COMD 5070 EXAM 2 Updated 2024/w/ - ANSWER-______ production is characterized by lip rounding and an elevated
tongue dorsum (back), and is similar to /u/ articulation
1/12 - ANSWER-semitone scaling:
-using semitones corresponds more closely to our pitch perception (non-linear)
-a semitone is always _____ of an octave
-S.D. in Hz is hard to compare across males and females, so we use semitone standard
deviation to make values comparable for high or low mean F0
12 - ANSWER-a typical voice has a slope value of _____ dB per octave, which reflects
how sharply the harmonic amplitudes drop off from the F0
150-200 - ANSWER-a healthy voice has an average airflow of ____-______ cc/sec
e.g. if 1 liter of air is used and phonation lasts 5 seconds, the average airflow is 1/5
L/sec, or 0.2 L/sec
25, 100 - ANSWER-voiceless VOT is typically above ______ ms (ms before VF
oscillation commences)
-may be as much as ______ ms
30 - ANSWER-a representative semitone standard deviation (STSD) requires about
_______ seconds of continuous speech
-remember that F0 typically rises with SPL
5 ms - ANSWER-if F0 is 200 Hz, what is its period in ms?
5-7, 15-20 - ANSWER-Psub values typical for:
-normal speech/conversation: ____ cmH2O
-loud speech/shouting: ____ cmH2O
-clear association between Psub and SPL
50-150, 1/10 - ANSWER-the stop gap closure is typically ___-______ ms or ____/___
of a second in duration
6, 12, 18 - ANSWER-on a laryngeal source spectrum, showing F0 and harmonics, the
F0 is the first and tallest harmonic component
-_____ dB/octave is associated with a bright, resonant voice
-_____ dB/octave is associated with a typical voice
-______ dB/octave is associated with a thin, weak voice
, abdomen, ribcage - ANSWER-during singing, there is some degree of independence
between the ______ and ______ allowing the singer greater control of their voice
affricate - ANSWER-a/n __________ is a:
-stop
-then a noisy release
-frication that is longer than a stop burst
-shorter than a fricative
affricates - ANSWER-fairly brief stop and frication interval is associated with _________
age, speech rate, phonetic context - ANSWER-influences on VOT:
1. ______
2. ______ ______
3. _____ _______
airflow rate/volume velocity - ANSWER-cc/s, L/s, gallons/minute, are all units that can
be used to represent _______ _____/______ _______
alaryngeal speech - ANSWER-some people who get cancer of the larynx have to get a
laryngectomy, and must learn to use ________ ___________ in which the esophageal
sphincter vibrates for the production of voice
-the F0 can be as low as 30 Hz
aperiodic, nearly periodic - ANSWER-noise is _______ in its waveform, while the
human voice is ______ ________
aspiration - ANSWER-_________ may follow a voiceless stop
-only seen in CV contexts
-vocal folds begin to adduct
-moving air become turbulent at the glottis
-generates noise, although weak in amplitude/energy
aspiration - ANSWER-in an aspirated voiceless stop, the duration of the frication interval
+ __________ is equivalent to the VOT
because the VF are stretched very tightly for falsetto, requiring more pressure to
oscillate them - ANSWER-Psub is lower for pulse register and higher for falsetto, why
might this be?
cmH2O - ANSWER-what is the pressure unit of measurement used in speech
research?
decreases - ANSWER-as frequency increases, the duration of each cycle (period)
_________
