Hello again. Last time, you counted syllables and found primary stress by listening rather than counting letters. Today you will use the same sound-first approach on a smaller scale: one sound inside a word. You will compare minimal pairs, then use them to show why written English is an unreliable pronunciation guide for contemporary RP.
The aim is not to memorise a long list of pairs. It is to be able to hear a contrast, identify the sound that changed, and check whether the spelling represents that change clearly.
One changed sound, one changed word · About 7 minutes
A minimal pair consists of two words with different meanings whose pronunciations differ by just one sound in the same position. In contemporary RP, ship /ʃɪp/ and sheep /ʃiːp/ are a minimal pair. Both begin with /ʃ/ and end with /p/; only the vowel differs. The spellings look more different than the pronunciations are: i and ee each represent one vowel sound here.
The same idea applies to consonants. Pin /pɪn/ and bin /bɪn/ differ only in their first sound. A minimal pair therefore tells you something important about spoken English: changing that sound can change which word a listener understands.
Minimal Pairs in English | English Pronunciation
Watch Minimal Pairs in English | English Pronunciation from Billie English for a spoken explanation of what counts as a minimal pair.
Watch the definition, paying particular attention to the distinction between pronunciation and spelling. Continue with ship and sheep to hear the one-vowel contrast. Then skip to consonant pairs, where the changed sound is at the beginning of the word. Focus on what stays the same in each pair, not on the number of letters.
The slashes around /ʃɪp/ and /ʃiːp/ show that these are sound transcriptions, not alternative spellings. This is what makes IPA useful: it lets you compare pronunciations without being distracted by written forms.

Read a small selection of pairs from EnglishClub’s Minimal Pairs. Its lists group words by the sound contrast, which is more useful for this lesson than grouping them by written letters.
Read EnglishClub’s Minimal Pairs for its definition and a compact selection of vowel and final-consonant contrasts.
At the top of the page, read the definition beginning one sound. Under “Vowel Sounds with audio,” scan the listed pairs from sit seat to cot caught; focus especially on sit/seat, bad/bed, and cot/caught. Then, under “Final Consonant Sounds with audio,” scan from back bag to bus buzz. The entries link to separate audio pages, but you only need the pairs on this page for now.
Consider cot /kɒt/ and caught /kɔːt/. Their written forms differ in several letters, yet their RP pronunciations differ in one vowel sound. The letters aught in caught do not amount to several sounds between /k/ and /t/. Conversely, bus /bʌs/ and buzz /bʌz/ show that a final contrast can matter even when the rest of the word is unchanged. We will work on producing such final contrasts later; today, the task is to identify them.
A useful way to inspect any proposed minimal pair is to put the pronunciations side by side and locate the single substitution:
| Words | Contemporary RP | Only sound that changes |
|---|---|---|
| ship / sheep | /ʃɪp/ · /ʃiːp/ | /ɪ/ versus /iː/ |
| cot / caught | /kɒt/ · /kɔːt/ | /ɒ/ versus /ɔː/ |
| bus / buzz | /bʌs/ · /bʌz/ | /s/ versus /z/ |
In the first two rows, do not interpret the contrast as length alone. The vowel symbols also identify different vowel qualities. You will hear and produce those distinctions in detail in later modules.
What minimal pairs reveal—and what they do not · About 9 minutes
A minimal pair isolates a meaningful sound difference. It does not, by itself, prove that every spelling is unpredictable. For example, the letters p and b in pin/bin give a fairly clear clue to the sound difference. To see the larger spelling problem, compare several kinds of evidence.
First, the same spelling can have different pronunciations. Compare live in “They live nearby” /lɪv/ with live in “live music” /laɪv/. The written word is identical, but its vowel—and its meaning—changes. These two uses form a minimal contrast in pronunciation: /lɪv/ and /laɪv/ differ by one vowel sound. The spelling alone cannot tell you which to say; the meaning and context can.
Second, different spellings can represent the same pronunciation. In contemporary RP, hole and whole are both /həʊl/. These are homophones, not a minimal pair: there is no sound difference to isolate. Keeping that distinction clear matters. Minimal pairs have one changed sound; homophones have none, despite their different written forms.
Third, the size of a spelling difference need not match the size of a sound difference. Cot/caught differ in many written characters but only one spoken vowel. In sea /siː/ and she /ʃiː/, only the initial consonant changes in speech, although the written vowel sequences look different too. Counting changed letters would give the wrong analysis of both pairs.
These observations lead to a practical rule: use spelling to recognise a word, but use sound evidence to establish its pronunciation. For an unfamiliar word, a UK dictionary recording and IPA transcription are better checks than a guess based solely on its letters.

The next video mixes words pronounced differently with words pronounced alike. It is useful precisely because you must distinguish a minimal pair from a homophone pair rather than assuming every two written words have different sounds.
15 MINIMAL PAIRS. Do you know the right pronunciation?
Watch selected moments from LetThemTalkTV’s 15 MINIMAL PAIRS. Do you know the right pronunciation? to hear both types of comparison. Despite the title, some pairs in this video are homophones rather than minimal pairs.
In hole and whole, listen for the absence of a sound contrast despite the different spellings. In the final comparisons, listen first for the vowel difference in ship/sheep, then for the matching pronunciation of waist/waste. The latter, like hole/whole, is a homophone pair.
After listening, a brief recording can make the distinction more concrete. Record ship, sheep; hole, whole at an unhurried pace. On playback, attend to just one feature: whether the first pair has two distinguishable vowels while the second pair sounds the same. Use a UK dictionary recording if you need to check either pronunciation. This is a sound check, not a request to change every feature of your accent at once.
A dependable way to use a new pair · About 5 minutes
When you encounter two similar English words, work in this order:
- Hear or check both pronunciations. Avoid deciding from spelling alone.
- Compare their IPA transcriptions sound by sound. A group of letters such as sh may represent one sound, /ʃ/; a diphthong such as /aɪ/ is one vowel sound for this comparison.
- Name the result accurately. If exactly one sound differs and the meanings differ, you have a minimal pair. If the pronunciations are identical, you have homophones. If several sounds differ, neither label fits.
This method turns minimal-pair practice into more than repetition. It tells you what a listener must hear, while preventing written English from supplying a misleading answer.
Minimal pairs demonstrate how much meaning can depend on one spoken sound: ship/sheep differ in a vowel, and bus/buzz in a final consonant. But letters and sounds do not correspond consistently: live has two pronunciations under one spelling, hole/whole have one pronunciation under two spellings, and cot/caught have a much larger difference on the page than in speech.
Next, you will make your listening more systematic with a listen–record–compare routine, concentrating on one feature of a spoken sentence at a time.
