Ai-Thinker VC-02 Offline Speech Recognition Control Module
The VC-02-Kit is a development board for the Voice Recognition Module, sharing the same design as the VC-01-Kit. It features an integrated CH340C USB-to-serial chip for debugging and upgrading, with added functionality like wake-up light, cold, and cooling lamp control, along with status indicators for easy debugging and control. Developed by Shenzhen Ai-Thinker Technology Co., Ltd., the VC-02 is a cost-effective offline speech recognition module that uses the US516P6 voice chip from Unisound. This chip offers a deep integration of offline recognition algorithms, providing an ultra-low-cost speech recognition solution. It is ideal for smart homes, small household appliances, 86 boxes, toys, lamps, and more, enabling voice control. The US516P6 chip features a 32-bit RISC architecture, DSP instructions for signal processing, an FPU unit for floating-point operations, and an FFT accelerator. The VC-02 Voice Recognition Module supports 150 local offline commands and a lightweight RTOS system, making it easy to customize with a variety of peripheral interfaces.
