Question 1

The laryngeal system&#10;A)Shapes air stream into speech sounds&#10;B)Provides the essential air supply&#10;C)Generates the sound&#10;D)Acts as a resonator&#10;E)A and D

Accepted Answer

The laryngeal system, specifically the vocal folds within the larynx, generates sound by vibrating as air passes through them.

Question 2

The respiratory system&#10;A)Shapes air stream into speech sounds&#10;B)Provides the essential air supply&#10;C)Generates the sound&#10;D)Acts as a resonator&#10;E)A and D

Accepted Answer

The main function of the respiratory system is to provide the essential air supply to the body. While it is involved in speech production through the movement of air through the vocal cords, it does not shape the air stream into speech sounds, generate the sound, or act as a resonator in the same way that the vocal tract does.

Question 3

The acoustics and perception of sound constitutes the physics of speech.

Accepted Answer

Acoustics is the branch of physics concerned with the properties of sound and its production, transmission, and effects. The perception of sound involves the processing of sound waves by the auditory system, which is the focus of the study of psychoacoustics. Speech is a complex combination of sound waves that is produced by the movement of the vocal tract and is perceived by the auditory system. Therefore, the physics of speech involves both acoustics and psychoacoustics.

Question 4

Production of the /p/ phoneme probably involves movement of the&#10;A)Teeth&#10;B)Hard palate&#10;C)Lips&#10;D)None of the above

Accepted Answer

The /p/ phoneme is a bilabial stop, which means that it is produced by a complete closure or blockage of airflow by the lips. As air is built up behind the closure, the pressure increases until the lips are finally released, causing a burst of sound. The movement of the lips is therefore a crucial aspect of producing the /p/ sound. The teeth and hard palate may come into play in creating different variations of the /p/ sound, but they are not essential for producing the basic sound itself.

Question 5

With contralateral neural control,the right side of the brain controls the right side of the body.

Accepted Answer

With contralateral neural control, the right side of the brain controls the left side of the body, and the left side of the brain controls the right side of the body.

Question 6

In most people,the right hemisphere is dominant for language.

Accepted Answer

In most people, the left hemisphere is dominant for language.

Question 7

Since speech involves producing actions on a stream of air,it is viewed as an aerodynamic system.

Accepted Answer

Speech production involves the movement of air through the vocal tract, which makes it an aerodynamic system.

Question 8

Phonation occurs when&#10;A)Vocal folds vibrate in the presence of air flow&#10;B)Vocal folds release mucous&#10;C)The larynx opens and closes&#10;D)The vocal folds vibrate in a vacuum created in the larynx

Accepted Answer

Phonation is the process of generating sound by the vibration of vocal folds. This vibration occurs when the vocal folds are set into motion by air passing through them, causing them to rapidly open and close. Therefore, option A is the correct choice. Option B is incorrect as mucous is not related to phonation, option C is incorrect as it describes the opening and closing of the larynx and not the vibration of the vocal folds, and option D is incorrect as vocal fold vibration requires air flow.

Question 9

The expiration phase of respiration is longer for speech than for quiet breathing.

Accepted Answer

During speech, we need to control the release of air for a longer period of time to produce the appropriate sounds and intonation, compared to quiet breathing. Therefore, the expiration phase of respiration is longer for speech.

Question 10

The vibratory motions of the vocal folds may be described as a series of&#10;A)Forward and backward waves&#10;B)Openings and closings&#10;C)Shakes and shimmers&#10;D)Rises and falls

Accepted Answer

The vocal folds vibrate by repeatedly opening and closing, creating a series of cycles during phonation. This opening and closing can be described as the vocal folds "flapping" or "pulsing" to create sound waves. Therefore, option B is the most suitable choice.
