Предложен способ сегментации голосового сигнала на периоды основного тона, который используется при расчете параметров джиттер и шиммер. Выполнено сравнение двух систем детектирования речевых нарушений при БАС, в одной из которых исходными данными являлись параметры голоса, полученные предлагаемым способом, а во второй - параметры, полученные в распространенной системе PRAAT. Результаты экспериментов показали, что применение прилагаемого способа анализа значительно улучшает (на 20 %) точность детектирования.</p></abstract><trans-abstract xml:lang="en"><p>A method of acoustic signal analysis with sustain vowel phonation for detection of amyotrophic lateral sclerosis (ALS) is considered. A method for segmentation of the voice signal into periods of the fundamental tone, which is used for evaluation of the jitter and shimmer parameters, is proposed. A comparison of two ALS detectors was performed. The first detector was trained using voice features extracted by the proposed method, while the second detector was trained using features obtained with PRAAT toolkit. The result showed a significant improvement (by 20 %) in the accuracy of detecting ALS disease using the proposed method.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>акустический анализ сигнала</kwd><kwd>джиттер</kwd><kwd>шиммер</kwd><kwd>боковой амиотрофический склероз</kwd></kwd-group><kwd-group xml:lang="en"><kwd>acoustic analysis</kwd><kwd>jitter</kwd><kwd>shimmer</kwd><kwd>amyotrophic lateral sclerosis</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">Завалишин И.А.
