Listener confusion patterns for speech sounds vary with the number of choices. Error patterns in confusion matrices depend on the specific consonant types and available response alternatives, impacting speech perception research.

Area of Science:

  • Speech perception research
  • Auditory psychophysics
  • Phonetics and phonology

Background:

  • Confusion matrices are crucial for understanding speech sound discrimination.
  • Previous research has explored speech sound confusions, but the impact of varying response set sizes needs further investigation.
  • Understanding error patterns is vital for developing effective speech processing technologies and diagnostic tools.

Purpose of the Study:

  • To investigate the invariance of error patterns in confusion matrices across different dimensions.
  • To determine how the size of the closed-set response alternatives affects consonant confusions.
  • To analyze the influence of consonant type (stops, fricatives) and voicing on error patterns.

Main Methods:

  • Presented digitized syllable tokens (consonant-/a/) from 14 consonants to normal-hearing young adults.

  • Utilized a closed-set format with varying numbers of response alternatives.
  • Recorded listener responses and analyzed error patterns in confusion matrices at three intensity levels.

    • Main Results:

    • Error patterns for voiceless stops and voiced fricatives were significantly influenced by the set of alternatives.
    • Voiceless fricatives and voiced stops showed no significant effect from the number of response alternatives.
    • Speaker and individual listener differences were observed, suggesting variability in confusion data.

    Conclusions:

    • Speech sound confusion patterns are not entirely invariant and depend on the specific phonetic features and the size of the response set.
    • Findings suggest caution when generalizing confusion data from small closed-set experiments to larger or different sets.
    • Listener and speaker variability necessitate consideration in auditory research and applications.
