AnaPhy of Resonation Flashcards
Resonation is determine by the following:
Length & volume of the pharynx
Size and shape of the oral cavity
Configuration of the nasal cavity
Muscular tube that connects the nasal cavity and larynx
Pharynx
3 parts of the pharynx
Nasopharynx, Oropharynx, Hypopharynx/ Laryngopharynx
Length and volume of the pharynx are modified by 2 things. What are these?
Tongue Position
Vertical Positioning of the Larynx
Resonance is determined by what?
Size and shape of the vocal tract
Shorter, smaller cavities: enhance [higher or lower?] formants/ frequency [increases or decreases?]
higher, increases
Longer, larger cavities: enhance [higher or lower?] formants/ frequency [increases or decreases?]
lower, decreases
Raises and contacts the posterior pharyngeal wall during speech
Velum/ Soft Palate
What structure closes the opening between the nasopharynx and oropharynx - also called as the velopharyngeal port
Velum/ Soft Palate
Velar muscles
Opens eustachian tube
Tensor Veli Palatini
Velar muscles
Brings velum up and back / closes the velopharyngeal port
Levator Veli Palatini
Velar muscles
Brings velum down; narrows pharynx
Palatopharyngeus
Bulge on nasal surface for tight velopharyngeal closure
Musculus uvulae
Innervation of velar muscles, except Tensor Veli Palatini
CN 10 (Vagus)
CN 11 (Spinal Accessory)
Innervation of Tensor Veli Palatini
CN 5 (Trigeminal)
Velopharyngeal Port Closure Patterns
Coronal (Velum + PPM)
Sagittal (LPW)
Circular (All structures)
Circular with Passavant’s ridge (All structures + Passavant’s ridge)
Most significant cavity of speech mechanism, undergoes most change during speech act
Oral Cavity
Point of exit for all orally emitted sounds (except nasals)
Oral Cavity
To produce oral sounds, the velum has to go ____ via the levator veli palatini muscle
back and up
Point of exit for all nasal sounds
Nasal Cavity
To produce nasal sounds, velum is _____
lowered and relaxed
Different vocal tract shapes lead to different frequency filters
Source Filter Theory
What is considered the source in the source-filter theory?
Vocal Folds
What is considered the filter in the source-filter theory?
Vocal tract
Integers of the fundamental frequency
Harmonic frequency
