  1. The vocal tract is composed of 3 cavities
    • Oral- mouth
    • Pharygeal- throat
    • Nasal- above the oral cavity
  2. Malocclusions
    • Class I- upper teeth overlap slightly
    • Class II- overbite
    • Class III-underbite
  3. Bones of the Cranium
  4. Orbicularis Oris
    • Orbicularis Oris- rounds the lips
    • Risorius- retracts the lips at the corner
    • Buccinator - lip retraction and cheek depresssion
  5. Levator Labii superiorioris muscle
    Zygomatic minor
    Levator labii superioris alaeque nasi
    All 3 upper lips elevators
  6. Zygomatic Major
    Depressor labii inferious
    depressor anguli oris
    • elevates and retracts angle of the mouth
    • pulls lips down and out
    • pulls lips down and out
    • wrinkles chin and depresses lower lips
  7. Palatoglossus
    • -elevates posterior tongue
    • -considered muscle of the velum
  8. Superior Longitudinal
    Function-lingual elevation and lateralization
  9. Inferior Longitundinal Muscle
    - pulls tip downward and/or lateralizes
  10. Transverse
    -narrows tongue
  11. Vertical
    -flattens the tongue and pulls tongue down
  12. Levator Veli Palatini
    elevates the velum and seals off nasal cavities
  13. Tensor Veli Palatini
    -tenses the velum and flattens it
  14. Vocal Tract Valves
    - labial, lingual, velopharygeal, laryngeal
  15. Source Filter Theory
    -states that energy from the source is modified by the resonance characterisitc of the filter
  16. Periodic Sounds
    • -generated by vocal folds
    • -vowels, diphthongs, semivowels- and nasals
  17. Aperiodic Sounds
    • -generated along the vocal tract
    • -voiceless stops, fricatives, and affricates
  18. Consonants
    -classified by place, manner, and voicing
  19. Place
    • Bilabial- /p/, /b/, /m/, /w/
    • Labiodental- /f/, /v/
    • Lingualdental- /-
    • Linguaalveolar- /t/, /d/, /s/, /z/, /n/, /l/
    • Linguapalatal- /
    • Linguavelar- /k/,/g/, /w/
    • Glottal-
  20. Manner
    • Obstruents (noise-turbulence)
    • -stops
    • -fricatives
    • -affricates

    • Sonorants (resonance)
  21. Vowels
    -classified by tongue height and position in oral cavity
  22. /e/ (mid- front)
    • /u /(high-back)
    • /a/ (low-central)
  23. Superior longitudinal
    Inferior longitudinal
    • Superior longitudinal- elevates tongue tip
    • Inferior longitudinal- depresses tongue tip
    • transverse- narrows tongue
    • vertical- groove tongue
    • genioglossus- protrude and retracts tongue
    • hypoglossus- depress tongue
    • styloglossus- retract tongue
    • palatoglossus - elevate posterior tongue
  24. Resonance results in ______ or ___ of the frequencies of the vocal fold vibration
    amplification or dampening
  25. Resonance is influenced by ___, ____ ,____ & ____ of the vocal tract
    length, shape, size, and openness
  26. Quarter-wave resonanator
    A tube open at one end and closed at the other
  27. Natural Resonant Frequence
    the frequency of sound to which the cavity most effectively responds

    Based on length of the vocal tract
  28. Formant
    • displayed as broad bands of energy in spectrogram

    • Ddd number multiples of Natural resonance frequency
    • F1- 500 Hz
    • F2- 1500 Hz (500 x 3)
  29. To Calculate the Formant Frequency
    • Vocal Tract x 4 = Wavelength
    • Wavelength/ Speed of Sound = F1

    Speed of sound 34,000 cm/sec
  30. Formants are dependent on the
    volume and length of oral cavity

    • F1 - pharyngeal cavity
    • F2- oral cavity
