What is the source-filter theory

-larynx serves as source and the vocal tract is filter
**independent of each other

What are the different source changes

-loudness
-pitch
-voice quality
-phonation vs. whispering

How do you change the loudness of the source

-provide more pressure from the lungs to the larynx

How do you change the pitch of the source

-stretching the vocal folds which changes the intensity of how the vibrate

how do you change the voice quality of the sound source

- adjusting the space between the vocal folds
*specifically between the arytenoids

Whispering

-no vibration but still a sound source from using air from lungs

what is a harmonic spectral slope

1|Page

,Higher harmonics progressively slope because they are weaker in amplitude then the fundamental

What does the vocal tract filter do?

-weakens what comes out of larynx
- resonates 'echos' sound
-some sine waves add
-constructive interference

What is the vocal tract transfer function

-change in sound between entering the vocal tract and leaving the vocal tract
(new sound- old sound)

What influences is?

resonating cavities in the vocal tract between the larynx and the lips
***VARIABLE FILTER

What is a formant

a resident peak in the vocal tract transfer function

How do formants change during speech?

some frequencies in a given range are amplified in their amplitude and are more prominent than any
other sounds in the spectrum
*reflects the way the vocal tract is shaping the sound that the larynx gave to it*

How do formants differ for men women and children

-Men's vocal tracts are largest which alternates the frequencies
-Children have highest formant frequencies (smallest structures)

place, manner and voicing of stops

place: bilabial
manner: brief closure of the vocal tract
voicing: voiced or voiceless

transition of stops

vocal tract adjusts for next sound.

transient and friction of stops

-air pressure builds behind closure
-transient- first burst of air
-frication-air flows through narrow gap
**often hard to seperate

VOT for /b/ /d/ /g/


2|Page

, -20 to +20ms

VOT for voiceless stops

20-100ms

duration of a CV transition

about 50ms

what does F1 relate to

mouth opening

C to V transition

F1 will increase

place of articulation determines

spectral shape

fricatives

longer than stops

affricates

shorter than fricative, longer then stop

What is another name for volume velocity

Air flow

How do you calculate the average air flow (volume velocity)

volume/time

What is a u-tube manometer

A tube in the shape of a 'U' that is used to measure pressure and can be used to calibrate electronic
equipment to measure pressure.

How does a u-tube manometer work?

Pressure will displace the water and the displacement can then be measured by measuring the
difference in height

What is a u-tube manometer best used for?

Calibrations of equipment and measuring static pressure

What are the limitations of a manometer

Measuring speech production where the pressure goes up and down rapidly.
