Q

Why are minimal contrasts useful to linguists?

A

Minimal contrasts are useful to linguists trying to identify individual phonemes of a language. They can ask themselves: if I change or remove this smallest unit of sound, does the meaning of the word* change?

Q

How could the /t/ sound be an allophone?

A

For example:
It has multiple allophones.

While they are different,
we perceive them both as /t/.

“aspirated /t/” where /t/ = [tʰ]
“tap” or “flap” where /t/ = [ɾ]

Q

What are phonetic symbols?

A

symbols that represent speech sounds
-one-to-one correspondence: one symbol = one sound
-phonetic symbols are different from orthographic symbols
- they are not flexible

“shoe” and “shoo”are transcribed as /ʃu/
31
Q

Define
articulation, articulate, articulators:

A

articulation: production of speech sounds

articulate: to produce a speech sound

articulators: the parts of our speech apparatus that create speech sounds (i.e., the teeth, lips, jaw, velum, tongue)

32
Q

Define Misarticulations and Coarticulation:

A

misarticulations: error productions and mispronunciations, not necessarily associated with a speech sounds disorder

coarticulation: some overlap of speech gestures. When the articulators are simultaneously completing one sound while preparing the next sound

33
Q

What is speech?

A

A mode of language expression based on sounds emitted through mouth and nose. It includes:
-patterns of movement of speech organs
-patterns of acoustic vibrations

34
Q

What are other non-speech forms of communication? (4)

A

-Writing
-Sign language
-Tadoma
-lip reading

35
Q

What is a dialect?

A

A variation of speech or language based on geographical area, native-language background, and social and/or ethnic group membership.

36
Q

What is the Received Pronunciation (RP)?

A

The typical South British accent (upper and middle class)

37
Q

What is General American (GA)?

A

Two-thirds of American population
This is the dialect largely taught to ESL learners

38
Q

What is an idiolect?

A

As compared to a dialect, a broad general term for
a lot of people, an idiolect is an individual speaker’s
personal pattern of language use.

39
Q

What are registers?

A

Continuum of speaking styles from formal to informal.
Registers vary depending on the social situation.

40
Q

Registers can change:

A

pronunciation. The more formal the register, the more precise the articulatory patterns tend to get.

Informal <—> Formal

Casual Speech <—> Citation Form

Yo <—> How do you do?
Dontcha <—> don’t you
friends/family <—> bosses/officials/professionals/elders etc

41
Q

What is the invariance problem? (3)

A

-Articulation of phonemes varies across speakers and also within individual speakers
-We say things differently depending on context (listener, environment, register, etc.)
-Lack of consistency in speech production

42
Q

What are word shapes?

A

The structural combinations of consonants and vowels within a word
C = consonant
Consonants can be described initial, medial, or final in a word

    V = vowel
43
Q

What are consonant clusters?

A

two or more consonants in a row

	“stop” =/stɑp/ = CCVC
44
Q

What are the five anatomical processes for speech production?

A

Respiratory (Airflow)
Phonatory (Vocal fold vibration)
Resonatory (Shaping the sound)
Oro-nasal (Mouth or nose airflow)
Articulatory (Movement of the articulators)

45
Q

Describe Respiration:

A

Airflow system for breathing that
brings in oxygen and removes
carbon dioxide

46
Q

Describe inhalation:

A

The diaphragm contracts, which increases thoracic space (chest area) and causes rib cage to expand

As the rib cage expands, lungs, which are lightly connected to rib cage, expand and air pressure in lungs decreases

Outside air moves from high pressure area (atmosphere) to low pressure area (into lungs)

47
Q

Describe exhalation:

A

Exhalation is a passive process where diaphragm relaxes and moves upward to reduce thoracic (chest) space, forcing air out of the lungs.
English speech is produced on the exhale (expiratory air).
Some languages produce some sounds on the inhale (inspiratory air)
Gaelic gasp? Mummers?
Speech requires controlling and metering out the release of airflow, and some disorders cause poor coordination of this.
Time speaking is usually about 10% inhale and 90% exhale.

48
Q

Describe the larynx in phonatory:

A

Complex structure of bone, cartilage, and muscle
above the trachea (windpipe) that contains the vocal folds.

49
Q

Describe the vocal folds in phonatory:

A

Pair of elastic muscle fibers that can be opened, closed tightly, or approximate (come close)
each other.

50
Q

Describe phonation:

A

The vocal folds take advantage of the Bernoulli principle, an aerodynamic effect where airstream from the lungs (pulmonic) opens vocal folds and decreased air pressure in trachea closes vocal folds in a rapid open/close vibratory cycle. It creates a buzzing noise.

Phonation for voiced sounds comes from vocal fold vibration.

Speech sounds may be voiceless or voiced depending on the presence/absence of vocal fold vibration.

51
Q

What does abducted VF mean?

A

open vocal folds
Breathing and voiceless sounds

52
Q

What occurs during approximated VF?

A

come close to each other and
vibrate, or “buzz” to create a sound

53
Q

What occurs during adducted VF?

A

tightly closed vocal folds, for swallowing or lifting
heavy objects

54
Q

What is resonance?

A

Shaping the sound
When we change the shape of the vocal tract we alter the shape of passageway for airflow.

55
Q

What is amplifying?

A

strengthening certain frequencies or reinforcing parts of the sound

56
Q

What is attenuation?

A

weakening certain frequencies or dampening parts of the sound

57
Q

What is Oro-nasal sounds?

A

(mouth/nose) Sounds which escape through the mouth or nose

58
Q

What changes the airflow between oral and nasal?

A

Velum

59
Q

What is the velum?

A

The velum (soft palate) raises and lowers to direct airflow. It’s like a valve.

60
Q

How are oral sounds produced?

A

Airflow only travels through the mouth because the velum is raised to prevent airflow through the nose (see image, next slide)

61
Q

How are nasal sounds produced?

A

Airflow travels through the nose because the velum is lowered, which allows access to the nasal passages

62
Q

What is the difference between these two images?

A

On the left, velum is a raise state with airflow blocked from entering nasal cavity

On the right, velum is a relax state with air flowing into nasal cavity

63
Q

When does nasality occur and does not occur?

A

Occurs with a lowered velum, so those muscles in a relaxed state or cannot fully articulate with walls of nasopharynx.

With a raised velum, the velum touches back and side walls of pharynx and blocks air from entering the nasal cavity. Breathing can only be done through mouth.

64
Q

Most sounds in General North American English are oral or nasal?

A

oral

65
Q

/m, n, ŋ/ are:

A

m, n, ŋ/ are nasal consonants, technically “nasal stops”

66
Q

What is hypernasality?

A

Too much airflow through the nose

67
Q

What is hyponasality?

A

not enough airflow through the nose

68
Q

What are the 4 main anatomical structures used to produce speech sounds?

A

Lips: Active articulators that spread, round (pucker), and tense
Upper teeth: Passive articulator
Lower teeth: Active articulator
Tongue: The primary active articulator for finely coordinated movement. A highly muscular organ

69
Q

Describe the alveolar ridge?

A

Passive articulator consisting of bony ridge behind upper incisors

70
Q

Describe the hard palate:

A

Passive articulator

71
Q

Describe velum:

A

Active articulator that directs airflow

72
Q

Describe the Uvula:

A

Back portion of velum

73
Q

Describe the Pharynx:

A

Passageway between larynx and oral/nasal cavities

74
Q

Describe the Epiglottis:

A

Cartilage that protects the airway
