25
What are all the parts of the Larynx?
- epiglottis - Hyoid Bone - Thyroid Cartilage - Circoid Cartilage - Laryngeal Prominence - Tracheal Cartilages
26
Describe the Epiglottis
Sits at top of Larynx No function in speech Flap of tissue Seals of larynx in swallowing
27
What are the three systems involved in speaking called?
Respiratory Phonatory Articulatory
28
What is inspiration when speaking?
Breathing IN
29
What is expiration when speaking?
Breathing OUT
30
Where does the air travel when we breathe in?
Down the trachea, bronchi and into the lungs
31
What is it called when we use air coming from the lungs?
The pulmonic egressive airstream mechanism
32
What does pulmonic mean?
Lungs
33
What does egressive mean?
Outward flow
34
What is the ratio of inspiration to expiration during quiet breathing?
1:1
35
What is the ratio of inspiration to expiration during speech?
1:8
36
Where is the larynx situated?
At the top of the trachea
37
What are the two cartilage in the larynx and what is their purpose?
The thyroid and the Cricoid | They protect the vocal folds
38
What is the space between the two vocal folds called?
The glottis
39
What is subglottal?
Part of the vocal tract below the glottis
40
What is supraglottal?
Part of the vocal tracts above the glottis
41
When fully open, how much of the trachea is the glottis?
54%
42
What happens when air travels up the trachea from the lungs?
It must pass from a wider to a narrower area when it reaches the glottis
43
What must happen to produce voicing?
The vocal folds vibrate
44
What is the process of voicing ( vocal fold vibration)?
The first meet along the bottom edge and the line of closure then travels upwards. When it reaches the top, the bottom edges are already opening again. This creates a vertical phase difference. Breath escapes during each opening (thus escapes in pulses).
45
What is pitch?
The frequency of vocal fold vibration
46
What is different in male and females and what is due to?
Pitch, due not the size of the vocal folds.
47
What are the measurements of the inner edge of the vocal folds in men and women
Male- 23mm | Female- 18mm
48
What is the average pitch for males and females?
Males - 100-150Hz | Females- 200-300Hz
49
What does volume depend on?
The amplitude of vibration of the vocal folds.
50
Describe how we change our volume?
The further the vocal folds move apart in the open phase, the louder the sound; the smaller the gap, the quieter the sound. To produce a loud voice, extra pressure is also needed from the lungs.
51
What is the articulatory system often referred as?
Supra-glottal system
52
Where is the pharynx?
The chamber above the larynx
53
What is the pharynx?
Mainly a container of a volume of air which can be set in vibration sympathy with the vibrations of the vocal folds ( this amplifying sound)
54
Where is the epiglottis?
Sits at the top of the larynx
55
What is the epiglottis?
It is a flap of tissue which projects into the pharynx at the root of the tongue.
56
Where does the soft palate (velum) terminate?
In the fleshy uvula
57
What happens if the velum is raised or lowered?
It closes or opens the entrance to the nasal cavity (velopharyngeal port)
58
What is the velopharynx?
The nasal cavity
59
What does the roof of the mouth consist of?
Alveolar ridge, hard palate and soft palate
60
What determines the size of the oral cavity?
The mandible
61
What are the four shapes that the lips can make?
* Close rounding * Open rounding * Spreading * Neutral
62
What is the most flexible organ of speech production?
The tongue
63
What is the tongue?
A combination of muscles whose base is attached to the hyoid bone
64
What are the four sections of the tongue?
* The blade – tapering section behind alveolar ridge * The tip – extreme point of the blade * Front – part lying under the hard palate * Back – part lying under the velum
