The Three Phonetics: Articulation, Propagation, and Recognition

Which branch of phonetics primarily investigates the physical movements and positions of the tongue, lips, teeth, and palate during speech production?

• Articulatory Phonetics

• Acoustic Phonetics

• Auditory Phonetics

• Phonology

In the study of phonetics, which branch measures frequency, amplitude, and duration of sounds using instruments such as spectrographs to analyze sound waves traveling through air?

• Articulatory Phonetics

• Acoustic Phonetics

• Auditory Phonetics

Which statement best captures how the three branches of phonetics interconnect in understanding speech sounds?

• Articulatory processes create sounds that become acoustic signals, which listeners perceive and process auditorily.

• Acoustic analysis determines how the brain moves articulators to form words, then articulatory phonetics interprets auditory feedback.

• Auditory phonetics produces sound waves that articulatory phonetics records, and acoustic phonetics trains perception.

• Articulatory phonetics measures spectrograms, acoustic phonetics trains the ear, and auditory phonetics positions the vocal organs.

Which pair of organs primarily provides the airstream necessary for speech, acting as the power source for voiced sounds?

• Larynx and vocal folds

• Lungs and diaphragm

• Tongue and lips

• Teeth and hard palate

In English phonetics, what is the usual initiation mechanism that generates airflow for speech? Choose the best description.

• Pulmonic egressive: air pushed out from the lungs by diaphragm contraction

• Glottalic ingressive: air drawn in through the glottis by vocal fold abduction

• Velaric egressive: air compressed in the oral cavity by tongue root movement

• Pulmonic ingressive: air pulled into the lungs during articulation

What articulatory change distinguishes /z/ from /s/ when all other articulatory settings remain the same?

• Tongue position shifts from alveolar ridge to velum

• Lip rounding increases for /z/

• Phonation: vocal folds vibrate for /z/ but not for /s/

• Airstream changes from pulmonic to velaric for /z/

Refer to the labeled diagram of the organs of speech. Which label identifies the location of the vocal folds (glottis), central to phonation?

• Alveolar ridge

• Larynx

• Soft palate (velum)

• Lower jaw

Which set lists the three fundamental parameters used to classify English consonants as presented: choose the best trio.

• Manner of articulation, place of articulation, voicing

• Stress, intonation, rhythm

• Tongue height, lip rounding, vowel length

• Syllable structure, word frequency, spelling

According to the definitions provided, which description best matches a fricative?

• Complete closure followed by release of the airstream

• Oral closure with air flowing through the nasal cavity

• Narrow constriction creating turbulent airflow

• Slight narrowing without turbulence

Select the correct three-parameter description for /t/ based on the practical examples.

• Voiceless alveolar stop

• Voiced alveolar stop

• Voiceless bilabial stop

• Voiced velar stop
