Q

Q

What is a plosive?

23
Q

What is the usual differentiation between stop and nasal?

A

The term stop is almost always used to indicate an oral stop, while the term nasal is almost always used to indicate a nasal stop, though both can be classified as stops, and though stop is commonly used to imply complete stoppage of airflow through both the nose and mouth.

24
Q

What is a fricative?

A

Close approximation of two articulators so that the airstream is partially obstructed and turbulent airflow is produced.

25
Q

What is a sibilant?

A

A fricative or affricate made by directing a stream of air with the tongue towards the sharp edge of the teeth, which are held close together, making a higher-pitched and more obvious hiss.

26
Q

What is a strident?

A

A fricative or affricate made directly with the tongue or lips etc. and the place of contact in the mouth. All sibilants are stridents, but stridents that are created without the involvement of the teeth make a lower sound and are not sibilants.

27
Q

What is an approximant?

A

A gesture in which one articulator is close to another, but without the vocal tract being narrowed to such an extent that a turbulent airstream would be produced.

28
Q

What is a lateral?

A

An obstruction of the airstream at a point along the center of the oral tract with incomplete closure between one or both sides of the tongue and the roof of the mouth. Called approximants because there is no stoppage of air and no fricative noises.

29
Q

What is an affricate?

A

The combination of a stop immediately followed by a fricative.

30
Q

What is an apical articulation?

A

An articulation made with the tip of the tongue.

31
Q

What is a laminal articulation?

A

An articulation made with the blade of the tongue.

32
Q

What are the differences between consonants, vowels and glides?

A

Consonants are produced with substantial constriction in vocal tract, have less acoustic energy than vowels and may involve intervals of silence or noise. Vowels are produced with less constriction and have more acoustic energy than consonants. Glides are vowel-like consonants, being more constricted than vowels while having lower energy.

33
Q

How are consonants described?

A

Voicing, place of articulation, and manner of articulation.

34
Q

What is the active articulator?

A

The part of the vocal tract that moves to create an articulation.

35
Q

What is a passive articulator?

A

The part of the vocal tract that does not move to create an articulation.

36
Q

What are the articulators of a bilabial?

A

Passive: upper lip, Active: lower lip

37
Q

What are the articulators of a labiodental?

A

Passive: upper teeth, Active: lower lip

38
Q

What are the articulators of a dental?

A

Passive: upper teeth, Active: tongue tip/blade

39
Q

What are the articulators of an alveolar?

A

Passive: alveolar ridge, Active: tongue tip/blade

40
Q

What are the articulators of a post-alveolar?

A

Passive: back of alveolar ridge, Active: tongue blade

41
Q

What are the articulators of a palatal?

A

Passive: hard palate, Active: front of tongue

42
Q

What are the articulators of a velar?

A

Passive: soft palate, Active: back of tongue

43
Q

What are the articulators of a uvular?

A

Passive: uvula, Active: back of tongue

44
Q

What are the articulators of a glottal?

A

Passive: glottis, Active: larynx

45
Q

What is labialisation?

A

The co-articulation of the vowel u with another articulation.

46
Q

What is palatalisation?

A

The co-articulation of the vowel i with another articulation.

47
Q

What is velarisation?

A

The co-articulation of the vowel (unrounded o) with another articulation.

48
Q

What is pharyngealisation?

A

The co-articulation of the vowel (low back unrounded) with another articulation.

49
Q

What are formants?

A

Characteristic overtones of vowel sounds.

50
Q

What is intonation?

A

The pitch pattern in a sentence.

51
Q

What is the difference between voiced and voiceless sounds?

A

Voiced sounds are produced when the vocal folds are vibrating, while voiceless sounds are produced when the vocal folds are apart.

52
Q

What makes up the vocal tract?

A

The air passages above the larynx, the oral tract and the nasal tract.

53
Q

What are the four main components of the speech mechanism?

A

The oro-nasal process, the articulatory process, the phonation process, and the airstream process.

54
Q

What are front vowels?

A

Vowels where the highest part of the tongue is in the front of the mouth.

55
Q

What are back vowels?

A

Vowels where the tongue is close to the back surface of the vocal tract.

56
Q

What is the difference between unrounded and rounded vowels?

A

Rounded vowels use rounded lips, unrounded vowels do not.
