Great advances in this direction have been made using ECoG and stereo-EEG. At the same time, there are few works on this topic on the analysis of data obtained by non-invasive methods of recording brain activity. Our approach is based on the evaluation of connections in the space of sensors with the identification of a pattern of MEG connectivity specific for a given segment of speech. We tested our method on 7 subjects. In all cases, our processing pipeline was quite reliable and worked either without recognition errors or with a small number of errors. After “training”, the algorithm is able to recognise a fragment of oral speech with a single presentation. For recognition, we used segments of the MEG recording 50–1200 ms from the beginning of the sound of the word. For high-quality recognition, a segment of at least 600 ms was required. Intervals longer than 1200 ms worsened the recognition quality. Bandpass filtering of the MEG showed that the quality of recognition is equally effective in the entire frequency range. Some decrease in the level of recognition is observed only in the range of 9–14 Hz.</p></abstract><trans-abstract xml:lang="ru"><p id="idm45257552014016">Распознавание устной речи по данным ЭЭГ и МЭГ является первым шагом разработки систем МКИ и ИИ для дальнейшего использования их при декодировании воображаемой речи. Большие достижения в этом направлении были сделаны с использованием ЭКоГ и стерео-ЭЭГ. В то же время существует мало работ на эту тему по анализу данных, полученных неинвазивными методами регистрации активности мозга. Наш подход основан на оценке связей в пространстве сенсоров с выделением специфического для данного отрезка речи паттерна связанности МЭГ. Мы проверили свой метод на 7 испытуемых. Во всех случаях наш конвейер обработки был достаточно надежен и работал либо без ошибок распознавания, либо с небольшим количеством ошибок. После “обучения” алгоритм способен распознавать фрагмент устной речи при единственном предъявлении. Для распознавания мы использовали отрезки записи МЭГ 50–1200 мс от начала звучания слова. Для качественного распознавания требовался отрезок не менее 600 мс. Интервалы больше 1200 мс ухудшали качество распознавания. Полосовая фильтрация МЭГ показала, что качество распознавания одинаково эффективно во всем диапазоне частот. Некоторое снижение уровня распознавания наблюдается только в диапазоне 9–14 Гц.</p></trans-abstract><kwd-group xml:lang="en"><kwd>speech decoding</kwd><kwd>sensor space connectivity</kwd><kwd>MEG</kwd><kwd>EEG</kwd><kwd>BCI</kwd><kwd>AI</kwd><kwd>theta-rhythm</kwd><kwd>alpha-rhythm</kwd><kwd>gamma-rhythm</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>декодирование речи</kwd><kwd>связанность в пространстве сенсоров</kwd><kwd>МЭГ</kwd><kwd>ЭЭГ</kwd><kwd>МКИ</kwd><kwd>ИИ</kwd><kwd>тета-ритм</kwd><kwd>альфа-ритм</kwd><kwd>гамма-ритм</kwd></kwd-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Anumanchipalli G.K., Chartier J., Chang E.F.
