2. Oral Cavity • Anatomy • Lips • Oral cavity • Teeth • Hard palate • Soft palate • Uvula • Tonsils • Tongue

3. Question Which is not a part of the oral cavity? • Uvula • Soft palate • Pharynx • Lips • Hard palate

4. Lips • Anatomy • FAS

5. Question Cupid bow is: • Upper lip • Lower lip • Chin • Nose • A novel

6. Facial Muscles • Anatomy • Facial muscles

7. Question Which muscle helps round the lips? • Obicularisoculi • Obicularisoris • Obicularis oracle • Obicularis occipital

8. Teeth • Anatomy

9. Dental Occlusion • Types

10. Hard Palate • Anatomy • Oral cavity • Hard palate

11. Soft Palate • Anatomy

12. Tongue • Anatomy

13. Function of Soft Palate • Velopharyngeal port • nasality

14. Passavant’s Pad • A prominence on the posterior wall of the naso-pharynx formed by contraction of the superior constrictor of the pharynx during swallowing. • Synonym: Passavant'sbar, Passavant'spad, Passavant'sridge.

15. Speech Production • Phonemes (sound units of language) • Consonants (s, z) • Voiced (z) • Unvoiced (s) • Vowels (i) • Diphthongs (oy)

16. Production of Consonants • Place of production • Where major constriction occurs in vocal tract • Manner of production • How consonant is produced • Voicing (phonation) • Voiced or unvoiced

17. Place of Production • Bilabial • Labiodental • Dental • Alveolar • Palatal • Velar • Glottal

18. Manner of Production • Stops • Fricatives • Africates • Nasals • Semivowels

19. Alphabet Soup • 26 letters of alphabet • Only list consonants • Digraph consonants • Other consonants

21. Male Vocal Tract 17.2 cm 17.2 cm Tube open at one end, closed at the other ¼ Wave Resonator

22. Vocal Tract Resonators (Filter) • Tube open at both ends • ½ resonator • Tube closed at one end and open at the other • ¼ resonator

23. Vocal Tract (Filter) • Approximately 17.2 cm for males • 5/6 the length for females • Children roughly half the length of adult male Assignment

24. Source-Filter Theory Fo (source produced at vocal folds) Formants (F1, F2, F3, …) created by vocal tract resonance Source which is emphasized and not modulated by vocal tract resonance (F1, F2, F3, shown at left)
