The hyperspace effect in vowel perception is influenced by consonant context and talker familiarity. However, listeners

Area of Science:

  • Psycholinguistics
  • Auditory Perception
  • Phonetics

Background:

  • The hyperspace effect suggests adaptive dispersion is an active perceptual process in vowel perception.
  • Previous research on adaptive dispersion used isolated vowels in unfamiliar voices, potentially limiting findings.

Purpose of the Study:

  • To investigate the influence of consonant context and talker familiarity on the hyperspace effect.
  • To determine if adaptive dispersion is modulated by contextual and familiarity factors.

Main Methods:

  • Experimentation involving vowel stimuli presented with varying consonant contexts.
  • Utilizing familiar and unfamiliar talkers to assess familiarity effects.
  • Analysis of listeners' preferred perceptual spaces in relation to production vowel spaces.

Related Experiment Videos

Main Results:

  • Both consonant context and talker familiarity were found to modulate the hyperspace effect.
  • The observed reductions in the hyperspace effect due to context and familiarity were minimal.
  • Listeners' perceptual spaces remained hyperarticulated compared to the actual production vowel space.

Conclusions:

  • Adaptive dispersion in vowel perception is influenced by linguistic context and talker familiarity.
  • Despite modulation, listeners' perceptual systems maintain a degree of hyperarticulation.
  • Findings suggest active perceptual processes shape vowel space representation.
