|---|---|---|---|---|---|
| 3 Speech Production Components | 1)Power Supply (the lungs)
2)Sound Source (vocal folds
3)System of Valves (articulators)
🗑
|
||||
| Speech Production Processes | *Respiration
*Phonation
*Articulation/Resonance
🗑
|
||||
| Mesurement of sound pressure | micro pascales uPa/cm2
🗑
|
||||
| Mesurement of air pressure | cm H2O
🗑
|
||||
| What is used to measure Barometric Pressure? | Barometer
🗑
|
||||
| What is used to measure air Pressure? | Manometer
🗑
|
||||
| What sections of body participate in respiratory function? | Thorax & abdomen
🗑
|
||||
| Pulmonary System | *Upper Airways = nose, mouth, throat, & larynx
*Lower Airways = trachea
🗑
|
||||
| 2 types of respration | 1) Quiet/Reflexive Respiration
*Quiet Inspiration and Quiet Expiration
2) Active Respiration
🗑
|
||||
| Function of the diaphragm in quiet inspiration | *responsible for 75% of the muscular effort
*pulls lungs down, increasing their vertical dimension
🗑
|
||||
| Function of the external intercostals in quiet inspiration | -responsible for 25% of the muscular effort
-muscles found in spaces between ribs; raises each rib below
🗑
|
||||
| Negative Alveolar Pressure | -By increasing the size of the lungs, a partial vacuum is formed. This creates Negative Alveolar Pressure
-Air rushes into the lungs to equalize the air pressure
🗑
|
||||
| Quiet Expiration | *non-muscular
*When inspiratory muscles relax, the stretched lungs return to their normal resting size due to elasticity.
*Thus, air expires due to the elastic recoil of the lungs
🗑
|
||||
| Active Respiration | *When you exercise conscious control of your respiratory system.
*greater amount of air is inhaled
*faster intake of air
*more muscle groups involved
*e.g.sucking through a straw , blowing up a balloon ,blowing out a candle,playing a wind instrument
🗑
|
||||
| Muscles of Active Inspiration | -diaphragm, external intercostals, and 9 different sets of muscles can be involved.
Ex: Pectoralis0, Sternocleidomastoid , Latissimus Dorsi , Subclavius
🗑
|
||||
| Active Expiration | Used whenever expiratory demands are greater than can be achieved by the elastic recoil of the lungs alone
🗑
|
||||
| Muscles of Active Expiration | *involves 9 sets of muscles, including Internal Intercostals and a variety of Abdominal muscles
🗑
|
||||
| Relaxation Pressure | The pressure produced entirely by the elastic recoil of the lungs (non-muscular)
🗑
|
||||
| When are expiratory muscles used in respiration? | Any time the task requires more air than can be provided by relaxation pressure
🗑
|
||||
| When are inspiratory muscles used in expiration? | Any time the tasks demands LESS air than is provided by relaxation pressure. Slows down the rate of air coming out. Used for conversation speech, singing etc...
🗑
|
||||
| The only time expiratory muscles are used during speech is when... | the air flow demands are greater than can be produced by relaxation pressure.
🗑
|
||||
| 2 situations when expiratory muscles are used in speech | 1)Near the second half of an utterance, if the speaker chooses to finish a long sentence without pausing to take a breath
2)If the speaker shouts or talks louder than usual
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
