Q

What is the encoding process?

A

A mental and psychological process whereby cerebral commands of the speaker are sent to the vocal organs which are involved in speech transmission, and these organs, in turn, transmit speech in the form of sound waves through the air.

Q

What is phonetics?

A

the scientific study of the way speech sounds are produced by our vocal organs, the way they are perceived by listeners, and the way different sounds are combined into syllables, words and sentences

Q

Is speech the primary function of speech organs?

A

No. It is an overlaid secondary function. For example, the basic function of the lungs is respiration and the basic function of the larynx is to protect the breathing apparatus by preventing food from entering the lungs

Q

What does it mean to say that the glottis is in vibration?

A

the edges of the vocal folds are touching each other causing vibration in the glottis. During this process, the air passes between the vocal folds in a series of rapid, tiny puffs producing voiced sounds such as /b/, /d/ and /g/ and so on. This vibration in the vocal folds is what is commonly known as phonation

64
Q

What happens when the velum is raised?

A

the only escape for the air is through the mouth, resulting in the production of oral sounds only

65
Q

what happens when the velum is lowered?

A

air can escape through mouth and nose

66
Q

what happens when the velum is lowered and the oral passage is closed?

A

air escapes through the nasal cavity and consequently nasal sounds are produced like /m/ /n/ and /ŋ/

67
Q

Give an example of a language where nasalized sounds are produced when the velum is lowered and the oral passage is not closed?

A

In Hindi- nasalized sounds such as /ha:/

68
Q

What is there said to be in speech when the velum is raised?

A

a velic closure, and during a velic closure, velar sounds are articulated

69
Q

A

An egressive pulmonic airstream is caused when the air is exhaled.

75
Q

80
Q

Task Question 1i: What is commonly called the soft palate?

A

The velum is commonly called the soft palate.

81
Q

Task Question 2. What role does the glottis play in the production of speech?

A

The open, closed and intermediary states of the glottis play a vital role in the production of speech as these allow the production of different sounds. When the glottis is open (i.e. the vocal folds are spread far apart) as in normal breathing, voiceless sounds are produced (nil phonation). When the glottis is closed, the glottal stop can be produced. When the glottis is narrow, i.e. the vocal folds are pulled close together, but not so close as to create vibration, fricatives such as the glottal fricative /h/ are produced as well as whispers. When the glottis is in vibration, i.e. when the vocal folds are held together tightly, at the right tension so that the vocal folds are touching each other, the vocal folds are set in vibration, opening and closing rapidly as rapid tiny puffs of air push through the glottis. When the glottis is in vibration, voiced sounds are produced, e.g. /b/ and /g/.

82
Q

What is the difference between voice and speech?

A

voice does not always equate to speech, for example an infant crying is not speech, it is a vocalisation. Specifically, speech is the oral expression of thoughts and ideas which alter the basic tone of voice into specific identifiable sounds

83
Q

What happens to the diaphragm when we inhale?

A

the diaphragm contracts and expands vertically, lifting ribcage and allowing the lungs to fill with air

84
Q

What happens to the diaphragm when we exhale?

A

the diaphragm and ribcage relax again , causing the lungs to remove C02 by breathing out (after inhalation)

85
Q

Describe the vocal folds

A

white ligaments of tissue that position opposite to each other in the larynx

86
Q

Where is the larynx located between?

A

the base of the tongue and the top of the passageway to the lungs, known as the trachea

87
Q

When are the vocal folds always open?

A

during speech so that we can breathe

88
Q

What is voice generated by?

A

airflow from the lungs (airstream)

89
Q

The Bernoulli effect

A

When it is time to speak, the pressure below the larynx increases, until it blows the vocal folds apart.
The vocal folds are first forced apart at the bottom, followed by the top
The pressure forces the air through the vocal folds, creating suction as we exhale
This suction pulls the vocal folds together at the bottom, followed by the top
When the air from the lungs blows past the vocal folds at a high speed, the vocal folds vibrate
In order to produce typical loud speech, the vocal folds and larynx must vibrate normally

90
Q

How is speech produced?

A

through coordinated muscle action in the head, throat, chest, mouth, nasal cavity and abdomen

91
Q

How long does speech development require?

A

years of practise

92
Q

What does a child learn to do during speech development?

