Speech Science Foundations

Question 1

acoustatically

Answer 1

fundamental frequency (Hz)
intensity (dB)
time

Question 2

Physiologically

Answer 2

endoscopy, fluorography, oral facial sensory motor

Question 3

Perceptually

Answer 3

articulation testing, listening to speech sounds, spontaneous or prompted

Question 4

Acoustics

Answer 4

branch of physics that studies properties of speech

Question 5

Inertia

Answer 5

resistance when force is exerted upon an object

Question 6

elasticity

Answer 6

tendency of an object to return to its original state

Question 7

cycle

Answer 7

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

Question 8

Amplitude (A)

Answer 8

maximum displacement of particles in a medium; perceptually related to intensity/loudness; not 1:1 relationship

Question 9

Frequency (F)

Answer 9

rate at which object vibrates; number of cycles in 1 sec (Hz); perceptually rates to pitch; not 1:1 relationship

Question 10

Period (T)

Answer 10

amount of time required for 1 complete cycle; need period of wave to figure out the frequency

Question 11

Pure tones

Answer 11

has only 1 frequency; sinusoidal motion or simple harmonic motion

Question 12

Sine waves

Answer 12

periodic; cycles will repeat themselves identically

Question 13

complex periodic waves

Answer 13

complex: more than 1 freq present
periodic: the complex pattern repeats over time

Question 14

complex aperiodic waves

Answer 14

complex: more than 1 freq present
aperiodic: no cyclical or pattern behavior

Question 15

Fundamental frequency F0

Answer 15

lowest pure tone component of sound

Question 16

parials/overtones

Answer 16

all other frequencies present in a sound (excluding fundamentals)

Question 17

Harmonics

Answer 17

whole # multiples of fundamental frequency (F0 X Nth Harmonic)
1st harmonic- F0 -> 2nd harmonic- 2(F0) -> 3rd harmonic- 3(F0)
