Question 1

Question
The redundancy inherent in speech signal has what results?
Answer
  • (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

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

Question 3

Question
Sinewave speech, first investigated by Remez et al (1981) found that when presenting sinewave speech to listeners (a) they reported (b) and however listeners (c) reported (d)
Answer
  • (a) with no instructions (b) hearing beeps, and sci-fi music (c) asked to transcribe strangely synthesised speech (d) were able to do so
  • (a) with no instructions (b) were able to do so (c) asked to transcribe strangely synthesised speech (d) hearing beeps, and sci-fi music
