Pronunciation Course

In today’s lesson we’re going to practice our pronunciation a bit and also learn when to use the words proof and prove, belief and believe.

These pairs of words are different by only one sound – the F sound and the V sound. We make these by using the same mouth position, with the top teeth touching the bottom lip. The only difference is that for the F sound we only blow air, and for the V sound we use our voice.

So first let’s practice pronouncing each word – listen and repeat after me:



Now say both: proof – prove



Now say both: belief – believe

In my American English Pronunciation Course, we do a LOT of practice with similar sounds like these, which non-native English speakers often mispronounce. The course will help you speak English more clearly and confidently.

OK, so we know the pronunciation difference between proof/prove, belief/believe, but when do we use each one?

Proof and belief are nouns, and prove and believe are verbs. Let’s look at some examples:

The verb prove is the action of showing with certainty that something is true.

  • Hopefully the results of this experiment will prove that the new medicine is safe.
  • My physics class is proving to be more difficult than I expected.
