[Multiparameter analysis of dysphonia using the equipment Physiologia].
The purpose of the multiparametric analysis of the vocal phenomenon is to evidence the instability of the signal in amplitude and in frequency, together with the aerodynamic phenomena related to the glottic air leakage. Statistical analysis has made it possible to establish a correlation between the data of the apparatus, as from 9 variables, and the clinical classification. The main diagnostic categories are relatively close, evidencing the various biomechanical anomalies of the laryngeal vibrator. A certain number of issues remain to be addressed: the physiopathology of the vibrator, the choice of the phonetic sample, and the different methods of instrumental analysis.
