      Phonetics:
The Sounds of Language
              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
    The Phonetic Alphabet
– 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
    The Phonetic Alphabet
– 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
      The Phonetic Alphabet
• 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
       The Phonetic Alphabet
• Dialectal and individual differences affect
  pronunciation, but the sounds of English
  are:
      The Phonetic Alphabet
• 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 Articulation
                           © Cengage Learning
  Consonants: Place of Articulation
• Bilabials: [p] [b] [m]
   – Produced by bringing both lips together
• Labiodentals: [f] [v]
   – Produced by touching the bottom lip to the upper teeth
• Interdentals [θ] [ð]
   – Produced by putting the tip of the tongue between the
     teeth
  Consonants: Place of Articulation
• 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
  Consonants: Place of Articulation
• 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 soft palate or velum
• Uvulars: [ʀ] [q] [ɢ]
    – Produced by raising the back of the tongue to the uvula
• Glottals: [h] [Ɂ]
    – Produced by restricting the airflow through the open glottis ([h]) or by
      stopping the air completely at the glottis (a glottal 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 Articulation
• The voiced/voiceless distinction is important in
  English because it helps us distinguish words like:
     rope/robe           fine/vine      seal/zeal
     [rop]/[rob]   [faɪn]/[vaɪn]  [sil]/[zil]
• But some voiceless sounds can be further
  distinguished 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 Articulation
• 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 fraction of a second
       • All other sounds are continuants, meaning that the
         airflow is continuous through the oral cavity
• Fricatives: [f] [v] [θ] [ð] [s] [z] [ʃ] [ʒ] [x] [ɣ] [h]
   – Produced by severely obstructing the airflow so as
     to cause friction
  Consonants: Manner of Articulation
• Affricates: [ʧ] [ʤ]
   – Produced by a stop closure that is released with a lot of
     friction
• Liquids: [l] [r]
   – Produced by causing some obstruction of the airstream in
     the mouth, but not enough to cause any real friction
• Glides: [j] [w]
   – Produced with very little obstruction of the airstream and
     are always followed by a vowel
        Consonants: Manner of Articulation
    •   Approximants: [w] [j] [r] [l]
         – Sometimes liquids and glides are put together into one category because the
           articulators approximate a frictional closeness but do not actually cause
           friction
    •   Trills and flaps: [r]* [ɾ]
         – Trills are produced by rapidly vibrating an articulator
         – Flaps are produced by a flick of the tongue against the alveolar ridge
    •   Clicks:
         – Produced by moving air in the mouth between various articulators
         – 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
© Cengage Learning
                                  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)
•   Nasalization:
     – 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 nasalization is represented by a diacritic, 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
Vowels
        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 Phonetic Classes: Consonantal
• Consonantal: there is some restriction of the airflow
  during articulation
   – All consonants except glides
• Consonantal sounds can be further subdivided:
   – Labials: [p] [b] [m] [f] [v] [w] [ʍ]
       • Articulated with the lips
   – Coronals: [θ] [ð] [t] [d] [n] [s] [z] [ʃ] [ʒ] [ʧ][ʤ] [l] [r]
       • Articulated by raising the tongue blade
            Major Phonetic 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 friction that causes a hissing sound, which is
         a mixture of high-frequency sounds
• Syllabic Sounds: sounds that can function 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
  articulation
• 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 Intonation
• 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
