FIELD: medicine.SUBSTANCE: invention relates to medicine, particularly to otorhinolaryngology. Video endoscopy of the larynx is performed using a flexible video endoscope, the laryngeal state is assessed during the functional tests (FB). During the video endoscopy and the FB, voice audio recording and video endostroboscopy of the larynx are also performed, and computer voice analysis (CVA) is carried out simultaneously with assessing the laryngeal state, and FB conduct, suggesting vocalist to sing in usual voice manner vowels "e", spaced from each other in frequency per one, namely arpeggio, starting from lowest in singing range of vocalist to highest first at "piano", then – "forte", wherein for soprano examination is carried out in range of c1–c3, for mezzo-soprano – a–a2, for contralto – f–a2, for tenor – c–c2, for baritone – A–f1, for bass – D–e1 with delay for each note of not less than four seconds, while providing video endoscopic analysis and CVA, then vocal technique peculiarities are compared with changes of objective acoustic indicators of voice function on the whole range, violations of vocal equipment affecting acoustic indicators are detected, after which features of voice guidance technique are identified, suggesting to perform a piece of the musical composition from their repertoire in the habitual manner of voice reading, duration of not less than one minute, with subsequent evaluation of video endoscopic picture of larynx in transition between thoracic and upper register, phonation with different dynamic characteristics, use of phonetic variety – vocalisation not only of vowels, but also consonants, in native and/or foreign language, and determining the effect of changes in the position of articulatory organs on the vocal position of the larynx, generating a differentiated approach based on the results of the analysis in the phonopedic correction of the detected disorders.EFFECT: method provides higher diagnostic effectiveness and phonopedic rehabi
