M5Stack M5GO battery base 2 for Core2

The ASR Voice Module from M5Stack is an AI-powered offline speech recognition module based on the powerful CI1302 chip. The module features a built-in microphone for clear audio recording and an integrated speaker for high-quality voice output. It supports speech interruption during recognition, allowing for flexible interaction and quick responses to new commands. The CI1302 chip integrates a high-performance neural network processor that supports deep learning-based noise suppression and echo cancellation. The offline functionality means that no internet connection is required for speech recognition, enhancing privacy and reliability. The module communicates via UART and can be activated through both serial commands and voice wake words. Users can configure custom wake words and commands in various languages through the Smart Pi platform. The module is ideal for AI assistants, smart home control, security systems, and robotics applications.
