Polyglot interpreters are more resistant to speech disruption from delayed auditory feedback (DAF). Unlike medical students, interpreters maintained verbal fluency across various DAF conditions, highlighting their unique cognitive adaptations.

Area of Science:

  • Cognitive Science
  • Speech and Hearing Science
  • Linguistics

Background:

  • Delayed auditory feedback (DAF) is known to disrupt speech production.
  • The impact of DAF on individuals with high levels of multilingual proficiency is less understood.
  • Investigating the resilience of verbal fluency under DAF can reveal insights into cognitive control mechanisms.

Purpose of the Study:

  • To compare the effects of DAF on verbal fluency in polyglot interpreters and a control group.
  • To determine if simultaneous interpreters exhibit resistance to speech disruption caused by DAF.
  • To explore the relationship between multilingualism, attention, and speech stability.

Main Methods:

  • Participants included 12 simultaneous interpreters and 12 medical students (control group).

  • Verbal fluency was assessed under normal auditory feedback (NAF) and three DAF conditions (150, 200, 250 ms).
  • Speech disruption, including fluency reduction and errors, was measured across conditions and languages (L1 and L2 for interpreters).

    • Main Results:

    • The control group exhibited significant reductions in verbal fluency and increased errors under all DAF conditions.
    • Polyglot interpreters showed no significant speech disruption in their native (L1) or second language (L2) across all DAF intervals.
    • Interpreters demonstrated consistently high verbal fluency and resilience to DAF effects.

    Conclusions:

    • Simultaneous interpreters possess enhanced resistance to the disruptive effects of DAF on speech.
    • High verbal fluency and reduced self-monitoring of speech output contribute to this DAF resistance in interpreters.
    • These findings suggest specialized cognitive adaptations in polyglots that enhance speech stability.
