HLK-V20 Speech Recognition Module Human Speech Voice Contr

Detailed Information About The Product:

Name：HLK-V20 Speech Recognition Module Human Speech Voice Control Module Development Board Custom Voice Control Switch Module
HLK-V20 is the latest high-performance pure offline speech recognition module for 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, Products that require voice control, such as the Internet of Things, automobiles, security and lighting.
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.
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, can freely customize wake-up words, command words and response broadcast words, and has a wealth of peripheral interfaces. Add a relay to the bottom plate to control high-power electrical appliances.
