Сравнивались параметры голоса, определяемые клинической системой lingWaves, и параметры, получаемые в результате мел-частотного кепстрального анализа голоса. Для определения пригодности данных параметров при решении задачи выявления заболеваний гортани на их основе строился классификатор с использованием вероятностной модели – логистической регрессии. Для обучения классификатора была записана база голосов 60 человек, 30 из которых составляли контрольную группу, а другие 30 имели различные заболевания гортани (узелки голосовых складок, паралич гортани или функциональную дисфонию). Показано, что точность классификатора на основе мелчастотных кепстральных параметров (83,8 %) выше, чем точность классификатора на основе параметров, полученных в системе lingWaves (60,4 %).</p></abstract><trans-abstract xml:lang="en"><p>The comparative study of two types of voice signal representation for larynx pathology detection is presented. Parameters obtained in clinical system lingWaves compared to parameters obtained by mel-frequency cepstral analysis. The classifier based on the probabilistic model (logistic regression) was designed to determine the suitability of given parameters for the larynx pathology detection problem. To train the classifier, the base of voice samples of 60 persons was recorded, 30 of which constitute the control group, and the other 30 had various diseases of the larynx (nodules of the vocal folds, laryngeal paralysis, or functional dysphonia). The results show that the classifier based on mel-frequency cepstral parameters (83,8 %) higher than the classifier based on parameters obtained in lingWaves (60,4 %).</p></trans-abstract><kwd-group xml:lang="ru"><kwd>анализ голоса</kwd><kwd>акустические параметры голоса</kwd><kwd>кепстральный анализ</kwd><kwd>детектирование патологии в голосе</kwd><kwd>логистическая регрессия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>voice analysis</kwd><kwd>acoustic voice parameters</kwd><kwd>cepstral analysis</kwd><kwd>voice pathology detection</kwd><kwd>logistic regression</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Шиленкова, В.
