Chapter 2: Consonants and Vowels

1. Spoken vs. Written Language

  • Speech and writing are distinct media; speech predates writing historically.

  • Writing can inadequately represent speech (e.g., English spelling issues):

    • One sound can have multiple spellings (e.g., "meat", "meet").

    • One letter can represent multiple sounds (e.g., "d" in "damage", "educate").

    • Sounds may lack graphic representation (e.g., initial sounds in "universe").

2. Production of Speech Sounds

  • Speech sounds produced via respiratory system; primarily egressive pulmonic sounds.

  • Involve air expulsion from lungs through the larynx, creating sounds through vocal cord vibration.

  • Articulators (e.g., tongue, lips) define sound formation, contributing to consonants and vowels.

3. Consonant Sounds

3.1 Definition and Classification of Consonants

  • Consonants involve stricture of the air stream, differing from vowels (which are open).

  • Classified based on:

    • State of the glottis (voiced vs. voiceless).

    • State of the velum (raised vs. lowered).

    • Place of articulation (e.g., bilabial, alveolar, velar).

    • Manner of articulation (e.g., stops, fricatives).

3.2 English Consonants

  • English consonant inventory includes:

    • Stops: /p/, /b/, /t/, /d/, /k/, /g/

    • Nasals: /m/, /n/, /ŋ/

    • Fricatives: /f/, /v/, /θ/, /ð/, /s/, /z/, /ʃ/, /ʒ/

    • Affricates: /tʃ/, /dʒ/

    • Approximants: /l/, /r/, /j/, /w/

    • Patterns of voicing and articulation vary within the system.

4. Vowel Sounds

4.1 Definition and Characteristics

  • Vowels are produced with open airflow and form the nucleus of syllables.

  • Classifiable by:

    • Tongue height and position (e.g., front, back).

    • Tension and lip rounding.

    • Duration, represented as monophthongs or diphthongs.

4.2 English Vowel Inventory

  • Includes monophthongs like /i/, /æ/, /ʌ/, /u/, and diphthongs (e.g. /aɪ/, /eɪ/).

  • Tensions and qualities are crucial for proper articulation and comprehension.

5. Function of Vowels and Consonants

  • Vowels usually serve as syllabic nuclei, are louder and longer than consonants.

  • Consonants often have a nonsyllabic function, contributing to syllable structure without being obligatory.

  • Some consonants can act as syllabic, particularly nasals and liquids in forms without vowels (e.g., "bottle").

Commentary

  • Phonetics encompasses articulatory, auditory, and acoustic segments.

  • Understanding the sound systems enhances perception and articulation in language.

  • Each phonetic element influences communication, literacy, and language development, necessitating clear differentiation of speech patterns.
