Phonetics
1
Objectives:• Explore the relationship between sound
and spelling• Become familiar with International
Phonetic Alphabet (IPA )• Understand the nature of consonants and
vowels• Learn where particular sounds occur
(physical aspects of the human vocal tract)• How sounds change when different sounds
surround them• Yule: Chapter 3, The Sounds of Language

Phonetics Acoustic phonetics – the
physical properties of speech as sound waves in the air
Auditory phonetics – the study of the perception of speech sounds, via the ear
Articulatory phonetics – the study of how speech sounds are made, or ‘articulated’
3
Articulatory Phonetics Deals with the way in which speech
sounds are produced, what parts of the mouth and in what sorts of configurations
Phoneticians’ techniques – x-ray photography, palatography (to observe contact btwn the tongue and the roof of the mouth)
Most basic tool – impressionistic phonetic transcription: e.g. tomato Webster’s: tə-mā-tō tə-mä-tō Gershwin: tomato tomahto

CHEF?
sure dead laugh
Imagine a word spelled as
But pronounced as
How would one come to this spelling?
Describing Language Sounds
• The sounds of spoken English often do not match up with the letters of written English.
• One solution to describe the sounds of a language is to produce a separate alphabet with symbols that represent sound phonetic alphabet
• These symbols represent both the consonant and vowel sounds of language
6
A “Good” Phonetic Alphabet: Characteristics
1. Each symbol should represent only one sound (phone)– e.g. <c>: [k] in cat and [s] in cymbal
2. If 2 sounds can distinguish one word from another, they should be represented by different symbols– e.g. <th>: they vs. thigh
Good phonetic transcription unambiguously convey the important aspects of the pronunciation of a given set of sounds, using a written system of symbols.
7
A “Good” Phonetic Alphabet: Characteristics
3. If 2 sounds are very similar and their differences arise only from the context they’re in, those similarities should be represented
[k] sounds in keep and cool (place where they’re articulated are dependent on the following vowel)
8
The English Alphabet The English alphabet has 26
letters but there are over 40 different speech sounds:
5 vowel and 21 consonant letters of the alphabet
About 20 vowel sounds and 24 consonant sounds (depending on dialect)
9
A “Good” Phonetic Alphabet: Not English
Same sound spelled using different letters: sea, see, scene, receive, thief, amoeba, machine
Same letters can stand for different sounds: - sign, pleasure, resign
- dough, through, rough, cough, fought, drought
10
A “Good” Phonetic Alphabet: Not English
Single sound spelled by a combination of letters: lock, that, book
Single letter represents a combination of sounds: exit, use
Sometimes letters stand for no sound at all: know, doubt, though
11
Transcription
the conversion of spoken words into written words
the process of matching the sounds of human speech to special written symbols
using a set of exact rules, so that these sounds can be reproduced later.

Transcription
• There are two kinds of transcription– Narrow transcription:
– seeks to document every possible detail of the segment–very often, these details are not
discernible to the native speaker– Broad transcription:
– specifies the segments that are contrastive in the language– far fewer sounds are documented
13
Transcription
• A transcription system for these purposes must be different from traditional writing systems– Some features of a good phonetic transcription
system:– Universal: no preference given to any existing
spelling system– Interpretable: other linguists should be able to
interpret it– Transparent: one-to-one correspondence between
sounds and symbols– Comprehensive: symbols for all the sounds in
human language– The International Phonetic Alphabet (IPA) is the
best attempt so far (chart uploaded in Bb)

English Sounds
16
• All English words are made from combinations of consonants and vowels
• Every English segment can be uniquely described in three or four words• [p] is the voiceless (bi-)labial (oral) stop• [e] is the upper-mid front vowel• [n] is the alveolar nasal (stop)
Voiced and Voiceless Sounds Inside the larynx are the vocal cords One position: voiceless
Vocal cords are open, the air from the lungs passes between them unimpeded. e.g. /s/
Another position: voiced When the vocal cords are drawn
together, the air from the lungs repeatedly pushes them apart as it passes through, creating a vibration effect. e.g. /z/
17
Consonants
• Consonants are generally produced with greater constriction within the vocal tract.
• Description of consonants– Voicing: describes the state of the
larynx– Place of Articulation: describes the
location of the obstruction or constriction – Manner of Articulation: describes the
type of constriction and the passage of airflow
– e.g. /s/ voiceless alveolar fricative18

English Sounds: Vowels
22
• Exercise: Hold your jaw lightly, now say he, who, and ha. Did your jaw move for ha?
• Vowels don’t have a consonant-like point of articulation or manner of articulation. The three standard descriptors for consonants (place, manner, voicing) aren’t helpful when we want to describe vowels.
English Sounds: Vowels
23
• There are 4 main ways in which speakers can change the shape of the vocal tract and thus change vowel quality. Raising of lowering the body of the tongue Advancing or retracting the body of the tongue Rounding or not rounding the lips A tense or lax gesture of the tongue body
• Manner: all vowels are articulated in the same way, with the tongue raising or lowering to the target position
• All vowels (in English) are voiced
IPA VowelsYule, pg.34
24
Vowel Space(Height x Backness Space)
The space is typically quadrilateral in shape. (quadra = four; lateral = side)
It is also (and primarily) an auditory space.
We hear vowels as similar or different from each other depending on their proximity in this space. 25
Monophthongs of English
26
seat
set
sat
You will find that you open your mouth a little wider as you change from [i] to [Ɛ] to [æ]
These varying degrees of openness correspond to different degrees of tongue height
Monophthongs of English
27
Made with the front of the mouth less open because the tongue body is raised, or high
Produced with an
intermediate tongue
height
Pronounced with the
front of the mouth
open and the
tongue lowered.
Monophthongs of English
28
beat boot
Beat: the body of the tongue is raised and pushed forward so it’s just under the hard palate.
Boot: made by raising the body of the tongue in the back of the mouth, toward the velum
Monophthongs of English
29
Front: tongue is moved forward or advanced for all front monophthongs
Back: tongue is retracted or pulled back for the back monophthongs
Lip Rounding
Vowel quality also depends on lip position
[u] in two lips are rounded
[i] in tea lips are unrounded
30
31
Diphthongs: Complex vowel sounds because they are two-part vowel sounds, consisting of a transition from one vowel to the other in the same syllable
Try saying eye very slowly. How do you make this vowel sound?
1. Your tongue starts out in the low back position for [α]
2. Then your tongue moves toward the front position for [I]
