The frequency of the first formant is determined by the volume of the
_______ cavity. - ✔✔The frequency of the first formant is determined by the
volume of the pharyngeal cavity
Explain how tongue/jaw height has an influence on the volume of this
cavity. - ✔✔· If the vocal tract is tightly constricted as in a high vowel the
pharyngeal cavity is large.
o Tongue root/body are pulled clear of pharyngeal space.
If the jaw/tongue are low the tongue root is forced back into the
pharyngeal cavity, creating a smaller volume
State the relationship between tongue/jaw height and F1 frequency. Give
examples of two vowels with a high F1 frequency and two vowels with a
1

,low F1 frequency. - ✔✔· When the volume of the pharyngeal cavity is small
it resonated at high frequency.
· Therefore, a low tongue/jaw position is associated with F1 frequency
The lower the vowel the higher the F1 frequency
The frequency of the second formant is determined by the volume of the
________ cavity (which is the space ____________________________). -
✔✔oral or front cavity
which is the space in front of the point of maximum constriction between
the tongue and the palate
Explain how anterior/posterior placement of the tongue affects the volume
of the oral or front cavity - ✔✔· When the cavity is small, it resonates at a
high frequency
Therefore, a more anterior tongue position is associated with a higher F2
frequency

, State the relationship between tongue backness and F2 frequency. Give
examples of two vowels with a high F2 frequency and two vowels with a
low F2 frequency. - ✔✔· Low front vowels have a lower F2 frequency then
high front vowels.
· The tongue body is displaced back into the pharynx in low vowels
o This increases the volume of the front cavity.
· If the front cavity is smaller F2 is larger.
. How does lip rounding influence F2 frequency? - ✔✔· Rounding of the
lips makes the front cavity longer and F2 even lower.
. Give two reasons nasal sounds have a lower intensity than vowels. -
✔✔Nasal cavities are lined with mucous which absorbs sounds.
The oral cavity is occluded during nasal production, so some aire gets
trapped in the oral cavity and doesn't resonate through the nasal cavity.
. What is the nasal murmur? - ✔✔· A sound that is generated because of the
extra resonances caused by sound being filtered through both the sides of
the nasal cavity and the nostrils.
