1. When we use the terms "airstream mechanism" or "airstream processes," we are referring to two aspects of the airstream. To which aspects are we referring?

1. Choose the correct description about Boyle's law.

1. The lung is the initiator for pulmonic airstream mechanisms. What are the initiators of the following air stream mechanisms?

1. Stop sounds made with a glottalic egressive airstream mechanism are called ejectives. What are the names of the stop sounds made with the following airstream mechanisms:

5: The following is a step-by-step description of how the alveolar ejective sound is produced (again, ejectives are stop sounds made with a glottalic egressive airstream mechanism).

Steps to produce an alveolar ejective:

1. Close the glottis and make a complete closure at the alveolar ridge.
2. Raise the glottis.
3. Oral pressure then increases.
4. Release the constriction at the alveolar ridge.
5. Air is forced out, creating an ejective sound.

1. Please complete the same description for the sound .... Some steps are already given.

Steps for ...:

1. Which of the following description is matched with its IPA symbol?

1. Which of the following lists only consists of implosives?

1. The basic aerodynamic requirement for voicing is Po < Ps. This means (circle one):

1. Another term for 'creaky voice' is (circle one):

1. Which of the following lists only consists of breathy stops?

1. Which of the following definition describes a positive VOT?

1. Choose the voicing and VOT characteristics for the following stop according to the acoustic wave form of the stop.

1. Choose the voicing and VOT characteristics for the following stop according to the acoustic wave form of the stop.

1. The vibrating frequency of a string depends on two properties: length and tension. Explain how the fundamental frequency changes depending on these two properties.

1. Regarding length:

1. Regarding tension:
