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), [ɻ] (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
