Vowels in Unstressed Syllables in Content Words
|Vowels in stressed syllables of a content word are usually pronounced in the same way whether they are made prominent or not (see also Unit 10):|
A: Is she a DOCtor? /dokt∂/
B: NO, her SISter's a doctor. /dokt∂/
The vowel in a one-syllable content word doesn't change itspronunciation, although the vowel in a one-syllable function word can (see Unit 21):
content word: It's a big CAT. /big/ It's really BIG. /big/
function word: It's for you. /f∂/ but: WHAT'S it FOR? /fo:/
|However, the vowels in unstressed syllables of a content word can varya lot. In slow, careful speech the vowel may have its full form, butin normal speech these vowels are often reduced to /∂/ (or sometimes for /ι/). For example, 'calendar' can be said /kælιnd∂/ or /kæl∂nd∂/; the second vowel varies from /ι/ to /∂/. Here are some more words which have variable vowels in unstressed syllables.|
It is not essential to reduce these vowels in your own speech in orderto be understood, although reduced vowels usually sound more naturaland fluent.
Important for listening!
In some words, when an unstressed syllable ending in a vowel isfollowed by another unstressed syllable beginning with a vowel, the twosyllables may merge into one. This only happens in normal speech; inslow, careful speech both syllables are said:
slow speech: casual /kæ3.ju.el/ = three syllables
normal speech: casual /kæ3.j∂l/ = two syllables
Other words like this include:
virtual, actual, adverbial, colonial, studious, obedient, ingredient, gradient
Listen and compare the pronunciation of these words, first saidslowly and carefully, and then used in normal speech. In which wordsdoes the pronunciation of the highlighted vowel sound change (write C),and in which is there no change (write NC)? (Some of these words aregiven in B opposite.)
Now listen again and repeat, first the words alone and then the sentences with the words in context.
You will hear short definitions. After each definition, press'pause', choose an answer from the box and say it aloud. (Use slow,careful speech.) When you press 'play' again you will hear the correctanswer.
|Use the words from exercise 2 to complete these sentences.|
Example: The graph goes from zero to infinity . (/ιn'fιn∂ti/)
1 I was late again and my boss was __________ with me.
2 He was a __________ boy who was happiest when he was reading.
3 Since he appeared on TV he's become a bit of a __________.
4 The country used to be an important __________ power.
5 The __________ of people didn't bother to vote in the election.
6 I want you to underline the __________ in each sentence.
7 Honey's the main __________ in the sauce.
8 Just out of __________, how old are your sisters?
9 It seemed to defy the laws of __________.
10 Because of the snow, we were __________ prisoners in our own home.
Now say the sentences aloud (with the words you have written pronouncedas in normal speech). Then listen and check your answers.
