Disfluencies, or speech interruptions, are not errors themselves but rather corrective actions for anticipated errors. This finding supports the self-repair hypothesis in speech production research.

Area of Science:

  • Psycholinguistics
  • Speech Production
  • Cognitive Science

Background:

  • Speech errors are deviations from a speech plan.
  • Disfluencies interrupt the execution of a speech plan.
  • Self-repairs correct speech errors.

Purpose of the Study:

  • To investigate the relationship between speech errors, disfluencies, and self-repairs.
  • To test two hypotheses: disfluencies as speech errors vs. disfluencies as self-repairs.
  • To determine the impact of accuracy focus on speech error patterns.

Main Methods:

  • Speakers recited stimulus sentences four times under time pressure.
  • Two conditions: high accuracy focus vs. low accuracy focus.
  • Comparison of speech error, disfluency, and self-repair rates between conditions.

Main Results:

  • Higher accuracy focus led to significantly lower speech error rates.
  • Disfluency and self-repair rates did not differ significantly between accuracy conditions.
  • This pattern supports the self-repair account of disfluencies.

Conclusions:

  • Disfluencies function as self-repairs, not as speech errors.
  • Prioritizing accuracy reduces speech errors but can decrease fluency.
  • Findings contribute to understanding speech production mechanisms and error correction.
