Sound Segments
•  Knowing a language includes knowing the sounds of that
language
•  Phonetics is the study of speech sounds
•  We are able to segment a continuous stream of speech
into distinct parts and recognize the parts in other words
•  Everyone who knows a language knows how to segment
sentences into words and words into sounds

Identity of Speech Sounds
•  Our linguistic knowledge allows us to ignore
nonlinguistic differences in speech (such as
individual pitch levels, rates of speed, coughs)
•  We are capable of making sounds that are not
speech sounds in English but are in other
languages
–  The click tsk that signals disapproval in English is a
speech sound in languages such as Xhosa and Zulu
where it is combined with other sounds just like t or k
is in English

Identity of Speech Sounds
•  The science of phonetics aims to describe all the
sounds of all the world’s languages
–  Acoustic phonetics: focuses on the physical
properties of the sounds of language
–  Auditory phonetics: focuses on how listeners
perceive the sounds of language
–  Articulatory phonetics: focuses on how the vocal
tract produces the sounds of language

The Phonetic Alphabet
•  Spelling, or orthography, does not consistently represent the
sounds of language
•  Some problems with ordinary spelling:
–  1. The same sound may be represented by many letters or combination
of letters:
he people key
believe seize machine
Caesar seas
see amoeba
–  2. The same letter may represent a variety of sounds:
father village
badly made
many

– 3. A combination of letters may represent a
single sound
shoot character Thomas
either physics rough
coat deal
– 4. A single letter may represent a combination
of sounds
xerox

– 4. Some letters in a word may not be
pronounced at all
autumn sword resign
pterodactyl lamb corps
psychology write knot
– 5. There may be no letter to represent a
sound that occurs in a word
cute
use

•  In 1888 the International Phonetic
Alphabet (IPA) was invented in order to
have a system in which there was a one-
to-one correspondence between each
sound in language and each phonetic
symbol
•  Someone who knows the IPA knows how
to pronounce any word in any language

•  Dialectal and individual differences affect
pronunciation, but the sounds of English
are:

•  Using IPA symbols, we can now represent
the pronunciation of words
unambiguously:

Articulatory Phonetics
•  Most speech sounds are produced by pushing air
through the vocal cords
–  Glottis = the opening between the vocal cords
–  Larynx = ‘voice box’
–  Pharynx = tubular part of the throat above the larynx
–  Oral cavity = mouth
–  Nasal cavity = nose and the passages connecting it to the throat
and sinuses

Consonants: Place of Articulation
•  Consonants are sounds produced with some
restriction or closure in the vocal tract
•  Consonants are classified based in part on
where in the vocal tract the airflow is being
restricted (the place of articulation)
•  The major places of articulation are:
bilabial, labiodental, interdental, alveolar, palatal,
velar, uvular, and glottal

Consonants:
Place
of
Ar0cula0on

•  Bilabials:
[p]
[b]
[m]

–  Produced
by
bringing
both
lips
together

•  Labiodentals:
[f]
[v]

–  Produced
by
touching
the
bo=om
lip
to
the
upper
teeth

•  Interdentals
[θ]
[ð]

–  Produced
by
pu@ng
the
0p
of
the
tongue
between
the

teeth

•  Alveolars: [t] [d] [n] [s] [z] [l] [r]
–  All of these are produced by raising the tongue to the alveolar
ridge in some way
•  [t, d, n]: produced by the tip of the tongue touching the alveolar
ridge (or just in front of it)
•  [s, z]: produced with the sides of the front of the tongue raised but
the tip lowered to allow air to escape
•  [l]: the tongue tip is raised while the rest of the tongue remains down
so air can escape over the sides of the tongue (thus [l] is a lateral
sound)
•  [r]: air escapes through the central part of the mouth; either the tip
of the tongue is curled back behind the alveolar ridge or the top of
the tongue is bunched up behind the alveolar ridge

•  Palatals:
[ʃ]
[ʒ]
[ʧ]
[ʤ][ʝ]

–  Produced
by
raising
the
front
part
of
the
tongue
to
the
palate

•  Velars:
[k]
[g]
[ŋ]

–  Produced
by
raising
the
back
of
the
tongue
to
the
soI
palate
or
velum

•  Uvulars:
[ʀ]
[q]
[ɢ]

–  Produced
by
raising
the
back
of
the
tongue
to
the
uvula

•  Glo5als:
[h]
[Ɂ]

–  Produced
by
restric0ng
the
airﬂow
through
the
open
glo@s
([h])
or
by

stopping
the
air
completely
at
the
glo@s
(a
glo5al
stop:
[Ɂ])

