Fundamentals of English Phonetics and Phonology

1. Key Concepts

  • Phonetics: The physical study of speech sounds (production, transmission, perception).
    Example: Studying how /p/ is produced with the lips.
  • Phonology: The study of how sounds function in a language system.
    Example: /p/ vs /b/ distinguishes meaning in pat vs bat.
  • Grapheme: A written symbol representing a sound.
    Example: The grapheme “sh” represents the sound /ʃ/ in ship.
  • Phoneme: The smallest sound unit that changes meaning.
    Example: /ɪ/ vs /iː/ in ship (/ʃɪp/) vs sheep (/ʃiːp/).
  • Allophone: A variant of the same phoneme that does not change meaning.
    Example: Aspirated [pʰ] in pin and unaspirated [p] in spin.

2. Types of Phonetics

  • Articulatory phonetics: How sounds are produced.
    Example: Describing how the tongue touches the alveolar ridge for /t/.
  • Acoustic phonetics: Physical properties of sounds (frequency, intensity, duration).
    Example: Measuring the frequency of a vowel sound.
  • Auditory phonetics: How sounds are perceived.
    Example: How listeners distinguish /s/ from /ʃ/.

3. Speech Production: The Airstream Mechanism

  • Pulmonic egressive airstream: Air flows outward from the lungs.
    Example: Most English sounds such as /s/ and /k/.

Three Systems

  1. Respiratory system: Lungs provide air.
    Example: Controlled breathing while speaking.
  2. Phonatory system: Vocal folds vibrate or not.
    Example: /z/ is voiced, /s/ is voiceless.
  3. Articulatory system: Organs shape the sound.
    Example: Lips produce /p/ and /b/.

4. Consonant Classification

  • Voicing: Voiced vs. voiceless.
    Example: /b/ (voiced) vs /p/ (voiceless).
  • Place of articulation: Where the sound is produced.
    Example: /m/ is bilabial (two lips).
  • Manner of articulation: How the air flows.
    Example: /f/ is a fricative (air passes with friction).

5. Vowels

Described by:

  • Tongue height: Close vs. open.
    Example: /iː/ in see is close.
  • Tongue position: Front, central, or back.
    Example: /uː/ in food is back.
  • Lip rounding: Rounded vs. unrounded.
    Example: /uː/ is rounded.
  • Length: Long vs. short.
    Example: /ɪ/ in sit vs /iː/ in seat.

Types

  • Monophthong: Single vowel sound.
    Example: /æ/ in cat.
  • Diphthong: Vowel glide.
    Example: /aɪ/ in time.

6. IPA and Transcription

  • IPA (International Phonetic Alphabet): Universal system for writing sounds.
    Example: cat → /kæt/
  • Phonemic transcription (/ /): Shows phonemes only.
    Example: /kæt/
  • Phonetic transcription ([ ]): Shows detailed pronunciation.
    Example: [kʰæt]

7. Syllable Structure

  • Syllable: A vowel nucleus with optional consonants.
    Example: cat = /k/ onset + /æ/ nucleus + /t/ coda.
  • Open syllable: Ends in a vowel.
    Example: go (/ɡəʊ/).
  • Closed syllable: Ends in a consonant.
    Example: dog (/dɒɡ/).

8. Stress

  • Word stress: Stressed syllable in a word.
    Example: aˈbout.
  • Sentence stress: Stressed words in a sentence.
    Example: I bought a NEW CAR.
  • Content words: Nouns, verbs, adjectives (usually stressed).
    Example: house, run.
  • Function words: Prepositions, articles (usually unstressed).
    Example: of, the.

9. Morpheme Pronunciation

  • -ed
    • /t/ → worked
    • /d/ → played
    • /ɪd/ → wanted
  • -s
    • /s/ → cats
    • /z/ → dogs
    • /ɪz/ → buses

10. Connected Speech Processes

  • Assimilation: Sound changes to become similar.
    Example: handbag → /ˈhæmbæɡ/
  • Elision: Sound omission.
    Example: next day → /neks deɪ/
  • Linking: Connecting sounds between words.
    Example: far away → /fɑːr əˈweɪ/

11. RP vs. GA

  • RP (Received Pronunciation): Non-rhotic (r not pronounced at the end).
    Example: car /kɑː/
  • GA (General American): Rhotic (r pronounced).
    Example: car /kɑr/
