Session 1: Basics of English phonetics
English B level course: Phonetics spring 2015
Larisa O.-Gustafsson
Speech sounds and letters of the Present-day English language
43 (39) speech sounds (phonemes)
26 letters of the English alphabet
As a result: inconsistency in spelling, a special need for transcription
signs and pronunciation dictionaries for language learners
e.g. bough – cough – enough – though – through
The digraph ou represents 5 different speech sounds (phonemes)
Phonetics and phonologystudy the sound systems of languages … . While
phonetics studies ALL possible sounds that the
human vocal apparatus can make, phonology
studies only those contrasts in sound which
make differences in meaning within language.
Examples of phonemic contrasts:thin / tin /sin, think /sink = minimal pairs (word pairs that differ only in one phoneme)
Types of phonetic studies
Articulatory phonetics = the study of how speech sounds are made (articulated)
Acoustic phonetics = the study of the physical
properties of speech as sound waves
Auditory phonetics = the study of the perception of speech sounds
Phoneme – Phone – Allophone: the case of /l/
Let a million people have milk
/l/ is articulated in different ways in these
words, but all these versions belong
together in ONE English phoneme. They are
allophones (dark and clear, or light /l/) of
that phoneme.
Phoneme – Phone – Allophone
Phoneme = a basic unit of which words are composed. It functions contrastively and is an abstract unit, a sound-type ”in the mind”
Phones are all the different versions of a phoneme produced in actual speech
Allophones are a set of phones, all of which are versions of a single phoneme
Classification of phonemesThe articulatory classification
Consonants are articulated via obstruction in vocal tract. Tongue and
other parts of mouth constrict shape of oral cavity through which air is passing.
Vowels are produced by a relatively free flow of air. Tongue influances shape
through which air passes, which results in different vowel sounds. Vowels tend to
be more unstable and variable, and change more rapidly over time.
Classification of consonants: 1
Position of vocal cords cords drawn together: voiced (bill, that, van,
den, business) cords lie open: voiceless (pill, math, fan, ten,
business)
Place of articulation lips: bilabial (bill/pill) teeth: dental (that/math) lips & teeth: labio-dental (van/fan) teethridge: alveolar (den/ten, not, business)
Consonant classification: 2
Manner of articulation = describes how the tongue, jaw, and other organs of speech are involved in a sound make contact
stops or plosives: oral (pen) and nasal (pen)fricatives or sibilants (van, fan)affricates (nature, grudge)liguids (red /non-rotic/, led) glides or semi-vowels (wait, yellow)rotics (Am right)
Three parameters of consonant classification: VPM
V (voice) – P (place) – M (manner)
/p/ voiceless bilabial plosive/l/ voiced alveolar lateral/m/ voiced bilabial nasal/f/ voiceless labio-dental fricative
Grimm’s Law or the First Germanic Sound Shift
Aspirated voiced stops Voiced stops Voiceless stops Voiceless fricatives

Vowel classification
front vowels: key, bid, said, bad
central vowels: above, blood
back vowels: move, book, fall, swan
Diphthongs = a combination of two vowel sounds in which the vocal cords move form one position to another: e.g. tie, toy, town
Speech sounds are modified to simplify the articulation, usu in untressed syllables, rapid tempo, and informal style
Assimilation = adjustment to surrounding sounds won’t come, down by law, Great Britain
Elision = the use of schwa or reduction of sounds in unstressed syllables natural, differ, camera listen, answer (historical elision)
Speech sounds in connected speech: coarticulation effects
Front Mutation (i-umlaut)
Regressive distant assimilation = a
change of a back vowel to the associated front vowel or
or a front vowel becomes closer to /j/ when the following
syllable contains /i/, /iː/, or /j/
