Welcome to Shenzhen Hi-link!
Please pay attation: the module only support ENGLISH , must customise by us, we will refer to your command and do customise.
HLK-V20 is a high-performancepure offline voice recognition modulenewly 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 requirevoice control.
The module uses a32bitRSIC architecture core, and adds aDSPinstruction set specifically for signal processing andspeech recognition, anFPUoperation 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 of150 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.

● 32bit RISC core, running frequency 240M
● Support DSP instruction set and FPU floating point operation unit
● FFT accelerator: supports up to 1024 points of complex FFT/IFFT operations or 2048 points of real FFT/IFFT operations
● Customized voice algorithm operator
Storage:
● Built-in high-speed SRAM
● Built-in 2MB FLASH
Audio input and output:
● Support 1 analog Mic input, SNR≥94db
● Support 4 digital Mic input

Custom voice:
● Customize the startup announcement
● Custom voice wake-up words
● Customize voice command words
● Custom TTS voice broadcast
● Support no wake-up words (no need to wake up, direct recognition of command words)
The module has rich system peripherals, including UART/I2C/SPI/PWM/I2S/DAC/GPIO/ DMic/AMic. The following figure shows the functional block diagram of the module system.
