Phonetics 1: Articulation

Vocabulary flashcards based on the lecture notes about phonetics.

Phonetics

The study of speech sounds.

Three A's of phonetics

• Articulatory

• Acoustic

• Auditory

Articulatory Phonetics

the production of speech sounds.

Acoustic Phonetics

how we hear speech sounds

Auditory Phonetics

the perception of speech sounds.

Phases of Speech Production

• Initiation

• Phonation

• Articulation

Initiation

The lungs produce an air pressure by inhaling, which is then expelled through throat and mouth or nose. (Pulmonic egressive air stream)

Phonation

The air stream passes through the larynx and sets the vocal folds/cords in motion. This vibration produces the actual voice. (voiced vs. voiceless sounds)

Articulation

The oscillating air stream passes through pharynx, the mouth or nose and is then modified by articulating speech organs (articulators: e.g. tongue, palate, teeth, lips)

Pulmonic egressive airstream(initiation)

Airflow produced by exhaling, used in speech production.

Glottis

The opening between the vocal folds.

Homorganic

Sounds that share a place of articulation.

passive articulator

 Palate

 Alveolar ridge

 teeth

Active Articulator

Term describing the tongue and lips.

Manner of Articulation

The different ways of obstructing the airstream.

Three Major Articulatory Configurations

 Sustained contact (complete closure) ≈ closed door

 Close approximation ≈ hedge

 Open approximation ≈ open door

Representation of Plosives

Major Articulatory Configurations

 Sustained contact (complete closure): plosives (nasals if there is no velic

closure)

 Close approximation: fricatives

 Open approximation: median and lateral approximants

Trill/Tap

A sound produced by momentary contact between active and passive articulators.
