M5Stack Module ASR AI Intelligent Offline Voice Module
M5Stack Module ASR Artificial Intelligence (AI) Intelligent Offline Voice Module is based on a CI1302 chip and equipped with a microphone for clear audio acquisition and a built-in speaker for high-quality audio feedback. Module ASR supports mid-session voice interruption, enabling flexible interruption and quick responses to new commands during recognition. Integrated echo cancellation (AEC) effectively removes echoes and noise interference, improving recognition accuracy. This M5Stack AI offline voice module comes preloaded with 53 English wake-up and feedback command words and supports device activation via UART commands or voice keyword triggers.
Users can customize recognition words in Chinese, English, Japanese, and Korean by regenerating firmware, supporting up to 300 command words. The device communicates via a UART interface and allows switching between different UART pins through a DIP switch. This intelligence module is ideal for AI assistants, smart homes, security monitoring, automotive systems, robotics and smart hardware, and healthcare applications.
