Minimal Pairs /əʊ/ and /ɔ:/

so and saw


The sound of /əʊ/ (as in "O", "oh" and "owe") is a diphthong, meaning two vowel sounds blended into one. You should be able to see the mouth moving from one position to the other while making the sound, with the mouth becoming smaller and rounder. You can emphasize and control this by holding your hand in front of your mouth and bringing the fingers in towards each other as you move from the first part of the sound to the last part.
The sound of /ɔ:/ (as in "or" and "awe") is a single long sound. The mouth doesn't move while making this sound, and you can pronounce it as long as you have breath.
