Dual-Channel DAC Output Voice Recognition Control Module Serial Port Wake-up Words HLK-V20 Wireless Intelligent Controll

Features: brand new and high quality Used for a large number of pure offline control scenarios and products. The audio signal is trained and learned through the neural network to improve the voice signal Recognition ability. Supports offline recognition of 150 local commands, freely customizable wake-up words, command words and response broadcast words, and has a wealth of peripheral interfaces. The module uses a 32bit RSIC architecture core, and adds a DSP instruction set specifically for signal processing and speech recognition, an FPU arithmetic unit that supports floating-point operations, and an FFT accelerator. Can be widely and quickly applied to smart homes, various smart small appliances, 86 boxes, toys, lamps, industrial, medical, Products that require voice control, such as the Internet of Things, automobiles, security and lighting.
