COMD 5070 Final Exam Guaranteed Success
1. The speech signal is

✔️ Neither invariant nor linear

(This indicates that the speech signal varies significantly across different contexts and conditions.)



2. When a listener simplifies the processing of the speech signal to smooth out superfluous variability, it
is called

✔️ Perceptual normalization

(This process helps listeners focus on the essential features of speech despite variability in production.)



3. One type of quantal perception that occurs as we listen to speech is called

✔️ Categorical perception

(This refers to the phenomenon where sounds are grouped into distinct categories, making it easier for
listeners to differentiate them.)



4. In duplex perception:

✔️ Syllable components are presented separately, but simultaneously, to each ear

(This concept demonstrates how the brain can integrate sound components from different sources.)



5. In the McGurk effect:

✔️ The place and/or manner of articulation is perceived to change

(This perceptual phenomenon occurs when conflicting visual and auditory components of speech lead
to a different perceived sound than either signal alone.)



6. Top-down processing in the perception of speech involves

✔️ Using contextual, linguistic, and cognitive cues

(This process allows listeners to interpret and understand speech based on prior knowledge and
context.)

, 7. Which speech perception theory has been criticized as being so vague that it is more of a philosophy
than a theory or model?

✔️ Motor theory

(Some critics argue that it lacks specificity and testability, which are important for scientific theories.)



8. Perceptual magnets:

✔️ Enhance differences between distinct phonemes

(This concept explains how certain phonemes are perceived as more similar to each other within their
categories.)



9. Cohort theory:

✔️ Based on the similarity of acoustic features of the beginning of words

(This theory suggests that listeners activate a set of possible words from the initial sounds heard,
narrowing them down as more of the word is detected.)



10. Research with infants has shown that

✔️ Dominant language exposure gradually decreases discrimination of non-native speech features

(This indicates that early exposure to a particular language can affect the ability to differentiate
sounds from other languages.)



11. What is science?

✔️ A refinement of everyday thinking

(Science refines our understanding and approach to the world through structured inquiry.)



12. What are the 4 features of the scientific method?

✔️ Empirical, deterministic, predictive, parsimonious

(These features provide a framework for scientific inquiry.)



13. A nonlinear increase in frequency as you go from low to high is called

✔️ Semitone
