Nonspeech Laryngeal Functions Coughing Throat Clearing Abdominal Fixation Laryngeal Dilation (abduction) Swallowing
Laryngeal Functions for Speech Phonation
Vocal Attack The process of bringing the vocal folds together to begin phonation, requiring muscular action
Types of Vocal Attack: Simultaneous, Breathy, Glottal
Bad Vocal Attacks Hard Glottal and Breathy Phonation (extreme)
Sustained Phonation Maintenance of laryngeal posture thru tonic contraction of musculature
Modes of Vocal Fold Vibration Vertical Mode: open from inferior to superior and also close from inferior to superior Anterior-Posterior Mode: open from posterior to anterior, but closure at the end of the cycle is made by the medial edge of the v.f., with posterior edge closing last
Modal Register Modal Register is used for conversation. 2 variations: Pressed – medial compression of the vf’s is greatly increased. Breathy – medial compression of the vf’s is greatly decreased; variations = air wastage, inefficient.
Vocal Register: Glottal Fry (Pulse Register) Extremely low pitch, rough in nature decreased respiratory support (takes about 2cm H²O). Tension of the thyrovocalis is reduced. Vocal folds are adducted about 90% of the time.
Vocal Register: Falsetto Highest register; vocal folds lengthen and become thin, tend to vibrate along the bowed margins. They make contact only briefly and the degree of movement is reduced
Vocal Register: Whistle a register above falsetto; not a mode of vibration as much as it is a result of turbulence across the vocal folds – occurs as high as 2500 Hz.
Vocal Register: Whispering : not a true phonatory mode, but it does require laryngeal adjustments.
Pitch Perception of frequency
Average Fundamental Frequency Reflects habitual pitch over a longer averaging period (sustained vowel productions, reading passages, conversational sample).
Pitch Range The lowest to highest pitch a person can produce (usually 2 octaves).
Pitch Changing Produced by changing tension, length, and mass of the vocal folds: Increase tension, increase pitch Increase length, increase pitch Decrease mass, increase pitch
Intensity Changes Loudness is the correlate of intensity. Increase vocal intensity by increasing subglottal pressure and medial compression. Can increase pitch without increasing intensity – separate mechanisms
Terminate Phonation Abduct the vocal folds
Caroline is ___. Cool
