Speech Science

Question 1

Acoustics

Answer 1

branch of physics that studies properties of sound

Question 2

Inertia

Answer 2

resistance when force is exerted upon an object

Question 3

Elasticity

Answer 3

Tendency for an object to return to original state

Question 4

Cycle

Answer 4

each individual vibration
- period (time of 1 full cycle)
- frequency (# of cycles in 1 second)

Question 5

Amplitude

Answer 5

loudness or the amount of maximum displacement of vibrating particles of the medium

Question 6

Frequency

Answer 6

rate at which object vibrates; number of cycles in 1 second
- perceptually related to pitch; not 1:1 relationship

Question 7

Period

Answer 7

amount of time required for 1 complete cycle

Question 8

Pure Tones

Answer 8

sound that consists of one single frequency

Question 9

Sine Waves

Answer 9

periodic, cycles repeat themselves identically

Question 10

Complex Periodic Waves

Answer 10

1. Complex: more than 1 frequency present
2. Periodic: complex pattern repeats over time

Question 11

Complex Aperiodic Waves

Answer 11

1. Complex: more than 1 frequency present
2. Aperiodic: no cyclical or pattern behavior

Question 12

Fundamental Frequency

Answer 12

lowest pure tone component of sound

Question 13

Harmonics

Answer 13

whole # multiples of fundamental frequency

Question 14

Acoustic Phonetics

Answer 14

how speech sounds are produced and how
they are transmitted as sound waves,
analyzing properties like pitch, volume,
and timbre.

Question 15

Auditory Phonetics

Answer 15

how we perceive and process speech
sounds through our auditory system and
brain.

Question 16

Articulatory Phonetics

Answer 16

how speech sounds are physically
produced by the articulators (e.g. lips,
tongue, teeth, etc.).

Question 17

Applied/Clinical Phonetics

Answer 17

The practical application of phonetic
research to assess and treat speech
disorders.

Question 18

Experimental Phonetics

Answer 18

the use of scientific experiments and
measurements to study the properties of
speech sounds.

Question 19

Descriptive Phonetics

Answer 19

The study and classification of the sounds
used in different languages and dialects.

Question 20

Diaphragm

Answer 20

Primary muscle for breathing; it tightens to
expand chest and pull air into lungs.

Question 21

External Intercostals

Answer 21

Raises ribs to widen chest and lower pressure,
helping breathe in air

Question 22

Internal Intercostals

Answer 22

Pushes ribs down to shrink chest and force air
out during exhale.
