Below is a list of words that vary only by one having the sound /ɪ/ and the other the sound /i:/.
You can use this list to practise the sounds, or as a list of words to be careful in pronouncing.
As indicated by the /:/ part of its symbol, /i:/ is a longer sound than /ɪ/ and pronouncing it this way can help distinguish between the two in the pairs of words below. You will also notice, however, that /ɪ/ does not have a dot over it, making it a different mouth position from /i:/. The sound /i:/ is said with the mouth much more spread, something like a broad smile. This is why we say "cheese" rather than "chiz" (or "whizz") when we take photos.