Consonants: Manner of Articulation
•  The manner of articulation is the way the
airstream is affected as it flows from the lungs
and out of the mouth and nose
•  Voiceless sounds are those produced with the
vocal cords apart so the air flows freely through
the glottis
•  Voiced sounds are those produced when the
vocal cords are together and vibrate as air
passes through

Consonants:
Manner
of
Ar0cula0on

•  The
voiced/voiceless
dis0nc0on
is
important
in

English
because
it
helps
us
dis0nguish
words
like:

rope/robe

ﬁne/vine

seal/zeal

[rop]/[rob]

[faɪn]/[vaɪn]

[sil]/[zil]

•  But
some
voiceless
sounds
can
be
further

dis0nguished
as
aspirated
or
unaspirated

aspirated

unaspirated

pool
[phul]

spool

[spul]

tale
[thel]

stale

[stel]

kale
[khel]

scale

[skel]

Consonants: Manner of Articulation
•  Oral sounds are those produced with the velum raised
to prevent air from escaping out the nose
•  Nasal sounds are those produced with the velum
lowered to allow air to escape out the nose
•  So far we have three ways of classifying sounds based
on phonetic features: by voicing, by place of
articulation, and by nasalization
–  [p] is a voiceless, bilabial, oral sound
–  [n] is a voiced, alveolar, nasal sound

Consonants:
Manner
of
Ar0cula0on

•  Stops:
[p]
[b]
[m]
[t]
[d]
[n]
[k]
[g]
[ŋ]
[ʧ][ʤ]
[Ɂ]

– Produced
by
completely
stopping
the
air
flow
in

the
oral
cavity
for
a
frac0on
of
a
second

•  All
other
sounds
are
con;nuants,
meaning
that
the

airflow
is
con0nuous
through
the
oral
cavity

•  Frica;ves:
[f]
[v]
[θ]
[ð]
[s]
[z]
[ʃ]
[ʒ]
[x]
[ɣ]
[h]

– Produced
by
severely
obstruc0ng
the
airflow
so
as

to
cause
fric0on

Consonants:
Manner
of
Ar0cula0on

•  Aﬀricates:
[ʧ]
[ʤ]

–  Produced
by
a
stop
closure
that
is
released
with
a
lot
of

fric0on

•  Liquids:
[l]
[r]

–  Produced
by
causing
some
obstruc0on
of
the
airstream
in

the
mouth,
but
not
enough
to
cause
any
real
fric0on

•  Glides:
[j]
[w]

–  Produced
with
very
li=le
obstruc0on
of
the
airstream
and

are
always
followed
by
a
vowel

Consonants:
Manner
of
Ar0cula0on

•  Approximants:
[w]
[j]
[r]
[l]

–  Some0mes
liquids
and
glides
are
put
together
into
one
category
because
the

ar0culators
approximate
a
fric0onal
closeness
but
do
not
actually
cause

fric0on

•  Trills
and
ﬂaps:
[r]*
[ɾ]

–  Trills
are
produced
by
rapidly
vibra0ng
an
ar0culator

–  Flaps
are
produced
by
a
ﬂick
of
the
tongue
against
the
alveolar
ridge

•  Clicks:

–  Produced
by
moving
air
in
the
mouth
between
various
ar0culators

–  The
disapproving
sound
tsk
in
English
is
a
consonant
in
Zulu
and
some
other

southern
African
languages

–  The
lateral
click
used
to
encourage
a
horse
in
English
is
a
consonant
in
Xhosa

*The textbook uses [r] to represent the central liquid as in the word ready rather than as
a trill

Vowels

•  Vowels
are
classiﬁed
by
how
high
or
low
the
tongue
is,
if
the

tongue
is
in
the
front
or
back
of
the
mouth,
and
whether
or

not
the
lips
are
rounded

•  High
vowels:
[i] [ɪ] [u] [ʊ]

•  Mid
vowels:
[e]
[ɛ]
[o]
[ə]
[ʌ]
[ɔ]

•  Low
vowels:
[æ]
[a]

•  Front
vowels:
[i]
[ɪ]
[e]
[ɛ]
[æ]

•  Central
vowels:
[ə]
[ʌ]

•  Back
vowels:
[u]
[ɔ]
[o]
[æ]
[a]

Vowels

•  Round
vowels:
[u]
[ʊ]
[o]
[ɔ]

–  Produced
by
rounding
the
lips

–  English
has
only
back
round
vowels,
but
other
languages
such
as
French
and

Swedish
have
front
round
vowels

•  Diphthongs:
[aɪ]
[aʊ]
[ɔɪ]

