Product description
HLK-V20 is the latest high-performance pure offline speech recognition module for a 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, , 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 accelerator. The audio signal is trained and learned through the neural network to improve signal Recognition ability.
The solution supports offline recognition of 150 local commands, freely customizable words, words and response broadcast words, and has a wealth of peripheral interfaces.
Processing :32bit RISC core, running frequency 240M Support DSP instruction set and FPU floating point operation unit accelerator: supports up to 1024 points of complex /IFFT operations or 2048 points of real /IFFT operations
