Unit ASR

SKU:U194

Description

Unit ASR is an AI offline voice recognition unit equipped with the CI-03T AI intelligent offline voice module. This unit features powerful voice recognition, voiceprint recognition, voice enhancement, and voice detection capabilities. It supports AEC (Acoustic Echo Cancellation) to effectively eliminate echo and noise interference, improving voice recognition accuracy. It also supports mid-speech interruption, allowing flexible interruption during voice recognition and quick response to new commands. The product comes preloaded with 42 English wake words and feedback command words. The device uses UART serial communication for data transmission and can be woken up via UART or voice keywords. The unit supports user-defined wake words in multiple languages, and users can modify wake words by regenerating the firmware, supporting up to 300 command words. It is 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, vehicle systems, robotics and smart hardware, healthcare, and other fields, making it an ideal choice for intelligent voice interaction.
