“…Today, 90% of occupations require information being exchanged using voice and articulated speech. Mastering of appropriate voice emission techniques is therefore important not only for individuals for whom their voice is the natural tool of their trade, for example teachers, actors, or singers, but also for individuals of other professions [1][2][3][4].…”

Introduction:The aim of the dissertation was to evaluate the parameters of acoustic and function analysis of the voice in patients with functional and organic dysphonia by using the DiagnoScope "Specjalista" computer program. Material and methods:The study was performed in 131 people aged 21-82 years (the mean age was 48,34 years), including 75 women, at the age of 21-75 years and 56 men at the age of 22-82 years, all treated in the Clinic of Otolaryngology, Laryngological Oncology, Audiology and Phoniatrics of the Military Medical Academy Memorial University Hospital -Central Veterans' Hospital. The study participants were divided into 3 groups: I -45 patients aged 22-82 years with functional dysphonia (hyperfunctional type dysphonia), II -45 patients aged 28-80 years with chronic hypertrophic laryngitis (polyp of the vocal fold, hypertrophy of the vocal fold, Reinke-type edema-hypertrophic changes in the vocal folds), III -41 individuals, including students of the Faculty of Military Medicine of the Medical University of Łódź, at the age of 21-70 years, without disease symptoms within the vocal organ. The following examinations were performed: a laryngological subject and object examination, a videolaryngoscopic and stroboscopic examination of the larynx (including the GRBAS scale), and a videolaryngostroboscopic-phoniatric examination, encompassing the following parameters: regularity of vibrations of the vocal folds, amplitude of vibrations, marginal shift, glottis closure, voice range, the way of creating the voice, voice reposition, time of phonation) and an acoustic and voice performance diagnostic analysis by the means of the DiagnoScope "Specjalista" program. results:The results obtained suggest that the differentiation of pathological voices from normal voices is statistically significant for parameters such as: Jitter, RAP, PPQ, AFO, SimpleQ, Shimmer, APQ, Q, APQ, HPQh, RHPQ, RHPQh, R2H, U2H, U2Hl, U2Hh, NHR, Yg. In the function analysis, statistically significant differences were found in all parameters. conclusions:The videolaryngostroboscopic examination, voice rating scales, and the objective analysis of the voice provide an appropriate set of tests that determine the nature of voice disorders. The acoustic and function analysis of the voice enables an early diagnosis of dysphonia, both functional and organic. The acoustic and function analysis is an objective method of assessment of the voice disorders which renders it possible to use it in judicature.
