week2 Flashcards
what are the 3 things in Levelt speech production model
conceptualisator
formulator
articulator
what is the conceptualisator
one one level you produce speech on conceptual level (message generation based on your knowledge)
what is the formulator
you put the conceptually produced speech into a grammatical encoding.
formulator makes use of:
lexicon
what does the lexicon do?
chooses words and takes the right version of the word (also called lemma) (the right version of the word). Retrieves the words to fit the concept.
what is a spectrogram
a graph of amplitudes of frequency for different timesteps
what are formants
formants are indicating frequency bands where the amplitude is the strongest. This allows you to find vowels since these have more constant frequencies.
what does wernikes area
processes sound & tells how language should be spoken
what does broca’s area
articulation of speech
3 places in the body where speech is made
supra-glottal system
glottal system
sub-glottal system
what does supra-glottal system?
filters the actual sound = articulation phase
glottal system does:
glottis regulates the airstream = phonation
sub-glottal system
where you initate energy with pressure = initiation
what 3 places exert the initiation phase?
pulmonic (lungs)
glottalic (larynx)
velaric (tongue)
phonation is basically
changing air stream mainly through resistance
where takes phonation place?
at larynx (vocal chords)
if sound is voiced then there is a lot of
vibration in vocal folds
phonation determines
the loudness
opening and closing and lengthening and shortening the vocal folds regulate:
pitch
opening and closure of the vocal folds is called
glottal pulses
where does articulation take place?
active articulators and muscular movements
what 2 spaces in the body act as helmholz resonators?
- oral cavity
- pharyngeal vacity
what makes articulation possible
helmholz resonators
