Phonemes

  • Distribution of Phonemes
    • most have a wide ranging distribution (t)
    • some languages have phonemes w/ limited or defective distributions
    • h: only at beginning of syllables
    • ŋ: only at end of syllables
    • specific notation: the phoneme is pronounced as the allophone in the environment
  • Conditioning Environments: causes allophony
    • Positional: different allophones can occur depending on where it is in the word (ex: f) [initial, medial, final]
    • Adjacent Segments / Assimilation: sounds frequently assimilate to neighboring sounds (ex: nasalization)
    • Stress: both vowels and consonants can have different allophones in stressed v unstressed syllables
  • Some Phonological Processes
    • Voicing Assimilation: voiceless speech sounds get voiced when they neighbor other voiced sounds
    • Devoicing: voiced segments become devoiced at the very end of words as the vibration of vocal folds stops prematurely. b, d, g ➝ p, t, k
    • Place Assimilation: vowels and consonants take on the place of articulation of a neighboring sound
    • Palatalization: a shift to a more palatal place of articulation
  • A Brief Overview of Theory
    • mental representations of the sound shape of words are stored as phonemes in the Lexicon
    • allophones activate the same specific area of the brain as phonemes
    • phonological rules: formal statements of what occurred in speech
    • nasalization, place assimilation, aspiration
  • How to do a phoneme analysis
    • Question the phonetics of sounds involved. Should be phonetically similar
    • Analyze the sound’s distribution and where each sound occurs
    • by position: initial, medial, and final
    • by adjacent segments
    • Determine the phonological relationship
    • Contrast: minimal and subminimal pairs
    • Complementary: non-overlapping environments
