Back high vowels: /u/ vs /ʊ/

 

Back high vowels: /u/ vs /ʊ/ 

Both /ʊ/ and  /u/ are high back vowels. So both sounds are produced in the back of the mouth with the tongue raised high.  The difference between them lies in the tenseness of the lips. The  /ʊ/ sound is lax, and the /u/ sound is tense. To make /u/, we make the lips tense so that the lips are rounded and protruding. With /ʊ/, we raise the tongue and let the air out.
