o Vowels - are produced with little
restriction of the airflow from the
lungs out the mouth and or the nose.
o It can also carry pitch and loudness,
you can sing vowels or shout vowels .
They may be longer or shorter in
duration.
o Vowels can stand alone , they can be
produced without consonants before
or after them.

Example :
The vowel in Cat , the tongue is
low in the mouth with the
tongue tip forward, behind the
front teeth.

The upper two diagrams in Figure 6.4 show that
the tongue is high in the mouth in the
production of the vowels (i) and (u) in the
words he (hi) and who (hu). In he the front part
(but not the tip) of the tongue is raised ; in the
who it is the back of the tongue. (Prolong the
vowels of these words and try to feel the raised
part of your tongue). These are both high
vowels , and the (i) is a high front vowel while
the (u) is a high back vowel.

The vowel (ᴂ) in hack (hack) is produced
with the front pat of the tongue low in
the mouth, similar to the low vowel (a),
but with the front rather than the back
part of the tongue lowered. Say “ hack,
hah, hack, hah, hack, hah . . . “ and you
should feel your tongue moving forward
and the back in the low part of you
mouth.

Vowels also differ as to whether the lips are
rounding or spread.
Boot , put , boat , bore are the only rounded
vowels in English. They are produced with
pursed or rounded lips. You can get a feel for
the rounding by prolonging the word who, as if
you were an owl : whoooooooooooo. Now
pose for the camera and say cheese, only say it
with a prolonged vowel : cheeeeeeeeese.

A diphthong is a sequence of
two vowel sounds.
Diphthongs are present in
the phonetic inventory of
many languages, including
english.
Monophthongs are simple
vowels that we have studied so

Diphthong that occurs in English is the
vowel sound in boy (boi), which is the
vowel (o) of bore followed by (i),
resulting in (oi). The pronounciation
of any of these diphthongs may vary
from our description because of the
diversity of English speakers.

The words bean, bone, bingo, boom, bam and
bang are examples of words that contain
nasalized vowels. To show the nasalization of a
vowel in a narrow phonetic transcription, an
extra mark called diacritic – the symbol~
(tilde) in the case is placed over the vowel, as in
bean (bĩn) and bone (bõn).

In languages like French, Polish, and
portuguese, nasalized vowels occur
without nasal consonants. The french
word meaning “sound” is son (sõ). The
n in the spelling is not pronounced but
indicates that the vowel is nasal .

Stops and affricates belong to the
class of noncontinuants. There is
totally obstruction of the airstream
in the oral cavity. Nasal stop are
included although air does flow
continuously out the nose. All
other consonants, and all vowels,
are continuants, in which the
stream of air flows continuously
out of the mouth.

The non-nasal stops, the fricatives, and the affricates
form a major class of sounds called Obstruent. The
airstream may be fully obstructed, as in non-nasal
stops and affricates, or nearly fully obstructed as in
the production of fricatives.
Sounds that are not obstruent are sonorants.
Vowels, nasal stops (m,n), liquids (l,r) and glides
(j,w) are also sonorants. They produced with
much less obstruction to the flow of air than the
obstruents, which permits the air to resonate. Nasal
stops are sonorants because, although the air is
blocked in the mouth, it continues to resonate in
the nasal cavity.

In recognition of this fact linguists place the
obstruents, nasal stops, and liquids in a subclass
of consonants called consonantal, from which
the glides are excluded.
Here are some terms used to form subclasses of
consonantal sounds.
--Labials (p) (b) (m) (f) (v) (w) Labial sounds
are those articulated with the involvement of
the lips. They include the class of bilabial
sounds (p) (b) and (m), the labiodentals (f)
and (v), and the labiovelars (w).

--Coronals (ϴ) (õ) (t) (d) (n) (s) (z) (ʃ) (ʒ) (ʧ) (ʤ) (l)
(r) coronal sounds are articulated by raising the
tongue blade. Coronals include the interdentals
(ϴ) (õ), the alveolars (t) (d) (n) (s) (z), the palatals
(ʃ) (ʒ), the affricates (ʧ) (ʤ), and the liquids (l) (r).
--Anteriors (p) (b) (m) (f) (v) (ϴ) (õ) (t) (d) (n) (s) (z)
Anterior sounds are consonants produced in the
front part of the mouth, that is, from the alveolar
area forward. They include the labials, the
interdentals, and the alveolars.

-- Sibilants (s) (z) (ʃ) (ʒ) (ʧ) (ʤ) Another
class of consonantal sounds is
characterized by an acoustic rather than
an articulatory property of its members.
The friction created by sibiliants
produces a hissing sound, which is a
mixture of high-frequency sounds.

Tone languages - languages that use
the pitch of individual vowels or
syllables to contrast meaning of words.
Two kinds of tones:
If the pitch is level across the
syllables, we have a register tone .
If the pitch changes across the
syllable, whether from high to low or
vice versa, we have contour tone.

 Downdrift – the lowering of the pitch.
Languages that are not tone languages, such as
English, are called intonation languages.
The pitch contour of the utterance varies, but in
an intonation language as opposed to a tone
language, pitch is not used to distinguish words
from each other. Intonation may affect the
meaning of the whole sentences.
