Unit ASR

SKU:U194

Description

Unit ASR is an AI offline speech recognition unit, built with the CI-03T AI intelligent offline speech module. This unit features powerful speech recognition, voiceprint recognition, speech enhancement, and voice detection capabilities. It supports AEC (echo cancellation) to effectively eliminate echo and noise interference, improving speech recognition accuracy. It also supports mid-session speech interruption, allowing it to flexibly interrupt and quickly respond to new commands during recognition. The product comes preloaded with 42 English wake-up and response commands. It uses UART serial communication for data transfer and supports device wake-up via UART or keyword. The unit supports user configuration of wake-up recognition words in four languages: Chinese / English / Japanese / Korean. Users can modify the wake-up words by regenerating the firmware, and up to 300 command words are supported. Equipped with a microphone for clear audio capture and a built-in speaker for high-quality audio feedback, this product is used in AI assistants, smart homes, security monitoring, automotive systems, robots, smart hardware, and healthcare — making it an ideal choice for intelligent voice interaction.
