Prototype: A Keyword Spotting-Based Intelligent Audio SoC for IoT

In this demo, we present a compact intelligent audio system-on-chip (SoC) integrated with a keyword spotting accelerator, enabling ultra-low latency, low-power, and low-cost voice interaction in Internet of Things (IoT) devices. Through algorithm-hardware co-design, the system’s energy efficiency is maximized. We demonstrate the system’s capabilities through a live FPGA-based prototype, showcasing stable performance and real-time voice interaction for edge intelligence applications.
