Speech: Redundancy of Acoustic Information, Top-down Processes and Sinewave Speech

Question 1 of 3

1

The redundancy inherent in speech signal has what results?

Select one of the following:

  • (1) Lessens the effect of interfering stimuli
    (2) Allows listener to compensate for distortions in the signal
    (3) Reduces impact of individual speaker differences

  • (1) Lessens the effect of interfering stimuli
    (2) Allows listener to compensate for distortions in the signal
    (3) Increases impact of individual speaker differences

Question 2 of 3

1

Give an example of research into top-down processing of auditory stimuli and what was found.

Select one of the following:

  • Miller and Licklider (1950) recordings of word lists regularly interrupted, words perceived more natural when interrupted by noise, then when interrupted by silence (picket fence effect)

  • Miller and Licklider (1950) recordings of word lists regularly interrupted, words perceived more natural when interrupted by silence, then when interrupted by noise (picket fence effect)

  • Miller and Licklider (1950) recordings of sound sequences regularly interrupted, sounds perceived more natural when interrupted by noise, then when interrupted by silence (picket fence effect)

  • Miller and Licklider (1950) recordings of sound sequences regularly interrupted, sounds perceived more natural when interrupted by silence, then when interrupted by noise (picket fence effect)

Explanation

Question 3 of 3

1

    (c) asked to transcribe strangely synthesised speech
    (d) were able to do so
