Unit ASR is an AI offline voice recognition unit, built with the CI-03T AI intelligent offline voice module. The unit offers powerful capabilities such as speech recognition, voiceprint recognition, voice enhancement, and voice detection. It supports AEC (Acoustic Echo Cancellation), effectively removing echoes and noise interference, thereby enhancing voice recognition accuracy. It also supports mid-conversation voice interruption, allowing flexible interruption during voice recognition and quick response to new commands. The product comes pre-configured with 42 English wake-up words and feedback command words. It uses UART serial communication for data transmission and supports awakening the device via UART or voice keywords. The unit also supports user-customizable multi-language wake-up recognition words and can recognize up to 300 command words. Equipped with a microphone for clear audio capture and a built-in speaker for high-quality audio feedback, this product is widely used in AI assistants, smart homes, security monitoring, automotive systems, robotics, smart hardware, and healthcare. It is an ideal choice for implementing intelligent voice interaction.
