what is fundamental frequency? - ANS--The lowest frequency of a periodic wave. The first
harmonic.
- physical measurement
can a complex wave still be periodic? - ANS-yes simple or complex it dose not matter because it
can still repeat
what does it mean to be "nearly periodic"? - ANS-repeating pattern but not perfectly periodic.
what is the period of a sound? - ANS-a signal or repeating sound
what does Hz mean? - ANS-1 cycle per second
Why would a SLP would be interested in measurements of fundamental frequency? - ANS-can
help with treatments
when the vocal folds vibrate faster/slower, what is the perceived change in a persons voice?
(e.g., is it louder, softer, higher, or lower in pitch) - ANS-- The faster the vocal folds vibrate, the
higher the pitch. Extremely slow vocal fold vibration is about 60 vibrations per second and
produces a low pitch
modal register also called
a. chest voice
b. vocal fry - ANS-a. chest coice
modal register is typically a
a. crackly quality voice
b. typical speaking voice - ANS-b. typical socking voice
modal register has what type of range
a. mid range singing
b. very low FO range - ANS-a. mid range singing
modal register has a wide dynamic range? (T/F) - ANS-true
plus register also known as - ANS-vocal fry
pulse register have a crackly quality (T/F) - ANS-true
, pulse register occurs at a high or low FO range? - ANS-very low FO range
plus register vocal fold do not relatively stick? (T/F) - ANS-false they DO relatively stick
puls registar has a very high pitch and loudness range? (T/F) - ANS-false very limited pitch and
loudness range
falsetto vocal folds are stretched tightly? (T/F) - ANS-true
falsetto is at the high end of F0? (T/F) - ANS-true
falsetto covers the vocal folds oscillates vertically? - ANS-false medially
falsetto has lots of involvement of muscles in vibration? (T/F) - ANS-false it has little to ni
movement
falsetto oscillation alomost sunisodial? (T/F) - ANS-true
what does it mean if a person has a lack of variability in their fundamental frequency across a
reading passage (how would they sound? - ANS-their voice will sound monotone (low
variability)and their muscle movements will not be able to change their muscle movements to
change their speech.
People change ff depending on the type of topics. they will use reading passages to compare
over time when the person reads the passage again
their formants don't change and FF is the same
What does standard deviation of fundamental frequency tell you? - ANS-is a measurement of
average change in value
in the case of ff, standard deviation can tell you how much a speaker changes their rate of vocal
fold vibration/ expression to their voice across words
ex: Low standard deviation= monotone voice
Describe how the way people read a passage alter their fundamental frequency - what are
some behavioral factors that affect fundamental frequency? - ANS-their voice will sound
monotone (low variability)and their muscle movements will not be able to change their muscle
movements to change their speech.