A

regulate muscle action in the head, throat, chest, mouth, nasal cavity and abdomen to produce understandable speech

93
Q

What do we position in reference to permanent parts of our vocal tract such as the roof of our mouth?

A

the tongue, jaw, velum and lips- active articulators

94
Q

Is speech simple or complex?

A

complex

95
Q

Why is speech important?

A

plays a fundamental role in our everyday lives

96
Q

What is the fundamental difference between language and speech?

A

language is an abstract theoretical form of communication, which is not limited to spoken language, containing languages which use gestures for example. Contrastively, speech is a specific manifestation of language which is produced with the vocal tract. Language is something only humans have, but many animals use their vocal tracts to communicate.

97
Q

What distinguishes the field of phonetics from the field of phonology?

A

meaning, sounds themselves do not carry meaning, but the study of abstract categories of sound (i.e. in phonology) can carry meaning, and are not necessarily arbitrary

98
Q

What makes speech interactive?

A
  1. Supplemented with facial expressions, bodily expressions and movements
  2. We are hearing, seeing & producing speech, and we take turns & interrupt each other
  3. The encoder has an idea in mind and articulates it with their vocal tract
  4. The decoder (i.e. the recipient) hears the speech stream and analyses it into smaller parts
99
Q

What are sounds?

A

pressure waves that propagate through the air to our ears

100
Q

What causes sounds?

A

perturbation of air particles

101
Q

What do waves move through?

A

compression and rarefaction of air particles

102
Q

What is compression?

A

increase in an item’s density

103
Q

What is rarefaction?

A

decrease in an item’s density

104
Q

How do sound waves travel through the ears?

A
  1. Moving air hits ears, gets channelled through ears and subsequently hits eardrum
  2. This moving air then gets amplified in eardrum
  3. The little bones inside the ear get moved by the sound
  4. the bones stimulate the inner ear (the cochlea) that is full of fluid and little hairs
  5. The bones move the fluid which stimulates the hairs
  6. These hairs when they move trigger a neural impulse to our brain, and that is what we experience as sound
105
Q

Name the two acoustic characteristics that sound waves possess

A

an amplitude (loudness) & frequency (pitch)

106
Q

Why are sounds described as complex?

A

they often include bunch of waves on top of each other with lots of different frequencies and amplitudes of these different frequencies.
This complexity gives the voice a rich character

107
Q

What other group of species make sounds (“vocalisations”) with their vocal tracts?

A

vertebrates (animals with backbones) i.e., frogs, birds, etc

108
Q

Is speech most often ingressive or egressive?

A

egressive

109
Q

Give an example of an ingressive sound we make?

A

when sucking in air

110
Q

Explain the source & filter model of speech production

A
  1. Air pushed from lungs through the vocal folds housed in the larynx, the source of voice
  2. Air is filtered through the supra laryngeal vocal tract
  3. Out through mouth and nose
111
Q

Differences in pitch between men and women

A

Men tend to have lower pitch voices, women tend to have higher pitch voices

112
Q

What is the frequency of a lower pitch voice?

A

approx. 80-120 hz

113
Q

What is the frequency of a higher pitch voice?

A

approx 160-180 to 250 hz

114
Q

What does frequency refer to?

A

the number of opening and closings of vocal folds per second

115
Q

How do we control our pitch?

A

by controlling the tension of our vocal folds

116
Q

What cartilage controls pitch?

A

the arytenoid cartilage- we open and close the arytenoid cartilage to control pitch

117
Q

Where are the arytenoid cartilages placed?

A

at the back, mounted on the thyroid cartilage, slide along the thyroid cartilage, creating a gap between vocal folds (glottis)

A

the velum is closed and a sound is produced by the tongue touching the soft palate

126
Q

What does a uvular sound mean?

A

produced with the uvula, piece of flesh at the back of the throat that you gargle with

127
Q

What does a pharyngeal sound mean?

A

produced with the tube that is in the throat, above the larynx, i.e. the pharynx

128
Q

What does a glottal sound mean?

A

sound articulated at the glottis, i.e. the hole between the vocal folds

129
Q

Name two example of stop consonants

A

plosives and taps

130
Q

What is the three letter phrase that refers to how a sound is filtered?

A

manner of articulation

131
Q

What is the difference between a plosive and a tap?

A

plosives tap the air for a second but taps are like a stop, but quicker, much more rapid tap of the tongue

132
Q

When are nasal sounds produced?