–  A
sequence
of
two
vowel
sounds
(as
opposed
to
the
monophthongs
we
have

looked
at
so
far)

•  Nasaliza;on:

–  Vowels
can
also
be
pronounced
with
a
lowered
velum,
allowing
air
to
pass

through
the
nose

–  In
English,
speakers
nasalize
vowels
before
a
nasal
sound,
such
as
in
the
words

beam,
bean,
and
bingo

–  The
nasaliza0on
is
represented
by
a
diacri0c,
an
extra
mark
placed
with
the

symbol:

Vowels
•  Tense vowels:
–  Are produced with
greater tension in the
tongue
–  May occur at the end of
words
•  Lax vowels:
–  Are produced with less
tongue tension
–  May not occur at the end
of words

Major Phonetic Classes
•  Noncontinuants: the airstream is totally obstructed in
the oral cavity
–  Stops and affricates
•  Continuants: the airstream flows continuously out of the
mouth
–  All other consonants and vowels
•  Obstruents: the airstream has partial or full obstruction
–  Non-nasal stops, fricatives, and affricates
•  Sonorants: air resonates in the nasal or oral cavities
–  Vowels, nasal stops, liquids, and glides

Major
Phone0c
Classes:
Consonantal

•  Consonantal:
there
is
some
restric0on
of
the
airﬂow

during
ar0cula0on

–  All
consonants
except
glides

•  Consonantal
sounds
can
be
further
subdivided:

–  Labials:
[p]
[b]
[m]
[f]
[v]
[w]
[ʍ]

•  Ar0culated
with
the
lips

–  Coronals:
[θ]
[ð]
[t]
[d]
[n]
[s]
[z]
[ʃ]
[ʒ]
[ʧ][ʤ]
[l]
[r]

•  Ar0culated
by
raising
the
tongue
blade

Major
Phone0c
Classes

•  Consonantal
categories
cont.:

–  Anteriors:
[p]
[b]
[m]
[f]
[v]
[θ]
[ð]
[t]
[d]
[n]
[s]
[z]

•  Produced
in
the
front
part
of
the
mouth
(from
the
alveolar
area

forward)

–  Sibilants:
[s]
[z]
]
[ʃ]
[ʒ]
[ʧ][ʤ]

•  Produced
with
a
lot
of
fric0on
that
causes
a
hissing
sound,
which
is

a
mixture
of
high-‐frequency
sounds

•  Syllabic
Sounds:
sounds
that
can
func0on
as
the
core

of
a
syllable

–  Vowels,
liquids,
and
nasals

Prosodic
Features

•  Prosodic,
or
suprasegmental
features
of
sounds,

such
as
length,
stress
and
pitch,
are
features
above

the
segmental
values
such
as
place
and
manner
of

ar0cula0on

•  Length:
in
some
languages,
such
as
Japanese,
the

length
of
a
consonant
or
a
vowel
can
change
the

meaning
of
a
word:

–  biru
[biru]
“building”

biiru
[biːru]
“beer”

–  saki
[saki]
“ahead”

sakki
[sakːi]
“before”

Prosodic Features
•  Stress: stressed syllables are louder, slightly
higher in pitch, and somewhat longer than
unstressed syllables
–  The noun digest has the stress on the first syllable
–  The verb digest has the stress on the second syllable
–  English is a stress-timed language, meaning that at
least one syllable is stressed in an English word
•  French functions differently, so when English speakers learn
French they put stress on certain syllables which contributes
to their foreign accent

Tone
and
Intona0on

•  Tone
languages
are
languages
that
use
pitch

to
contrast
the
meaning
of
words

•  For
example,
in
Thai,
the
string
of
sounds
[naː]
can

be
said
with
5
diﬀerent
pitches
and
can
thus
have

5
diﬀerent
meanings:

Tone and Intonation
•  Intonation languages (like English) have
varied pitch contour across an utterance,
but pitch is not used to distinguish words
–  However, intonation may affect the meaning of a
whole sentence:
•  John is here said with falling intonation is a statement
•  John is here said with rising intonation is a question

Phonetics of Signed Languages
•  Signs can be broken down into segmental
features similar to the phonetic features of
speech sounds (such as place and manner of
articulation)
–  And just like spoken languages, signed languages of
the world vary in these features
–  Signs are formed by three major features:
•  1. The configuration of the hand (handshape)
•  2. The movement of the hand and arm towards or away from
the body
•  3. The location of the hand in signing space

Phonetics of Signed Languages
•  The configuration of the hand (handshape)
•  The movement of the hand and arm
•  The location of the hand in signing space
