A case of word-final prolongations occurring in an adult male with neurofibromatosis type 1 is reported. Speech samples were collected in five different speech modalities (i.e. spontaneous speech, monologue, repetition, automatic series and reading) and subsequently analyzed in a semi-automatic manner using Praat software. Results on the frequency, nature and distribution of the word-final prolongations are presented. The possible pathogenesis of these word-final disfluencies and their relation to stuttering is discussed. EDUCATIONAL OBJECTIVES: The reader will be able to: (1) describe the characteristics of word-final prolongations as displayed by an adult male with neurofibromatosis type 1 and (2) discuss the possible pathogenesis of these word-final prolongations and their relation to stuttering.
