Для повышения точности оценки в режиме реального времени предложено использовать аудиомодальность с целью детектирования отрезков речи повышенной эмоциональности. В качестве показателя уровня речевой эмоциональности использована интенсивность потока гласных звуков в речевом сигнале пользователя на входе информационной системы. Разработан метод измерений этого показателя по эмпирической вероятности появления гласных звуков в речевом сигнале пользователя. Представлен пример практической реализации метода в режиме мягкого реального времени. С использованием авторского программного обеспечения поставлен и проведён натурный эксперимент. Показаны достоинства предложенного метода – быстродействие и высокая чувствительность к изменениям уровня речевой эмоциональности пользователей. Полученные результаты предназначены для разработчиков современных информационных системс аудиовизуальным пользовательским интерфейсом. </p></abstract><trans-abstract xml:lang="en"><p>In this paper, we consider the audiovisual data processing and interaction of two modalities for user’s emotional state prediction in dialogue information systems. The audio modality is used for real-time detection of emotional speech segments. As an indicator of the level of speech emotionality, it is proposed to estimate the intensity of the fl ow of vowels in the user's speech signal at the input of the information system. A novel method for measuring this indicator is proposed by using the empirical probability of the appearance of vowels in the speech signal. An example of its practical implementation in soft real time is provided. Using the author's software, a full-scale experiment was set up and carried out. The advantages of our method in terms of its high speed and sensitivity to the level of users' speech emotionality are shown. The obtained results are intended for developers of modern information systems with an audiovisual user interface.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>акустические измерения</kwd><kwd>акустика речи</kwd><kwd>эмоциональная речь</kwd><kwd>речевой сигнал</kwd><kwd>проблема малых выборок</kwd><kwd>искусственный интеллект</kwd><kwd>биометрия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>acoustic measurements</kwd><kwd>speech acoustics</kwd><kwd>emotional speech</kwd><kwd>speech signal</kwd><kwd>small samples problem</kwd><kwd>artifi cial intelligence</kwd><kwd>biometrics</kwd></kwd-group><funding-group><funding-statement xml:lang="en">the work is supported by RSF (Russian Science Foundation) grant no. 20-71-10010.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Davis S.
