Обновление происходит по речевым сигналам зарегистрированных пользователей с запросами на их идентификацию и онлайн-обслуживание, при этом используется масштабно-инвариантный показатель качества голосовых образцов. Установлено, что применение масштабно инвариантного показателя обеспечивает необходимый уровень значимости решений, принимаемых условным наблюдателем. С применением авторского программного обеспечения поставлен и проведён натурный эксперимент, дано практическое обоснование эффективности предложенного способа. Полученные результаты будут полезны при разработке новых и модернизации существующих систем и технологий автоматизированного контроля качества и обновления биометрических персональных данных.</p></abstract><trans-abstract xml:lang="en"><p>The problem of “aging” of personal biometric data over time is considered. A method is proposed to overcome it by automatically updating the personal biometric data by using the speech signals of registered users obtained during latest requests for their identification and online service. The proposed method uses a scale-invariant indicator of the voice template quality. As a consequence, it is characterized by guaranteed reliability of the decisions made in the conditions of a wide speech signal dynamic range. It is shown that a guaranteed level of significance of decisions made by an observer is provided. The proposed method is implemented in a special software, which was used to experimentally estimate its effectiveness with real speech data. The obtained results are intended for use in the development of new and modernization of existing software and technologies for the personal biometric data automated quality control and updating.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>акустика речи</kwd><kwd>акустические измерения</kwd><kwd>речевой сигнал</kwd><kwd>биометрия</kwd><kwd>биометрическая система</kwd><kwd>биометрические персональные данные</kwd></kwd-group><kwd-group xml:lang="en"><kwd>speech acoustics</kwd><kwd>acoustic measurements</kwd><kwd>speech signal</kwd><kwd>biometrics</kwd><kwd>biometric system</kwd><kwd>personal biometric data</kwd><kwd>voice template</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">исследование выполнено при финансовой поддержке Российского научного фонда (проект № 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">Chawla S.