A

when the velum is raised and the oral passage is closed

133
Q

What does it mean to say that a sound is nasal?

A

produced through nose

134
Q

What do trills and fricatives have in common?

A

they do not make a complete closure, they let a restricted amount of air through a small gap which creates turbulence

135
Q

Give two examples of resonant articulations

A

open approximation (approximants) and vowels

136
Q

How are resonant articulations filtered?

A

by moving the tongue and lips around in different ways and not impeding the air much in doing so, just changing the shape of oral cavity and throat

137
Q

What is a key problem with representing speech?

A

it is an ephemeral and time-bound phenomenon (Ogden, 2017) so it lacks permanency and difficult to transcribe

138
Q

Name two keys ways of representing speech?

A

phonetic transcription (IPA) and acoustic representation (oscillograms & spectrograms)

139
Q

What does it mean to transcribe phonetically?

A

transcribe sounds into written symbols

140
Q

What principle is used to create phonetic transcriptions?

A

alphabetic principle- one-to-one mapping of letter to sound

141
Q

What assumption is made with phonetic transcription and how do we get around this limitation?

A

that speech can be described by one sound (phoneme) at a time, like beads on a string
Resolve this by accepting that phonetic transcription is an idealisation or a “convenient fiction” (‘cat’, ‘kit’, ‘coot’)

142
Q

Give three reasons for why we cannot just transcribe into the English alphabet

A
  1. Goal is to represent the sounds in a stable unambiguous alphabet
  2. English is not spelt phonetically, e.g. 26 symbols for about 45 sounds, ‘plough’, ‘cough’, ‘although’
  3. We want a system that is consistent across different spoken languages
143
Q

What are the three main principles of the International Phonetic Alphabet (IPA) ?

A
  1. to transcribe only “linguistically significant” information, e.g. not people’s different voices caused by physical differences
  2. each symbol corresponds to a distinct segment or speech sound
  3. Devised to cover all speech sounds of spoken languages
144
Q

Name three segments included in the IPA

A

consonants- produced with constriction in the vocal tract
vowels- produced without constriction in the vocal tract
suprasegmentals- aspects of speech that persist over multiple segments, duration, loudness, tempo, etc.

145
Q

Name the full list of sections included in the IPA

A
  1. Consonants (pulmonic)
  2. Vowels
  3. Consonants (non-pulmonic)
  4. Other symbols
  5. Diacritics
  6. Suprasegmentals
146
Q

How can you visualise the sounds of speech?

A

turn on microphone to generate sounds into an electrical signal, and then save these sounds onto your computer, save onto an uncompressed .wav file

147
Q

What does an oscillogram display?

A

sound pressure (y-axis) over time (x-axis)

148
Q

What does a spectrogram display?

A

frequency (y-axis) over time (y-axis), and amplitude represented by darkness

149
Q

Name two ways of acoustically representing speech

A

oscillograms (waveforms) and spectrograms

150
Q

What does a periodic noise refer to?

A

repeated vocal fold vibration

151
Q

What does an aperiodic noise refer to?

A

irregular vocal fold vibration

152
Q

What does a transient sound mean?

A

inconsistent noise, i.e. random burst spike

153
Q

What does a continuous sound mean?

A

consistency in acoustic representation of sound

154
Q

What is the difference between phonetics and phonology?

A

phonetics is the study of the production of speech sounds whereas phonology is the study of the abstract categories of speech sounds and their meaning, sounds themselves do not carry meaning so phonetics does not study sound meaning at all

155
Q

Explain the process of speaking. Refer to the source and filter model.

A

A pulmonic airstream travels from lungs through to the larynx, the source of voice when we exhale before speech production, this air then is filtered in the supra laryngeal tract and is released through the mouth and nose where sound is articulated

156
Q

What are two different modes of phonation? Describe the positioning of the vocal folds in each.

A

One mode of phonation is voicing. Voicing occurs when the vocal folds are so close together that they touch each other, causing a suction when we exhale, so that the vocal folds open and close consecutively at a very past pace due to the build up and decrease of the air pressure behind the larynx (the Bernoulli effect). Another mode of phonation is whisper, occurring when the vocal folds are close together, but not so close together as to cause phonation. The air passes through a narrow constriction, causing a release of turbulent air.
