The author presents via a multimedia analysis (nasovideo, fibroscopic,
endoscopies, acoustic recordings, spectrographic analysis etc…) recordings made
along the two past years on severe stutterers and the
same subjects using speech modifications techniques as well as normally fluent
speakers. Each patient had been recorded (synchronized numeric video and
acoustic recordings) for at least two to four minutes. The data will be
described and compared. Further comments will be made about implications and
new perspectives for diagnosis, the role of the larynx during stuttering, and
the effectiveness of speech modification techniques.
