Self-initiated error-repairs in cluttering

Area of Science:

• Speech-Language Pathology
• Linguistics
• Psycholinguistics

Background:

• Cluttering is a speech disorder characterized by rapid and/or irregular speech rate, often accompanied by other fluency and speech production issues.
• Understanding how individuals who clutter (PWC) manage speech errors is crucial for developing targeted interventions.

Purpose of the Study:

• To analyze and compare the speech error-repair mechanisms of people with cluttering (PWC) to those of control speakers.
• To investigate potential differences in the timing and strategies employed during self-repair.

Main Methods:

• Analysis of spontaneous speech samples from 13 PWC and 13 age- and sex-matched control speakers.
• Measurement of error-to-cutoff time, duration of the editing phase, and error-to-repair time.
• Examination of repair strategies, including interruption points, delay proportions, and editing phases.

Main Results:

• No significant differences were found in the total duration of speech error repairs between PWC and control speakers.
• Potential differences in self-repair strategies were observed, suggesting distinct planning and execution approaches.
• Control speakers appeared to plan repairs in parallel with speech production, interrupting when a repair was ready.

Conclusions:

• While overall repair duration is similar, PWC may interrupt speech earlier to facilitate the planning of self-repairs.
• These findings suggest distinct cognitive-linguistic processes underlying speech error management in cluttering.
• Further research into PWC's self-repair strategies could inform more effective therapeutic approaches.
