Midterm prep ling Flashcards
The IPA
International phonetic alphabet, used for transcription
- 1 symbol for every sound used distinctively in 1+ languages
Airstream mechanisms
expelled = egressive inhaled = ingressive
larynx
Modulates airflow, acts as a valve
- The vocal chords
- Cartillage, muscles, tissue
Vocal tract
pharynx, oral & nasal cavity
- Filters ot modify sound
Glottis
Space between folds where air passes
Voiceless
Folds apart
- No vibration
- Sound produced = voiceless
e. g. [s], [f], [h]
Voiced
Folds together
- Air passes = vibration
- Fold vibration rate = different pitches
e. g. [z], [v]
Breathy
Folds partially open
- Vibration
- In English = different voices, not sounds
Creaky
Folds compressed and slack
- Vibrates slowly + irregularly = lower pitch
- Used to distinguish end of utterance, not sounds
Why vocal organs?
-Larynx descended lower in humans than other primates for speech
Advantage: Tongue can produce wider range of sound
Disadvantage: Easier to choke
Vowels described articulatory, Aerodynamically and by sound class (acoustic)
Artic. : Open vocal tract
Aero: Laminal (direct air flow)
Class: More acoustic energy
Consonants described particularly, Aerodynamically and by sound class (acoustic)
Artic. : Closed vocal tract
Aero: No/turbulent air flow
Class: Less acoustic energy, intervals of silence
Stops/plosives
Build up then release of pressure
- Followed by burst of air = aspiration
e. g. [p] “spin”
Fricative
Small opening, turbulent flow
Affricate
Stop with slow release
- Transcribed as stop + fricative using tie bar
e. g. “raTCHet”
Sibilant affricates and fricatives
Stridents
- Noisy
- Airstream goes through narrow channel + hits teeth
Non-sibilant affricates and fricatives
Quieter than sibilants, e.g. “th”
Obstruents
Stops, fricatives, affricates
- Obstructed airflow
- Turbulent = noise
Opposite = Sonorants
Sonorants
Liquids, approximates, glides, nasals, vowels
- Non-turbulent
- More sonorous
Opposite = Obstruents
*Nasals, liquids and glides can be syllabic
Approximates
Liquids and glides
- Liquids: change [r l] without constriction
- Glides: Short, non-syllabic vowels such as [j w]
e. g. laterals - direct air flow around sides of tongue
