The ASR Unit is an AI-based offline voice recognition module that uses the CI-03T intelligent voice chip. It provides several advanced functions including speech recognition, voiceprint recognition, voice enhancement, and voice detection.
It features Acoustic Echo Cancellation (AEC), which helps reduce echo and noise interference. This improves the accuracy of voice recognition, especially in noisy environments. The unit also allows mid-conversation interruption, so it can respond quickly to new voice commands while already processing another.
The module comes with 42 pre-configured English wake-up and feedback words. It communicates using UART serial transmission and can be activated either by UART commands or voice keywords. Users can customise wake-up words in multiple languages and define up to 300 voice commands.
The unit includes a built-in microphone for clear voice input and a speaker for audio feedback. It’s suitable for use in AI assistants, smart home systems, security monitoring, in-vehicle controls, robotics, smart devices, and healthcare products.
This unit is a practical solution for adding intelligent voice interaction to a wide range of applications.
