A study of individual differences in the fluency disruptions of speakers of two different accents, Standard Southern British English (SSBE) and York English is presented. Distributions of rates of occurrence per 100 syllables are examined for filled and silent pauses, repetitions, prolongations and (self-)interruptions, and subcategories of these. Patterns of occurrence of disfluency features show considerable between-speaker variation in both SSBE and York English. Similar ranges of speakers’ overall disfluency rates are exhibited by both accents, but cross-accent differences are present in the patterning of some disfluency feature categories. The results suggest that a detailed record of disfluency features is a useful additional tool in forensic speaker comparison.
