Stuttering and Apraxia of Speech: the Efficacy of an Intervention Program

2010-07-15 17:00:00 | BioPortfolio


Subjects' utterances were submitted to acoustic analysis before and after the intervention program applied on prosodic basis.


The study has the aim of developing knowledge, methodology and technique in the prosody area, for its application on the speech therapy, with the assistance of a feedback system - with WinpitchPro (Philippe Martin). A database was constituted on the basis of a patterned corpus (EUROM1) by its translation, recording and editing on .wav format. Throughout model-sentences, an experimental intervention program initiates with the participation of 2 adults with stuttering problem and 2 with apraxia of speech. The efficacy of the therapeutic procedure is tested on the basis of the acoustical and the statistical analyses which have compared the first and the second speech samples taken before and after the twenty (20) therapy sessions held in a prosody approach only.

A disturbance in the normal fluency and time patterning of speech that is inappropriate for the individual's age. This disturbance is characterized by frequent repetitions or prolongations of sounds or syllables. Various other types of speech dysfluencies may also be involved including interjections, broken words, audible or silent blocking, circumlocutions, words produced with an excess of physical tension, and monosyllabic whole word repetitions. Stuttering may occur as a developmental condition in childhood or as an acquired disorder which may be associated with BRAIN INFARCTIONS and other BRAIN DISEASES. (From DSM-IV, 1994)

A method of comparing the cost of a program with its expected benefits in dollars (or other currency). The benefit-to-cost ratio is a measure of total return expected per unit of money spent.
