Title: Phonetics


1
Phonetics Phonology of EnglishHow Why We
Speak the Way We Do
  • Dr. Latricia Trites
  • Academic Advisor
  • Fulbright Yilan Project 2008-2009

2
What is Phonetics?
  • Phonetics is the study of speech sounds.
  • Articulatory phonetics how speech sounds are
    produced
  • Acoustic phonetics the transmission and
    physical properties of speech sounds
  • Auditory phonetics perception of speech sounds
  • Phonetic transcriptions one sound one symbol.

3
Consonants
  • The descriptions of the sounds we call consonants
    are based on the human articulatory system (lungs
    to pump air in and out, vocal folds, oral cavity
    including tongue and lips, and nasal cavity).
  • Consonants are described using 3 characteristics
  • vocal quality (voiced/voiceless)
  • point of articulation
  • manner of articulation

4
  • The Articulators

5
  • Places of articulation (for consonants)

Vowels
  • Place of articulation, manner of articulation and
    voicing are not useful when trying to describe
    vowels.
  • Vowels are all made in the mouth (place), with
    little or no air flow constriction (manner) and
    are always voiced in English
  • So the system that describes vowels does so in
    terms 4 characteristics
  • tongue placement
  • tongue height
  • lip rounding
  • tenseness.

10
Suprasegmentals! What are those?
  • Length
  • High vowels shorter than low vowels
  • Voiceless consonants longer than voiced
    consonants
  • Voiceless fricatives longest
  • Length is influenced by the surrounding sounds
  • Tone
  • Can change meaning in some languages (like
    Chinese)
  • Stress
  • Stressed syllables more prominent than unstressed
    ones
  • Stressed syllables usually contain tense vowels
  • Stressed syllables are often longer
  • Unstressed syllables reduce vowel
  • Intonation
  • Rising and falling intonation can change meaning

11
What is Phonology?
  • Phonology is how speech sounds are organized and
    affect one another in pronunciation.
  • Key terms
  • Phone sound that is actually heard
  • Phoneme more theoretical (idea) of a sound / /
  • Allophone nondistinctive realization of the
    same phoneme
  • This organization is explained in phonological
    rules

12
Different Types of Phonological Variation
  • Overlapping Distribution different sound in
    same environment (ex. /thap/ vs. /phat/).
  • Contrastive distribution changing sound changes
    meaning (ex. /mæn/ vs./m?n/).
  • Complementary distribution sounds in a language
    never found in the same phonetic environment (ex.
    /thap/ vs. /path/).
  • Free variation two sounds that occur in
    overlapping environments but doesnt change
    meaning (ex. /?np?t/ vs. / ?mp?t /).

Italics indicates sound variant that cannot
occur in the English language

Common Phonemic Rules
  • Aspiration h

  • Flap ?
  • Dental Consonants ?
  • Velarization ?
  • Voicelessness
  • Vowel lengthening ?
  • Vowel nasalization

14
Phonemic Rules
  • Aspiration Rule Voiceless stops are aspirated at
    the beginning of a stressed syllable.
  • Liquid/Glide Devoicing Liquids/Glides become
    voiceless when they follow a voiceless stop,
    fricative, or affricate.
  • Vowel Lengthening Vowels are lengthened when
    they come before a voiced consonant.
  • Flapping When a /t/ or /d/ is preceded by a
    vowel and followed by a vowel, it becomes flapped
    (ex. bitter, butter, batter, ladder, letter,
    beauty, beautiful).

15
Common Phonological Rules
  • Assimilation becomes like the neighboring sound
    (ex. hippo)
  • Palatization (ex. Dont you, Wont you)
  • r coloring (ex. fur, bird, party) often seen as
    /?/or/?/
  • Nasal coloring
  • Dissimilation (ex. fifth, sixth)
  • Insertion (ex. dance, strength, hamster)
  • Deletion (ex. chocolate, interesting)

16
Important Information to Remember
  1. There are EXCEPTIONS to every rule in English.
  2. English speakers, like all other languages try to
    say things as quickly and easily as possible.
  3. Every region and dialect will have variations in
    speech patterns however, it is important to
    foster correct pronunciation instead of bad
    habits.

17
Tips
  • Be consistent with one symbol one sound.
  • Remember that bo po mo fo is used to teach
    Mandarin, not English, because the language is
    built on syllables, English is a sound/symbol
    language, not built on syllables.
  • Help students understand how sounds are made.
  • Help students learn to sound out words instead of
    just listen and repeat.
  • Be aware of common mistakes based on first
    language that students tend to make dropping
    final consonants, confusing /l/ and /r/,
    inserting /?/, pronouncing all vowels as tense
    vowels.
  • Remember that there are useful websites where you
    can find correct pronunciation of English words.

18
Teaching Phonics
  • How can we use this phonetic information and the
    phonological rules to teach phonics better?
  • Using your regular textbook, take 10 - 15 minutes
    to design a phonics activity that incorporates
    some of the information learned today.
