Consonants & Vowels

Question 1

Consonants /w/ and /j/ are liquids. T/F

Answer 1

False - Approximants (Glides or Semivowels)

Question 2

An affricate is a combination of a stop and a fricative. T/F

Answer 2

True

Question 3

Vowel sounds can be classified based on the position of the tongue in the mouth, while consonant sounds are classified based on the manner of articulation and place of articulation. T/F

Answer 3

True

Question 4

The vowel quadrilateral is exclusively used in phonetic analysis and has no practical applications in language learning or speech therapy. T/F

Answer 4

False

Question 5

Vowels are speech sounds produced without any significant constriction or blockage in the vocal tract. (Open vocal tract)

Answer 5

True

Question 6

Formants are resonant frequencies in the vocal tract that amplify certain frequencies of sound. T/F

Answer 6

True

Question 7

The second formant (F2) frequency tends to be higher for front vowels compared to back vowels. T/F

Answer 7

T

Question 8

The first formant (F1) tends to be higher in frequency for high vowels compared to low vowels. T/F

Answer 8

T

Question 9

The second formant (F2) primarily determines the backness or frontness of a vowel. T/F

Answer 9

True

Question 10

The vowel quadrilateral is a static representation and does not account for dynamic changes in vowel articulation. T/F

Answer 10

False

Question 11

Vowel sounds located towards the front of the vowel quadrilateral are typically produced with the tongue positioned more forward in the mouth. T/F

Answer 11

True

Question 12

Vowels positioned closer to the center of the vowel quadrilateral are central vowels

Answer 12

True

Question 13

Spectrograms are primarily used to analyze vowel sounds and are less effective for studying consonant articulation.

Answer 13

False

Question 14

Spectrograms of consonants typically show clear distinctions between voiced and voiceless sounds. T/F

Answer 14

True

Question 15

Fricative consonants are produced by creating friction or turbulent airflow through a narrow constriction in the vocal tract. T/F

Answer 15

True

Question 16

Spectrograms are unable to capture temporal characteristics, such as the onset and release of consonant sounds.

Answer 16

False - they can

Question 17

In a waveform what is plotted on the x and y axis

Answer 17

X - Time
Y - amplitude

Question 18

Spectrogram: Label x/y axis and intensity

Answer 18

X - time
Y - Frequency
Intensity - how strong the frequency of a sound wave is at a point in time

Question 19

Voiced consonants are produced with vibration of the vocal cords, similar to vowel sounds, while voiceless consonants are produced without vocal cord vibration.

Answer 19

True

Question 20

Consonants are produced with a complete closure or constriction in the vocal tract, whereas vowels are produced with a relatively open vocal tract.

Answer 20

True

Question 21

Vowels are typically longer in duration compared to consonants, as they form the core of syllables in many languages. T/F

Answer 21

True

Question 22

Spectrogram provides more detailed information about the frequency content of a sound compared to a waveform T/F

Answer 22

True

Question 23

T/F Obstruent’s are produced by restricting airflow. Sound at constriction moves forward and backward

Answer 23

True

Question 24

Glides, Fricatives and Affricates are obstruents

Answer 24

False - stops instead of glides

Question 25

The 3 places of articulation of oral stops are bilabial, alveolar and dorsal

Answer 25

True

Question 26

Are there an aspiration interval in voiced stops

Answer 26

No only in voiceless stops but both have a frication interval

Question 27

Define an affricate

Answer 27

Combination of stop and fricative

Question 28

Affricates involve complete constriction, followed by a noise burst long frication interval and then an aspiration interval

Answer 28

True

Question 29

The vowel quadrilateral is exclusively used in phonetic analysis and has no practical applications in language learning or speech therapy.

Answer 29

False
