Section 1: Phonology & The Speech Sound System
Q1: Which of the following best defines the term "phonology" as it relates to reading
instruction?
A. The system of rules for representing speech sounds in print
B. The study of the speech sounds used in a language and their rules for combination
[CORRECT]
C. The ability to manipulate sounds in spoken words
D. The smallest unit of meaning in a language
Correct Answer: B
Rationale: Phonology is specifically the study of the sound system of a language,
including the inventory of sounds and the rules governing how they can be combined,
distinct from the written representation (orthography).
Q2: A teacher asks a student to describe what happens to their vocal cords when they
say the sound /z/. The student correctly identifies that the vocal cords vibrate. Which
feature of articulation is the student describing?
A. Place of articulation
B. Manner of articulation
C. Voicing [CORRECT]
D. Vowel height
Correct Answer: C
Rationale: Voicing refers to whether the vocal cords vibrate during the production of a
sound; /z/ is a voiced sound, whereas /s/ is unvoiced but produced at the same place
and manner.
Q3: When producing the phoneme /b/, the lips come together to stop the airflow. Which
place of articulation does this describe?
A. Labiodental
B. Bilabial [CORRECT]
,C. Alveolar
D. Velar
Correct Answer: B
Rationale: The term "bilabial" literally means "two lips," describing sounds like /p/, /b/,
and /m/ where both lips are used to obstruct the airflow.
Q4: Which of the following statements accurately describes the difference between a
phoneme and an allophone?
A. A phoneme is a variant sound, while an allophone is the smallest unit of meaning.
B. A phoneme changes the meaning of a word, while an allophone is a predictable
variation of a phoneme that does not change meaning. [CORRECT]
C. Allophones are written symbols, while phonemes are spoken sounds.
D. Phonemes are found only in vowels, while allophones are found only in consonants.
Correct Answer: B
Rationale: Phonemes are contrastive units (changing /p/ to /b/ changes "pat" to "bat"),
whereas allophones are slightly different pronunciations of the same phoneme that
depend on context (like the aspirated 'p' in "pin" vs. the unaspirated 'p' in "spin").
Q5: A speech therapist is working with a student on vowel production. She explains that
for the sound /i/ (as in "see"), the tongue is high in the mouth and pushed toward the
front. Which two dimensions of vowel classification is she describing?
A. Tense and lax
B. Frontness and height [CORRECT]
C. Roundedness and backness
D. Manner and place
Correct Answer: B
Rationale: Vowels are classified by the position of the tongue; specifically, how high or
low it is (height) and how far forward or back it is in the mouth (frontness/backness).
Q6: Which of the following consonant sounds is produced by forcing air through a
narrow opening, creating friction (turbulence)?
A. Stop
B. Nasal
C. Fricative [CORRECT]
D. Glide
Correct Answer: C
Rationale: Fricatives, such as /f/, /v/, /s/, and /z/, are produced by constricting the airflow
sufficiently to cause friction or a "hissing" sound.
, Q7: In English, the /k/ sound in "cat" and the /k/ sound in "school" are produced at
slightly different places in the mouth (velar vs. palatal). These two variations are best
described as:
A. Distinct phonemes
B. Minimal pairs
C. Allophones of the /k/ phoneme [CORRECT]
D. Dipthongs
Correct Answer: C
Rationale: Although they sound slightly different due to the surrounding vowels, English
speakers perceive them as the same sound; these positional variations are allophones
of the single phoneme /k/.
Q8: A student is struggling to distinguish between the words "ship" and "sip." This
indicates a difficulty with which manner of articulation?
A. Gliding vs. stopping
B. Frication vs. affrication
C. Narrowing the airflow (fricative) vs. stopping the airflow (affricate) [CORRECT]
D. Voicing vs. voiceless
Correct Answer: C
Rationale: The difference between "ship" (/ʃ/, a fricative) and "sip" (/s/, a fricative) is
subtle, but "chip" (/tʃ/, an affricate) involves a stop followed by a fricative. However, the
confusion here is often between the specific fricative sounds or the affricate /tʃ/ vs /ʃ/ or
/s/. In the context of LETRS, distinguishing specific consonant blends or manner
distinctions like stops vs. continuants is key. The most precise distractor analysis here
suggests the student is distinguishing between different types of friction or airflow
constriction. Correction: Actually, the confusion is usually between /ʃ/ and /s/ (both
fricatives) or /tʃ/ and /s/. Let's refine the question to focus on a clearer manner
distinction.
Refined Q8 for clarity: A student is struggling to produce the sound "ch" as in "chop."
The teacher notes the student is stopping the air completely rather than releasing it with
friction. This describes a struggle with:
A. Fricative production
B. Affricate production [CORRECT]
C. Nasal production
D. Glide production
Correct Answer: B
Rationale: Affricates (like /ch/ and /j/) are complex sounds that begin as a stop (air stops
completely) and are released as a fricative (friction).
Q9: Which of the following terms refers to the ability to hear and manipulate the larger
"chunks" of syllables and onsets and rimes within words?
