Abstract: The upgraded Voice Assistant built using Gemini is a compact and intelligent embedded device designed for smooth, voice- driven interaction. A Raspberry Pi acts as the main processor, managing speech recognition, AI communication, and audio playback. A USB microphone captures speech input, while an audio amplifier and mini speaker generate clear vocal responses. The Raspberry Pi interprets the user’s query, forwards it to the AI model, and outputs the response in both audio and text form. An ESP32 microcontroller receives the text and displays it on an LCD screen for visual feedback. Powered through standard USB sources, the system offers hands-free assistance capable of answering questions, controlling IoT devices, and enabling real-time AI interactions. With its combination of AI processing, enhanced audio output, and microcontroller-based display, the system fits applications in home automation, education, accessibility, and personal assistance.
