1.
The soft palate serves to open and close the entrance to the nasal cavity.
Correct Answer
A. True
Explanation
The soft palate, also known as the velum, is a muscular structure located at the back of the roof of the mouth. It plays a crucial role in speech and swallowing. One of its functions is to open and close the entrance to the nasal cavity. When the soft palate is raised, it closes off the nasal passage, allowing air to flow through the mouth and preventing it from escaping through the nose. When the soft palate is lowered, it opens the nasal passage, allowing air to pass through the nose. Therefore, the statement is true.
2.
The space between the vocal folds is the epiglottis.
Correct Answer
B. False
Explanation
The epiglottis is a flap of cartilage located at the base of the tongue, not between the vocal folds. The space between the vocal folds is known as the glottis. Therefore, the statement that the space between the vocal folds is the epiglottis is incorrect.
3.
The vocal cords are pressed together during voiceless consonants.
Correct Answer
B. False
Explanation
During voiceless consonants, the vocal cords are actually held apart, allowing air to pass through freely. This is in contrast to voiced consonants, where the vocal cords vibrate to produce sound. Therefore, the correct answer is false.
4.
When the air is made to move out of the lungs, we say that there is an egressive pulmonic airstream.
Correct Answer
A. True
Explanation
When the air is expelled from the lungs, it is referred to as an egressive pulmonic airstream. This means that the airflow is moving outward, away from the lungs. This is a correct statement as it accurately describes the process of air being pushed out of the lungs during exhalation.
5.
Articulatory phonetics studies different parts of the vocal tract.
Correct Answer
A. True
Explanation
Articulatory phonetics is a branch of phonetics that focuses on the physical movements and positions of the various parts of the vocal tract involved in speech production. It examines how sounds are produced and articulated by studying the movements of the lips, tongue, jaw, vocal cords, and other speech organs. Therefore, the statement that articulatory phonetics studies different parts of the vocal tract is true.
6.
Which of the following is an active articulator?
Correct Answer
A. lower lip
Explanation
The lower lip is considered an active articulator because it is involved in the production of various speech sounds. It can move up and down, as well as protrude forward, to create different articulatory positions necessary for speech production. In contrast, the alveolar ridge, hard palate, and upper teeth are passive articulators, meaning they do not actively move during speech production but rather serve as points of contact or landmarks for the active articulators.
7.
Which part of the tongue forms the front wall of the pharynx?
Correct Answer
D. Back
Explanation
The root of the tongue forms the front wall of the pharynx.
8.
In the articulation of nasal sounds, the __________is lowered, and the air passes through the nose.
Correct Answer
D. Soft palate
Explanation
During the articulation of nasal sounds, the soft palate is lowered, allowing the air to pass through the nose. The soft palate, also known as the velum, is a flexible muscular structure located at the back of the roof of the mouth. When the soft palate is lowered, it creates a pathway for the air to flow through the nasal cavity, resulting in the production of nasal sounds.
9.
This articulator is called the voice box.
Correct Answer
C. Larynx
Explanation
The larynx is the correct answer because it is commonly known as the voice box. It is a part of the respiratory system located in the throat, and it plays a crucial role in producing sound and allowing us to speak. The larynx contains the vocal cords, which vibrate when air passes through them, producing sound waves that form our voice.
