Disfluencies in cluttered speech

Area of Science:

• Speech-Language Pathology
• Linguistics
• Communication Sciences

Background:

• Cluttering is a speech disorder characterized by rapid or irregular speech rate, often accompanied by disfluencies.
• Understanding the specific nature of disfluencies in cluttering is crucial for differential diagnosis and effective intervention.
• Previous research has not fully elucidated the similarities and differences in disfluency patterns between cluttering and typical speech.

Purpose of the Study:

• To investigate the types and frequency of disfluencies in the conversational speech of individuals who clutter compared to typical speakers.
• To analyze disfluencies occurring as singletons and in clusters.
• To contribute to the understanding of cluttering, its relationship to stuttering, and its definition.

Main Methods:

• Comparative analysis of conversational speech samples.
• Identification and quantification of various disfluency types (e.g., revisions, word repetitions).
• Examination of disfluency occurrence in both single instances and clusters.

Main Results:

• Nearly all disfluency types occurred with indistinguishable frequency between individuals who clutter and typical speakers.
• Notable exceptions included revisions in clusters and word repetitions in clusters, which may differ.
• This study provides empirical documentation on the nature of disfluencies in cluttering.

Conclusions:

• The findings suggest significant overlap in disfluency patterns between cluttering and typical speech.
• This challenges some assumptions and refines our understanding of cluttering within the broader spectrum of fluency disorders.
• The results have implications for the Cluttering Spectrum Hypothesis and the definition of cluttering.
