Abstract	Voice-based human–robot interaction has emerged as a significant research domain for enabling natural, intuitive, and real-time communication between humans and intelligent robotic systems. Conventional humanoid robots have predominantly relied on predefined commands, keyword-based matching, or external application interfaces, which is limit conversational flexibility and reduce interaction intelligence. This paper presents the design, implementation, and evaluation of a voice- driven query to recognition and response system using the RoboMonk Mini humanoid robot. The proposed system employs an onboard microphone to capture real-time user speech, which is processed using speech recognition and artificial intelligence-based language understanding techniques. Recognized speech is converted into textual queries and interpreted using an AI language model capable of generating context-aware and meaningful responses. The generated response is delivered through the text-to-speech module, while synchronized humanoid gestures are executed using intelligent bus servo motors to enhance the interaction of naturalness. The system operates on an embedded Raspberry Pi processing platform, enabling autonomous and real-time conversational interaction without the dependency on external control interfaces. Experimental results to demonstrate the reliability of speech recognition performance, accurate AI-based response generation, smooth gesture synchronization, and improved user engagement. The proposed architecture is modular and scalable, supporting future enhancements such as multilingual interaction, emotion-based response adaptation, and autonomous mobility integration.
