Phonetics & Phonology
General considerations
   Speech sounds and sounds that convey
    meaning
   Their patterns
   Sound change
Phonetics
The study of how speech sounds are made,
transmitted and received
Vocal organs
   The lungs and windpipe/trachea
   Larynx and vocal cords
   Vocal tract/cavity: oral tract vs. nasal tract
   Upper lip/teeth, alveolar ridge, hard/soft palate,
    uvular and pharynx
   Lower lip/teeth and the tip/blade/front/center/
    back/root of the tongue
Consonants
Airstream being obstructed in some way
   Voicing
   Places of articulation
   Manners of articulation

Compare: vie, phi, buy, my
Places of articulation
 bilabial: pie/buy/my
 labiodental: five/vie

 dental: thigh/thy

 alveolar: tie/die/nigh/sigh/zeal/lie

 retroflex: rye

 palato-alveolar: shy

 palatal: you

 velar: hack/hag/hang

Compare: fee, theme, see, she
            wing, win, whim
Manners of articulation
   plosive: my/nigh vs. pie/tie/guy        (nasal vs. oral)
   frictive: five/vie/sigh/zoo/thigh/thy/shy
   approximant: yacht/we/raw
   lateral: lay/ale
   affricate: church/judge

[s] in sing: voiceless, alveolar frictive
[N] in sing: voiced, velar, nasal stop
Vowels
   The height of the body of the tongue
   The front-back position of the tongue
   The degree of lip rounding
Assimilation
   Regressive
    right place       [p]
    good morning      [b]
    one cup cf bank   [N]
    have to           [f]
   Progressive
    cats              [s]
    dogs              [z]
CV continuum & syllabics

         More/less vowel/consonant-like

Vowels                             Consonants
                    [m][n][l]

button     [bQtn]
Little     [litl]
Weak forms
black and white     [En]
but why not         [bEt]
as good as gold     [Ez]
better than not     [TEn]
Did he win          [i]
How do they know    [dE] (before consonants)
to stay or to go    [tE]
I need some paper   [sEm]
The men have gone   [Ev] (not after pronouns)
Suprasegmentals
   Stress (and rhythm)
    It was an accident.
    cheaper fares – cheap affairs
    Give it to John.
    How did you manage to be there in time?
   Pitch/Intonation
    He was in an appalling bad temper.
   Length: bed – beat    cf big – wish
Phonology
   which sounds occur
    e.g. *xoda - poda
   what their distribution is
    e.g. *ngatus – singer/sing
   how they can be combined
    e.g. *bnick - blick
   how they might be realized differently in different
    positions
    e.g blocks – boards - mattresses
Properties of phonology
   Abstract
   Universal
   Modular
   Hierarchical
e.g. 1a. electric – electricity
               [k]        [s]
      b. kick −/→ sick
     2a. cats – dogs – matches
      b. Abner
Phones, minimal pair, phonemes
and allophones
              (allo)phones    phonemes
meat – neat    [m,n]           /m,n/
buy – pie      [b,ph]          /b,p/
pie – spy      [ph,p]


Phonological rules: a   b / c_d
e.g. ph p / s_
Grouping sounds into phonemes
   Complementary distribution
   Free variation
   Phonetic similarity
    e.g. shoe - she
         cup
