Lecture 1


Phonetics and phonology
Phonetics and Phonology

  • Phonetics: The physical manifestation of language in sound waves.

    • How sounds are articulated

    • How sounds are perceived

  • Phonology: The mental representation of sounds.

    Example:





Sounds categorization
Sounds Categorization

  • Manner of articulation

    closure made by the articulators and the degree of the obstruction of the air stream by those articulators.

  • Place of articulation

    Position of the articulators e-g: tongue, lips etc.

  • Status of glottis

    Voicing : vocal cords are vibrating

    Voiceless: vocal cords do not vibrate


Sound categorization
Sound Categorization

  • A good link to understand manner and place of articulation (only sounds in American English).
