Description

Module ASR is an AI intelligent offline voice module designed based on the CI1302 chip. Equipped with a microphone for clear audio acquisition and a built-in speaker for high-quality audio feedback. It supports mid-session voice interruption, allowing for flexible interruption and quick response to new commands during recognition. Integrated AEC (Echo Cancellation) effectively removes echoes and noise interference, improving recognition accuracy. The product comes preloaded with 53 English wake-up and feedback command words and supports activating the device through 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. It is ideal for AI assistants, smart homes, security monitoring, automotive systems, robotics & smart hardware, and healthcare applications a perfect choice for intelligent voice interaction.
