Целью исследования является разработка интеллектуальной системы планирования, функционирующей локально на оборудовании пользователя без передачи данных в Интернет.</p></sec><sec><title>Методы</title><p>Методы. Рассматривается проблема обеспечения конфиденциальности и автономности цифровых ассистентов, зависящих от облачной инфраструктуры. Предложена клиент-серверная архитектура, в которой серверная часть реализована с использованием фреймворка FastAPI и базы данных SQLite, а клиентский интерфейс разработан на языке JavaScript. Визуализация расписания и редактирование записей осуществляются через веб-интерфейс.</p></sec><sec><title>Результаты</title><p>Результаты. Описан голосовой конвейер системы: для активации используется движок Porcupine, для транскрибации – модель Faster-Whisper с квантованием int8. Проведен сравнительный анализ технологического стека, обеспечивающего высокую точность распознавания речи. Разработан гибридный модуль понимания естественного языка. Реализована технология RAG, интегрирующая данные расписания в контекст генерации ответа. Для синтеза речи используется нейросеть Piper, выполнение которой через ONNX Runtime обеспечивает высокую скорость обработки. Разработан эвристический алгоритм жадного поиска для управления временными ресурсами.</p></sec><sec><title>Заключение</title><p>Заключение. Сделан вывод о применимости разработанной системы в корпоративном секторе, где критически важны защита информации и функционирование в условиях закрытого сетевого контура.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Objectives</title><p>Objectives. The aim of the research is to develop an intelligent scheduling system operating locally on the user's equipment without data transmission via Internet.</p></sec><sec><title>Methods</title><p>Methods. This paper examines the problem of ensuring the privacy and autonomy of digital assistants dependent on cloud infrastructure. A client-server architecture is proposed, in which the server component is implemented using the FastAPI framework and an SQLite database, and the client interface is written in JavaScript. Schedule visualization and entry editing are performed through the web interface.</p></sec><sec><title>Results</title><p>Results. The system's voice pipeline is described: the Porcupine engine is used for activation, and the Faster-Whisper model with int8 quantization is used for transcription. A comparative analysis of the technology stack, ensuring high speech recognition accuracy, is conducted. A hybrid natural language understanding module is developed. RAG technology is implemented, integrating schedule data into the response generation context. Speech synthesis is performed using the Piper neural network, whose execution through ONNX Runtime ensures high processing speed. A heuristic greedy search algorithm for managing time resources has been developed.</p></sec><sec><title>Conclusion</title><p>Conclusion. The developed system is considered applicable in the corporate sector, where information security and operation in closed network environments are critical.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>интеллектуальная система</kwd><kwd>голосовой ассистент</kwd><kwd>нейронные сети</kwd><kwd>планирование задач</kwd><kwd>распознавание речи</kwd><kwd>естественный язык</kwd><kwd>графическая оболочка</kwd></kwd-group><kwd-group xml:lang="en"><kwd>intelligent system</kwd><kwd>voice assistant</kwd><kwd>neural networks</kwd><kwd>task planning</kwd><kwd>speech recognition</kwd><kwd>natural language</kwd><kwd>graphical shell</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">Robust Speech Recognition via Large-Scale Weak Supervision / A.
