At the same time, patients with hearing impairment show changes in the speech production compared to those who hear normally, which are caused by a deterioration in the feedback of auditory communication. To what extent the auditory control that is impaired in sensorineural hearing loss (SNHL) can be compensated for with hearing aids remains a little-studied question. A study of the effect of restored auditory control on articulatory motor skills with adequate hearing aids has been conducted. A comparison of the durations of stressed vowels and individual words in speech uttered with and without a hearing aid was performed in 12 speakers (6 of them men) with moderately severe chronic SNHL. For stressed vowels [a], [i], [u], which make up the vertices of the vowel triangle for the Russian language, in all positions – the beginning, middle and end of the word, a significant decrease in their duration was revealed when wearing hearing aids compared to speaking without them. In most cases, the duration of stressed vowels varied by about 10%, and the duration of individual words containing such vowels by 5%. A decrease in the duration of stressed vowels and individual words can be an objective indicator for evaluating the effectiveness of auditory prosthetics to restore auditory feedback and normalize speech motor skills.</p></abstract><trans-abstract xml:lang="ru"><p>У постлингвально оглохших пациентов, в отличие от потерявших слух в раннем возрасте, сохраняется сформированный ранее контроль на основе прямой связи слуха и речи. Вместе с тем при нарушении слуха у пациентов выявляются изменения в процессе речепродукции по сравнению с нормально слышащими, которые обусловлены ухудшением обратной слуховой связи. Насколько нарушенные при тугоухости механизмы слухового контроля могут быть скомпенсированы при слухопротезировании, остается малоизученным вопросом. Проведено исследование влияния восстановленного слухового контроля на артикуляционную моторику при адекватном слухопротезировании. Выполнено сравнение длительностей ударных гласных и отдельных слов в речи, произнесенной в слуховом аппарате и без него, у 12 дикторов (из них 6 мужчин) с хронической сенсоневральной тугоухостью (СНТ) III степени. Для ударных гласных [a], [i], [u], составляющих вершины треугольника гласных для русского языка, во всех положениях – начале, середине и конце слова, выявили достоверное снижение их длительности при надетых слуховых аппаратах по сравнению с говорением без них. В большинстве случаев длительность ударных гласных изменялась примерно на 10%, а длительность отдельных слов, содержащих такие гласные, – на 5%. Снижение длительности ударных гласных звуков и отдельных слов может являться объективным показателем для оценки эффективности слухопротезирования по восстановлению слухоречевой обратной связи и нормализации моторики речи.</p></trans-abstract><kwd-group xml:lang="en"><kwd>audiomotor control</kwd><kwd>feedback control</kwd><kwd>speech</kwd><kwd>voice</kwd><kwd>sensorineural hearing loss</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>слухоречевой контроль</kwd><kwd>характеристики речи</kwd><kwd>слухопротезирование</kwd><kwd>сенсоневральная тугоухость</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">Правительство Российской Федерации</institution></institution-wrap><institution-wrap><institution xml:lang="en">Government of the Russian Federation</institution></institution-wrap></funding-source><award-id>075-00263-25-00</award-id></award-group></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Batalin S.V.
