Chapter 6 Flashcards
What allows for the percise movement of articulation?
The process of joining 2 elements
What does the vocal tract consist of?
Oral cavity, pharynx, nasal cavity
Source-Filter Theory
Speech is the product of sending an acoustic source (the source produced by vibrating out VF) through the filter of the vocal tract that shapes output
True or False: All articulators are mobile
False
What is the largest mobile articulator?
Tongue
What all all the mobile articulators?
Lips, tongue, velum
Immobile Parts
Bones of skull (maxilla- alveolar ridge, hard palate), Dentition (teeth), nasal bones, zygomatic bone (cheek)
Mobile Parts
Muscles (tongue, soft palate, muscles of face- lips cheeks), mandible (jaw), larynx/VF/Hyoid, pharynx and fauces (tonsil pillars)
Sounding Cavities
Mouth (oral cavity), Throat (pharyngeal cavity), Nose (nasal cavity)
Bones of the Face/Cranial Skeleton
Frontal bone, Parietal bone, Occipital bone, Temporal bone, Zygomatic bone, Mandible, Maxilla, Nasal bone, Sphenoid bone
Maxilla
Roof of the mouth, hard and solid separation of the oral cavity from the nasal cavity
Anatomical issues with the maxilla that impact speech production…
Cleft lip, cleft palate, cleft ulva, cleft lip and palate
What is the shape of the hard palate supposed to be?
Slightly rounded and smooth
High and narrow palatal arch
Is created when a kid sucks or uses pacifier for an extended amount of time- impacted teeth/crowded teeth/cross bite, tongue tissue involved, hypernasal speech, distorted palatal sounds
Super wide hard palate
Distorted palatal sounds, obstructed sleep apnea, snoring
Labial sounds
p,b,f,v,m
Dental sounds
t,d,th,n
Palatal sounds
r,j
Velar sounds
k,g,ng
Mandible
Floor of the mouth, this is where the tongue lives
Anatomical issues with the mandible that impact speech production..
Congenital mandibular hypoplasia (born with decreases formation of the jaw), micrognathia (small jaw), malocculoin of the jaw
Zygomatic bone
Cheek bones, forms the lateral portion of the nasal cavity
Why are teeth important?
Checking and Articulating
What the the teeth shapes/jobs
Sharp/thin - ripping, wide/flat- grinding
With teeth change over time what would be the impact of teeth on speech sound production…
missing teeth, misaligned teeth, mix of baby and adult teeth
Malocclusions (bite problems)
Overbite, underbite, tongue thrust
Resonance
A place for a vibration to live and be shaped within the cavities of the articulatory system
Where does the sound of the human voice resonate?
In the air spaces of the head and neck which are dictated by anatomical architecture
Source of vibration
Voice box- larynx produces voice by vibration of the BF powered by exhalation
Filter for vibration
Shaping through the vocal tract made by the tonge, mandible, soft palate, articulators
