The source function is primarily ____ of the transfer function.

A

Independent

109
Q

The source function is determined by the ___.

A

Vocal folds

110
Q

The transfer function is determined by the ___.

A

Vocal tract

111
Q
  1. When you change the vocal folds, or source, what 2 things are different?
  2. What 2 things stay the same?
A
  1. Fundamental frequency and spacing btwn the harmonics

2. Resonance, the formant frequencies

112
Q

Name the type of vowel and placement of /i/

A

High, Font, unrounded vowel

113
Q

Name the type of vowel and placement of /a/

A

low, back, unrounded vowel

114
Q

Name the type of vowel and placement of /u/

A

high, back rounded vowel

115
Q

/i/ is produced with high frequency formants, in other words, the vocal tract is resonating at high frequencies. Why does this happen?

A

bc the oral cavity has been made smaller by the speaker, putting his tongue to the front of the oral cavity and high up in the oral cavity
-the mass of the tongue occupies most of the oral cavity that leaves a small amount of air to vibrate

116
Q

Vowel /i/ has a high 1 and 2 and low 3

A
  • high F3 and F3

* Low F1

117
Q

What is the primary muscle responsible for he tongue forming the shape, up and forward creating the sound /i/?

What nerve innervates this muscle?

A

Genioglossal

innervated by the hypoglossal nerve (XII)

118
Q

Name 3 ways of visually displaying sound.

A
  1. Line spectrum
  2. wave form
  3. spectrogram
119
Q

What does a spectrogram do?

A

Displays speech

-frequency shown on the ordinate (Y axis ^) time on the abscissa (x axis )

120
Q

What are some differences between spectrograms and output spectrums ?

A
  1. Time is represented in spectrograms but is not shown in output or line spectrums
  2. spectrograms dont show any information about individual harmonics
121
Q

For /a/ the oral cavity is 1 and the pharyngeal cavity is 2 than for /i/, so there is a 3 F_4_.

A
  1. Larger
  2. Smaller
  3. higher F1
122
Q

For /a/ we enlarge the oral cavity in what 2 ways?

A
  1. lower the tongue by lowering the jaw

2. actively lowering the tongue

123
Q

Name 2 muscles involved in creating the /a/ sound.

A
  1. Anterior belly of the digastric muscle innervated by the trigeminal nerve (V)
  2. Hyoglossus muscle innervated by the hypoglossal nerve (XII)
124
Q

What muscle controls the jaw when creating the /a/ sound?

what is this muscles innervation?

A

Anterior belly of the digastric muscle innervated by the trigeminal nerve (V)

125
Q

When creating the sound /a/ what muscle acts to depress the tongue and enlarge the oral cavity?

What nerve innervates this muscle?

A

Hyoglossus innervated by the hypoglossal nerve (XII)

126
Q

What muscles are involved in creating the /u/ sound?

A
  1. styloglossus muscle innvervated by the hypoglossal nerve (XII)
  2. Obicularis oris muscle innervated by the facial nerve (VII)
127
Q

When creating the sound /u/, what muscle is used to elevate the tongue near the roof of the mouth where the hard and soft palate join?

What is this muscle innervated by?

A

Styloglossus innervated by the hypoglossal nerve (XII)

128
Q

When creating the /u/ sound, what muscle is resonsible for rounding and protruding the lips?

What is this muscle innervated by?

A

obicularis oris muscle innervated by the facial nerve (VII)

129
Q

When we round and protrude the lips this elongates the 1 cavity. This results in 2 of all formant frequencies.

*true of /u/ sound

A
  1. oral cavity

2. lowering all formants frequencies

130
Q

The exact formant or resonate frequencies depend on the individual people in what 3 ways?

*Variable formants depend on…

A
  1. The size of their overall vocal tracts
  2. the size of different parts of individual vocal tracts, tongues, lips, throat,
  3. People articulate slightly differently, due to their dialects and habits of speaking
131
Q

Name the components represented on the vowel quadrilateral.

A
  1. Tongue height (high to low)
  2. Tongue Advancement (Back to front)
  3. Pharynx open (wide or narrow)
  4. Oral Cavity (short or long)
132
Q

What is the name of the diagram that depicts a schematic representation of vowel placement in the mouth?

A

vowel quadrilateral

133
Q

The vowel quadrilateral represents the areas in the oral cavity where _____ is made.

A

Constriction

134
Q
  1. What is a lax vowel?

2. where do you find these vowels?

A
  1. less extreme tongue positions and shorter duration

2. found in closed syllables such as sit, set, sat

135
Q
  1. What is a tense vowel?

2. where do you find these vowels?

A
  1. Vowels with the most extreme tongue positions and the longest duration
  2. found in open syllables such as see, say, so, sue
136
Q

What 2 categories are tense vowels divided into?

A
  1. Whether or not the vocal tract stays constant though out the vowels production
  2. if it changes some what to make a diphthong
137
Q

What is a diphthong?

Name english diphthongs.

A

Diphthongs are vowels that have changes in resonance. They are tense vowels that have changing vocal tract dugong production.

/ au / as in “how’
/ ou / as in “Joe”
- Diphthongs ending in / u / involve tongue movement back and up

/ ai / as in “like”
/ oi / as in “toy”
/ ei / as in “train”
-Diphthongs ending in /i/ involve the tongue moving forward and up

138
Q

The Diphthongs that end in /i/ involve the tongue moving ______.

A

involve the tongue moving forward and up

139
Q

The Diphthongs that end in /u/ involve the tongue moving ______.

A

involve tongue movement back and up

140
Q

People with hearing losses have trouble perceiving and producing ____ and _____.

A

Vowels and diphthongs
