1. Formation of Sound
Richard Fetter
3/6/14

2. 3 processes
-phonation
-resonation
-articulation

3. Phonation Sound -formed by vibrations in larynx
Volume and pitch controlled by
-respiratory muscles
-vocal tract

4. Adductory Sound
-folds held together produces vibration
-forms consonants
-full adduct is glottal stop

5. Abductory Sound
-caused by expansion of folds
-Partial opening is voiceless consonant

6. Sound pitch determined by
-Position in vocal tract
-Pressure changes
-Narrow= higher pitch

7. Aperiodic Phonation -Sound caused by airstream modification -produces
Plosive
Fricative
Africative
Voiced

8. Resonation and Articulation
-vocal tract is closed tube
-vowels are harmonics 1, 3, 5
-determined by tongue position
