What can resonance in the vocal tract do?
increase the amplitude of some frequencies even as it weakens the amplitude of others
T or F: The sound that leaves the vocal tract has been substantially changed from what it was when it entered.
What do tubes do if they don't generate sounds?
They shape and alter sounds that are put into them
What of a tube allows for resonance?
The best resonance frequency of a tube (the one that causes it to resonate or echo the best) depends on...
The best resonance you will get will be for sounds that have a wavelength ....
4 times that of the tube
A small tube will resonate ____ frequencies because they have ____ wavelengths.
A long tube will resonate ____ frequencies because they have ____ wavelengths.
Is the vocal tract a uniform tube?
no, the diameter will vary along it's length
T or F: The vocal tract will change the blend of frequencies and the strength of different harmonic components as they make their way through the tube that has different sections of different diameters
T or F: A tube of a certain length will favor a given frequency due to it dimensions
A shorter tube will favor or resonate sounds that have a ____ wavelength.
If the wavelength is shorter, the frequency is ____?
A longer tube will favor or resonate sounds that have a ____ wavelength?
If the wavelength is longer, the frequency is ____?
You change the size and shape of the vocal tract along the way by moving your ....
T or F: the sound going into the vocal tract is not the same as the sound that comes out of the vocal tract
The way the sound changes from the larynx to the lips is referred to as the ...
vocal tract transfer function
Input comes from the larynx and is and is similar to a ....
The resonating cavities between the ____ and the ____ will determine the transfer function/exact nature of the sound
The transfer function is a ____ filter. It is changing all the time as we move our articulators.
What is a formant?
a resonant peak in the vocal tract transfer function
What is a resonant peak in the vocal tract transfer function?
T or F: Some frequencies in a given range are amplified to boost their prominence in the spectrum (formants)
Are they a set number of formants for a given vowel?
Which formants are of the most interest?
first 2 or 3
Does a formant create sound?
What does a formant reflect?
the way the vocal tract is shaping the sound coming out of the larynx
Will a formant be created for whispering, phonation, or both?
How is fundamental frequency is changed?
by raising and lowering your pitch while maintaining the position of the articulators
How can you change the filter characteristics and not change fundamental frequency?
hold the same pitch and move articulators to create different sounds
