Study Notes

Pulmonic Egressive Air Stream Mechanism

  • The shape of the glottis determines the type of sound produced:
    • Open glottis: neutral state in normal breathing, producing voiceless sounds
    • Narrow glottis: producing voiced sounds
    • Closed glottis: producing a glottal stop

Plosives (Oral Stops)

  • Defined by complete closure in the vocal tract
  • Examples: pie, buy, die, tie, kill, goal
  • Cannot be made into a long sound (e.g., "k" cannot be sustained)

Nasal Stops

  • Defined by complete closure in the vocal tract, but in the nasal cavity
  • Examples: my, night, sing
  • Considered stops (non-continuants), but not plosives

Fricatives

  • Air escapes through the mouth
  • Examples: see, zoo, ship, think
  • Include sounds [s, z, %, &, !, ", f, v, h]

Other Stop Sounds

  • Taps or flaps: quick, ballistic movement of the tongue
  • Examples: water, butter, letter (in General American, /t/ is realized as [ɾ] or [tÌ­])
  • Trills: repeated taps, as in "the rolling r" (Frankonian, Bavarian, etc.)

Approximants

  • Continuant sounds, but air stream can escape the mouth without friction
  • Examples: glides [w, j] (also known as semi-vowels), liquids [r, l] (rhotic liquid and lateral liquid)

Note about /r/

  • Several different realizations across English varieties and positions within the same dialect
  • Examples: [ɹ] (alveolar approximant, RP), [É»] (retroflex approximant, GA)

Lateral Consonant

  • Oral airflow is central for all sounds in English except for /l/ (realized as [l] or [#])
  • /l/ is lateral, with air flowing around the tongue
  • This feature is most useful to distinguish among liquids (i.e., /l/ from /r/)

Sonorant Sounds

  • Include nasal sounds, liquids, and glides
  • Characterized by spontaneous voicing, greater openness of the channel, and carrying a greater amount of sound
  • All vowels are sonorant

Obstruents (Non-Sonorant)

  • Constriction inhibits airflow, causing supraglottal pressure to rise
  • Voicing is prohibited unless special measures are taken to keep it going
