We investigated how conditions that are known to be fluencyenhancing for individuals with persistent developmental stuttering (PDS) affect the speech of individuals with acquired neurogenic stuttering (ANS). Based on others’ claims that the overt speech dysfluencies of PDS and ANS are difficult to distinguish, as well as the derived hypothesis that similar neural mechanismsdor even similar neural deficitsdmay underlie both disorders, the purpose of the present work was to examine whether speakers with ANS experience the same improvements in speech fluency as do speakers with PDS during (a) repeated readings of the same material, (b) choral readings with a second speaker, and (c) readings with delayed or frequency-altered auditory feedback. Two individuals with ANS read passages out loud in each of these conditions. Results differed from those typically reported for individuals with PDS and, instead, showed (a) only a small amount of adaptation during repeated readings, (b) a small improvement for choral reading that never reached nearly fluent speech, and (c) an increase, rather than decrease, in dysfluency in the conditions with altered auditory feedback.
