Phonetics Flashcards
Approaches to the study of phonetics
perception, production, instrumental, developmental, cultural, historical
graphemes
written symbols; a unit in the writing system of a language
phonemes
speech sounds; the smallest and most basic speech segment that has the function of distinguishing morphemes
morphemes
the smallest unit of a language that carries meaning
orthography
the conventional system of written spelling used in a language
isomorphism
a one-to-one correspondence between the members of two sets; there is no isomorphism between sounds and symbols in written English
what are the 3 systems of speech production?
supralaryngeal, laryngeal, respirator
respiratory system function in speech
inhale, exhale; we speak on the exhale
laryngeal system function in speech
larynx & vocal folds
supralaryngeal system function in speech
(vocal tract) the filter for speech; as we move it, the sounds change
what do the vocal folds do?
create our sound source
vocal folds are spread apart:
no phonation (abducted)
vocal folds are pulled together:
phonation (adducted)
what are the regions of the tongue from front to back?
tip, blade, body (front & center), dorsum (back), and root
articulation
moving the moveable parts
articulation in reguards to speech
the moveable parts of the vocal system that contribute to the production of consonants and vowels
what are the cavities in the supralaryngeal system?
nasal cavity (sinuses), oral cavity, and pharyngeal cavity (throat)
what are the 5 parameters of describing consonant production?
phonation, place of articulation, nasality, secondary articulations, manner of articulation
phontion
when the vocal folds are vibrating
places of articulation (7)
bilabial, labiodental, interdental, alveolar, alveopalatal, palatal, velar
bilabial
lips are closed together (b in boy)
labiodental
lips are between the teeth (f in fish)
interdental
tongue in between teeth (th as in think)
alveolar
blade of tongue hits roof of mouth (t as in toy)
alveopalatal
front of tongue hits roof of mouth (sh as in shoe)
palatal
front of tongue goes up towards roof (y in yellow)
velar
center of tongue hits roof (g in go)
nasality
when the velum is down (and the port is open) (n in nancy; allows air out of the noise)
secondary articulations
lateral: if the sides of the tongue are curled down (l in lady; you can feel air on sides of tongue)
central: if the sides of tongue are not curled down
retroflex: if the tip of tongue is curled up and back (r in rabbit)
manners of articulation
stops, fricatives (v,f), affricates (ch, j), approximants (consanats with vowel sounds)
3 parameters for vowel articulation
jaw height, tongue frontness-backness, lip shape
jaw height
high vowel (closed): jaw is raised (ea in seat)
low vowel (open): jaw is dropped (o in hot)
tongue frontness/backness
front vowel: tongue is advanced (foward; e in bet)
back vowel: tongue is retracted (au as in haul)
lip shaped
rounded vowel: lips are pursed (u in suit)
spread lip (neutral): lips are spread (ee in steep)
