Ling2002 Flashcards
Phonetics:
About the physical nature of speech sounds, their production and physical properties (articulation, acoustic properties, perceptual properties).
Phonology:
About the way that languages use/organise these sounds to encode meaning. I.e. how differences in sound are used to differentiate words in a language. How sounds are sequences within words, etc.
Articulatory phonetics:
The study of the organs of speech and their use in producing speech sounds.
Acoustic phonetics:
The study of the physical properties of sounds produced in speaking.
Auditory/perceptual phonetics:
The study of the perception of speech sounds by the ear, nervous system and brain.
Articulatory undershoot:
In normal speech, the the articulators frequently do not meet their (presumed) articulatory targets.
Articulatory undershoot may vary according to:
- The style of speed of speaking. E.g. ‘g’ in ‘recognition’ completely stops airflow in careful pronunciation; allows airflow in casual.
- Physical and emotional state.
- The phonetic targets of neighbouring sounds.
Co-articulation:
Transition between targets can result in an incidental simultaneous articulation which is not a specific phonetic target.
Co-ordination between the two constrictions:
- (Near-)simultaneous: both targets at the same time
- Sequential: one after the other
- Simultaneous onset, sequential release: articulators form two constrictions, one released just before the other (clicks, ejectives, implosives).
Passive articulators:
Articulators that do not move.
Apico-
Top of tongue
Lamino-
Blade of tongue
Egressive airstream:
flowing outwards (of the vocal tract)
Ingressive airstream:
flowing inwards (of the vocal tract). Sounds like clicks and implosives.
Pulmonic airstream:
airstream produced by action of the lungs. This is the majority of speech sounds.
Glottalic aistream:
airstream produced by movement of the (closed) glottis. Implosives (ingressive) and ejectives (egressive).
Velaric airstream:
airstream produced by the action of the tongue. Clicks (ingressive).
Voiced sounds:
The edges of the folds are held loosely together in such a way that air under pressure from the lungs can pass between the folds only in very small bursts
Voiceless sounds:
The folds are held relatively wide apart and the airstream passes through relatively undisturbed.
Whispering:
The folds are held closely together to create a narrow opening through which a high energy airstream is forced.
Creaky voice:
Results when the rear of the vocal folds are held tightly together but air is allowed to pass through the front of the glottis in small bursts.
Murmer:
The folds are held apart but the rate of airflow is so high that the folds ‘flap in the breeze’
Voice Onset Time (VOT):
The interval in the production of an individual consonant phone between the release of the supra-glottal constriction (e.g. at the lips) and, the (re-)start of the voicing for the following vowel.
Strong aspirated:
Large positive VOT, > 50ms.
Unaspirated voiceless:
Zero VOT
Fully voiced:
Negative VOT (or not measured)
Partially voiced
Negative VOT
Lower F1:
Tongue higher
