Formation of Sound Richard Fetter 3/6/14

3 processes -phonation -resonation -articulation

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

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

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

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

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

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