?
The /p/ and /b/ sounds are made in exactly the same place — both lips press together and release. The only difference is the voice: /b/ hums the vocal cords on, and /p/ leaves them off. A minimal pair puts that one switch on display: pear and bear, pat and bat, cap and cab.
This list targets voicing errors — when a voiceless /p/ picks up voice and turns into /b/ (so pear becomes bear), or a final /b/ loses its voice and hardens into /p/ (so cab becomes cap). Because the lips do the same thing for both sounds, the contrast is all about the voice turning on or off — and the minimal pair makes that difference matter, since pear and bear are two different words.
Voicing is one of the phonological processes covered in our guide to phonological processes.

Why minimal pairs work
Minimal pairs work because they make a sound matter. When the only thing separating two words is a single sound, saying that sound the wrong way changes what the child actually said — key becomes tea, cap becomes tap. That built-in feedback turns an abstract “say it this way” into a concrete mix-up the child can hear and fix.
This is the heart of the phonological (contrast) approach: instead of drilling a sound in isolation, you give the child a reason to keep the two sounds apart. Many children start to self-correct once they notice the listener heard the wrong word — the meaning contrast does the teaching. It is an evidence-informed technique widely used by speech-language pathologists, and it works just as well at the kitchen table as in the therapy room.
How to use P/B minimal pairs in therapy
A simple progression for SLPs and parents. If your child is in therapy, always follow your SLP's plan first.
- 1 Listen first. Read a batch of the pairs aloud so the child hears the P–B contrast many times, with no pressure to say anything back yet. This "auditory bombardment" tunes the ear before the mouth.
- 2 Point to the right one. Lay out a few picture pairs, say one word, and have the child point to the matching picture. This checks that they can hear the difference before they have to produce it.
- 3 Copy you. Have the child repeat each word after you, starting with the picture pairs. Model slowly and let them watch your mouth.
- 4 Say it on their own. Have the child name the picture without a model. If both words come out the same, that mix-up is the teaching moment — show how the sound changes which word they said.
- 5 Carry it over. Move from single words into short phrases and everyday talk, and send a few pairs home so practice keeps going between sessions.

P vs B minimal pairs — frequently asked questions
What are P vs B minimal pairs? +
P vs B minimal pairs are words that differ by only one sound — a /p/ in one and a /b/ in the other — such as pear/bear, pat/bat, and cap/cab. Both sounds are made with the lips; the only difference is whether the voice is on, which is exactly what the child practices.
What phonological process do P/B minimal pairs target? +
They target voicing errors — either prevocalic voicing, where a voiceless /p/ is produced as a voiced /b/ ("pear" becomes "bear"), or final devoicing, where a voiced /b/ at the end of a word hardens into /p/ ("cab" becomes "cap"). The contrast shows the child that turning the voice on or off changes the word.
How do you use P and B minimal pairs in speech therapy? +
Read the pairs aloud so the child hears the contrast, have them point to the word you say, then repeat each word, name the pictures on their own, and finally use the words in phrases and everyday talk. A helpful trick is to have the child rest a hand on their throat — /b/ makes a buzz they can feel, and /p/ does not.
When do the P and B sounds develop? +
Both /p/ and /b/ are early sounds, reaching 90% mastery by around age 3 (McLeod & Crowe, 2018; Crowe & McLeod, 2020), and voicing errors usually resolve early as well. If a child is mixing up /p/ and /b/ past the toddler years, or is hard to understand, it is a good time to talk with a speech-language pathologist. This page is informational and is not a diagnosis.
