HLK-V20

HLK-V20 is a high-performance pure offline voice recognition module newly launched by Hi-link Electronics according to a large number of pure offline control scenarios and products.

It can be widely and quickly applied to smart homes, various smart small appliances, 86 boxes, toys, lamps, Industrial, medical,Internet of Things, automotive, security and lighting products that require voice control.

The module uses a 32bit RSIC architecture core, and adds a DSP instruction set specifically for signal processing and speech
recognition, an FPU operation unit that supports floating point operations, and an FFT accelerator. The audio signal is trained
and learned through the neural network to improve the voice signal Recognition ability.

The solution supports offline recognition of 150 local commands, free configuration of wake-up words, command words, and broadcast reply words through the background, supports lightweight RTOS systems, rich peripheral interfaces, and simple and friendly customized tools.
