Pseudofluency in adults who stutter: the illusory outcome of therapy.

The majority of therapy programs for people who stutter are aimed at modifying the entire speech output by using techniques that reduce the overt signature events. Use of these techniques for extended time periods are thought to induce true fluency that is automatic, natural, and effortless. It is proposed that the present form of therapeutic intervention induces pseudofluency rather than true fluency. Pseudofluency is the speech posrtherapy of persons who stutter, free of the discrete signature events of stuttering, but replaced by cognitively mediated gestures that are embedded as continuous prolongation or masked stuttering events throughout the speech act. This may account for the high rate of relapse and the problems associated with the maintenance, stability, and naturalness of speech after stuttering therapy.
