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 |
