About this test
About the Minimal Pairs Pronunciation Test (C1 Advanced)
Minimal pairs are words that differ by only one sound, such as ship and sheep or pull and pool. If you mix the two sounds, the listener may hear a completely different word. This test focuses on the vowel pairs learners confuse most: short and long I, short A and short E, short OO and long OO, and short U. The computer shows you which word it heard.
Why practise this at C1 level
At C1 small errors stand out more, because everything else sounds fluent. These advanced sentences use academic and professional vocabulary, long words and complex stress, so you can polish the last sounds that still give away your first language.
How to get it right
- Look at what was heard under each red word
- Notice which vowel you used instead
- Practise the pair slowly, then at normal speed
- Use the individual vowel tests for extra practice
