Pronunciation exercises: \uː\ vs \ʊ\

Together with the page possible pronunciation difficulties, this page sets out some common words that can be used to become more aware of how you can improve your pronunciation of the vowel sounds **/uː/** and **/ʊ/**.

/uː/ is longer than /ʊ/. /uː/ is often a diphthong [ʉw] or [uw].

A simple way of introducing the difficulty is with common words with /ʊ/ like *good* and *foot*; words with /uː/ are much more common and will probably pose no problem to students.

Since spelling is of little help, separating both sounds is a bigger challenge than the case of /ɪ/ vs /iː/.

Note that some native speakers don't make a distinction between /uː/ and /ʊ/. This happens mainly in Scotland, but also in Ulster, and Singapore.

## /uː/

A word can't end in stressed /ʊ/. In bold words that can't be confused.

* With "oo": boot - choose - cool - fool - loose - moon - pool - root - school - soon - stool - **too** - tool
* With "u" and magic e: absolute - include - June - rule
* With "u": brutal - conclusion - **flu** - truth
* With "ew": **blew - brew - chew - crew - drew - screw - threw**
* With "ou": group - soup -  **through - you** - youth
* With "o": lose - move - tomb - **who**

## /ʊ/

* With "oo":  book - cook - foot - good - hook - look - shook - stood - took - wood - wool
* With "u":  bull - bullet - bush - cushion - full - pudding - pull - push - put - sugar
* With "ou": could - would - should
* With "o": bosom - wolf - woman

Normally only a few consonants follow /ʊ/.

* /d/: could - good - hood - pudding - should - stood - wood - would
* /g/: sugar
* /k/: book - brook - cook - crook - hook - rook - shook - took
* /l/: bull - bullet - full - pull - wolf - wolves - wool
* /m/: woman
* /ʃ/: bush - cushion - push
* /t/: chutzpah - foot - put - soot
* /tʃ/: butch - butcher

/uː/ then /ʊ/

* boot - foot; food - good; pool - wool;

## /uː/ or /ʊ/

The following words are mainly pronounced with /uː/, but some people pronounce them with /ʊ/. The proportion of people pronouncing /ʊ/ is decreasing in time.

* /f/: hoof - roof
* /m/: bedroom - blooming *(swear word)* - broom - groom - mushroom - room - roomy
* /t/: root (/rʊt/ *is heard only in American English)*

## Anticipated pronunciation difficulties depending on L1

### Spanish

Most Spanish speakers have difficulty distinguishing between **/uː/** and **/ʊ/**.
While **/uː/** is very similar to the Spanish letter "**u**", it is actually much longer. **/ʊ/** is much shorter and of a different quality.

Many teachers don't teach the difference explicitly in the belief that students will imitate the teacher. However some Spanish speakers are very difficult to convince that *boot* and *book* have a different vowel or that *pull* and *pool* are not homophones.
