LESSON 2-3
English Vowels
Unlike consonants, vowels
are produced with no oral obstruction at all.
Note that vowels usually constitute the main part/peak of a
syllable. In classifying the vowels, we
traditionally use 4 criteria:
1. How high is the tongue?
2. What part of the tongue is raised or lowered?
3. What is the position of the lips?
4. How tense or lax is the articulation?
Let us consider examples for
the first 3, before considering the notion of tenseness/laxness. The vowel in the word seen is a high
front unrounded vowel [i] in that the front part of the tongue is raised
and the lips are unrounded as we articulate the vowel. Compare that to the vowel in soon,
where we have the high back rounded vowel [u]. Notice that for [u], the back part of the tongue is raised and
the lips are rounded. The best way to
see the difference is by saying these words aloud and slowly, and by somewhat accentuating/exaggerating
the vowel.
Now, as far as the tense vs.
lax distinction, it is important to note that actually these terms are “cover
terms” that refer to a number of phonetic properties, including height,
duration and diphthongization. Again
the best way to show this is by comparing vowels in pairs of words. Compare seen and sin. Both of the i vowels are high front
and unrounded. The one in seen
is tense: it is produced by slightly higher tongue position; it is longer in
duration; and it is diphthongized (i.e., a vowel followed by a glide – either
[y] or [w]). In sin, on the other hand, we have
a lax i. Similarly, compare the
name Luke and the verb look. The former has a high back tense rounded vowel, while the
latter contains the lax counterpart.
Now I would like you to
study Figure 1 (vowel chart) on page 49 carefully.
Once you are familiar with
the consonants and vowels of English, you’ll be ready to work on Exercise 2
(which requires online discussion via Online
Conferencing).
Same grouping as
before—I’ll change them for the next discussion.
