This paper presents a comparative analysis of voice-controlled bots designed for managing laptop operating system services. The study examines key functionalities, including voice-based system control, file and folder management, speech-to-text writing, and voice-driven email interaction. The research analyzes technical architectures based on speech recognition, natural language processing, and OS automation mechanisms. Special attention is given to usability and accessibility aspects, particularly for users requiring hands-free interaction. The findings highlight the advantages and current limitations of voice-controlled assistants related to recognition accuracy, data security, and reliability of command execution. Overall, the study demonstrates the potential of voice-driven OS management systems to enhance accessibility and productivity in everyday computing environments.
