Abstract

The Multi Dimensional Voice Program (MDVP) is a powerful software tool for quantitative acoustic assessment of voice quality; it is capable of calculating 33 parameters and provides flexible routines for graphical representation of the results. Also a user-upgradeable voice database allows automatic comparison of the current results with different nosological groups. In our experience fundamental frequency (Fo), Jitter percent, Shimmer, noise to harmonics ratio (NHR), voice turbulence index (VTI), soft phonation index (SPI), degree of voiceless (DUV), degree of voice breaks (DVB) and peak amplitude variation (vAm) are the parameters which give the most objective information about the presence of vocal modification. A multiple regression analysis of these nine acoustic measures may provide a quick and relatively sensitive method that may be clinically useful in measuring change of vocal quality and articulation. These data provide a more complete analysis in conjunction with other tests: the mirror-fogging test from Glatzel and the Gutzmann test (for testing nasality); the voice handicap index (a validated questionnaire measuring psychosocial handicapping effects of voice disorders); Van Borsel's study (to evaluate articulation). We have applied this protocol in the analysis of speech and voice before and one month after different surgical techniques (tonsillectomy, adenotonsillectomy, uvulopalatoplasty, septoplasty, microlaryngoscopy, etc). Our protocol of voice and speech analysis provide objective, documentable and measurable data of vocal function, and these measurements are clinically helpful for the comparison of the patients' voice with those of healthy speakers. These measures maybe very useful to evaluate the patient affected by pathology and to provide a more secure diagnosis. For these reasons, otorhinolaryngologist should evaluate patients also using the MDVP, in conjunction with other test, at the beginning of their "diagnostic challenge". © 2010 Nova Science Publishers, Inc.
