U194 ASR Unit

M5Stack U194 ASR Unit is an AI offline voice recognition unit built with the CI-03T AI intelligent offline voice module. This unit offers powerful capabilities such as speech recognition, voiceprint recognition, voice enhancement, and voice detection. The U194 ASR unit supports Acoustic Echo Cancellation (AEC) effectively removing echoes and noise interference, thereby enhancing voice recognition accuracy. This unit also supports mid-conversation voice interruption, allowing flexible interruption during voice recognition and quick response to new commands. The U194 ASR unit uses UART serial communication for data transmission and supports awakening the device via UART or voice keywords. This unit is equipped with a microphone for clear audio capture and a built-in speaker for high-quality audio feedback. Typical applications include AI assistants, smart homes, security monitoring, automotive systems, robotics and smart hardware, and healthcare.
