Q

comparing SD in Hz would be easy if the mean were the same for all users, if the mean is not the same… what do we do?

A

convert to semitones and then compare

Q

most laryngeal disorders do not substanially affect F0 what is an exception

A

vocal fold edema, fluid build up, more mass on vocal folds = lower pitch

Q

hoarseness of a voice may lead to the perception of a pitch change. why?

Q

alaryngeal speech what is it.

A

when some cancer patients, or patients lose their larnyx, the esophogeal sphincter (valve at the top of the esophagus that is usually closed) vibrates for the larnyx. Pretty much speaking in the same place that we burp

16
Q

F0 can be high or low when using alaryngeal speech

A

low, due to how large the structures are around the esophageal sphincter. they are larger taking more energy to oscilate..

Q

the voice can do, max performance, ask the person to phonate /a/ in modal register, (avoiding fry) and in the falsetto. or loft register

Q

the ability to alter our pitch to representative of what?

A

vocal health and neuro motor abilities

20
Q

how to practice effects affect our F0 range?

A

repeated attempted can widen or increase our range,

21
Q

how does a glissando help during a vocal range assessment

A

a glissando upward and downward may help see full range and lessen the risk of vocal damage.

22
Q

IN REGARDS TO THE SOURCE-FILTER MODEL, the larnyx serves as the

A

source

23
Q

IN REGARDS TO THE SOURCE-FILTER MODEL the filter is the

A

vocal tract

24
Q

the filter selects certain vibrations why?

A

certain frequencies viberate the best at certain points, and resonates them

25
Q

the source and filter are independent but interact with each other, true or false

A

true

26
Q

how can we vary the source of vocality’s

A

Loudness, Pitch, Voice quality, and phonation versus whispiering,

27
Q

How does air pressure change on our vocal folds when we are shouting versus talking

A

When we are shouting there is a higher air pressure, and it forces the vocal folds to vibrate larger. When we stretch the vocal folds they increase the frequency of how they will vibrate

28
Q

What is the fundamental frequency in regards to vocal fold oscillation

A

the rate at which they oscillate

28
Q

when the F0 goes up the harmonics ______

A

go up and spread,

28
Q

Harmonics are integer_____ of _________

A

Multiples; fundamental

29
Q

what is a harmonic series

A

fundamental plus the harmonic components

29
Q

harmonics plus fundamental

A

harmonics spread

30
Q

men average at what Hz? what about for women?

A

100-120hz and 200Hz- 240Hz

30
Q

Harmonic spectral slope

A

as the F0 gets higher, the harmonics became less and less present, forming a negative relationship between the two. this presents how frequency decreases over time

30
Q

the higher the F0 = greater spread between _________

A

harmonics

31
Q

As the F0 rises and falls, so does the

A

the space between harmonics

32
Q

The vocal tract filter, does not just bring attention or remove sounds, but

A

also resonates them

33
Q

what is constructive interference

A

waves that are in phase with one another, adding up to create a larger wave, or sum of waves

34
Q

what is deconstructive interference

A

when waves that are 180 Degrees out of phase with one another, silencing or cancelling each other out

35
Q

What does attenuation mean in regards to the vocal tract filter

A

it means that it brings attention to specific freqnecies of the wave, or resonate, changing the sound

36
Q

tubes do not create sounds but rather they

A

resonate them, or their dimensions allow for stronger resonance at specific frequencies

37
Q

resonance fo a tube depends on

A

the tubes length, shape and dimensions

38
Q

max resonance for waves with a length _____

A

4 times that of the tube

39
Q

Short tubes best resonate what sound? what about Long tubes?

A

short = higher freq
long = lower freq

40
Q

how does a tube affect a sound? what aspects or physical properties affect sound

A

the constriction locations on the tube, and how severe the constrictions are. changes what frequencies it allows depending on the size

41
Q

contrictions formed from articulation are what

A

constrictions being bringing the tounge to the opposing structure, and changing the size of the vocal tract, and changing the size of the oral cavity or pharnyx

42
Q

the vocal tract can be thought of as a tube changing shapes, true or false?

A

true, it allows certain frequencies to be boosted, or damped.

43
Q

The output our vocal tract creates is different from the input it recieved from the from the larynx,

A

in put can look like a saw tooth wave, is changed by our filters and pharnyx.

44
Q

when moving from the filter (mouth tounge, teeth) to the pharnyx, then to the larnyx, it becomes in what pattern wide and narrow?

A

wide in the mouth area, narrow in the pharnyx area, and larger in the larnyx area
