Comd 5070 chapter 6 review questions Behrman
With 100% Solved Answers
The voice source is basically - ANSWER-the pressure wave generated by the vibrating
vocal folds
When the air inside a partially or completely enclosed container is set into vibration, we
say that the container is a/an - ANSWER-acoustic resonator
The characteristic resonances are called - ANSWER-formants
The glottal volume velocity is the volume of air flowing through the glottis as a function
of - ANSWER-time
A triangular wave contains, in theory, an infinite number of harmonics, each of which is:
- ANSWER-an odd-numbered multiple of the F0
The decrease in harmonic amplitude with increasing frequency of the harmonic is
referred to as what characteristic of the spectrum? - ANSWER-the roll off
In general, the faster the cutoff of the airflow, corresponding to faster vocal fold closure,
the greater the excitation of the column of air in the - ANSWER-vocal tract
What is the input energy, raw material if you will, for the acoustic resonator, the vocal
energy - ANSWER-the source spectrum
The neutral vowel /e/, is called a/an - ANSWER-schwa
When producing the neutral vowel, the vocal tract is fairly uniform along its length. This
length is, on average, approximately how many cm in adult males, how many cm in
adult females, and how may cm in small children? - ANSWER-males=17.5
females=14.7
children=8.75
For specification of a given vowel, only which formant(s) is/are required - ANSWER-the
first three
The overall length of what will have a dramatic effect on the frequency location of the
formants? - ANSWER-the vocal tract
As the formant frequencies are increased, the spacing between the formants -
ANSWER-decreases
, Raising the larynx upward in the neck has what effect on the vocal tract - ANSWER-
shortens it
The radiation characteristics at the lips favor which components of the sound wave? -
ANSWER-high frequency
What kind of waves are the result of constructive interference of an incident and
reflected wave? - ANSWER-standing
Air particles vibrate most effectively at what part of the tube that is closed at one end
and open at the other? - ANSWER-the open end
Vocal tract formants represent what kind of resonances of the vocal tract? - ANSWER-
potential
Relative to voice source characteristics, what is an irregularity of frequency (jitter) or
amplitude (shimmer) called? - ANSWER-perturbation
All formants are lowered by - ANSWER-labial constriction
F3 is most influenced by the position of - ANSWER-the tip of the tongue
The most extreme high vowels are /i/ and /u/. The lowest vowels are /ae/ and /a/. The
most front vowels are /i/ and /ae/, and the most back vowels are /u/ and /a/. These four
vowels are referred to as the - ANSWER-corner vowels
As the vowel becomes lower or more open F1 - ANSWER-increases
The movement of the articulators will create different sized resonating spaces, the
larger of the resonating spaces will produce the: - ANSWER-lower formant frequencies
The ability of the individual to assume different articulatory postures to achieve the
same acoustic output is referred to as - ANSWER-motor equivalence
The cardinal vowels are supposed to represent the pronunciation in - ANSWER-an ideal
pronunciation of extremes of tongue position
Generally, by convention, when the primary and secondary cardinal vowels appear
together in pairs in the vowel quadrilateral, within the pair the vowel with lip rounding
appears - ANSWER-on the right side
Singh and Singh(2006) divided vowels into - ANSWER-tense, lax and neutral
Open syllables end in a/an - ANSWER-vowel
Rhotics are - ANSWER-vowels colored by a following /r/
