Abstract
This study introduces a smart retail system that integrates voice interaction, artificial intelligence, and robotic vending to connect digital recommendations with real-world product experiences. Designed to understand customer needs via voice input, it provides personalized suggestions and automatically dispenses product samples through a three-layer setup: IoT-based input, AI processing, and robotic output. Findings indicate that it enhances customer experience by enabling real-time interactions, simplifying product searches, and offering a more personalized shopping journey. Linking AI-driven recommendations with physical sampling also boosts purchase intent and promotional effectiveness through targeted suggestions. Overall, this research highlights the potential of combining voice AI, IoT, and robotics to develop a more interactive and efficient retail ecosystem with promising future applications.
