HLK-V20 is the latest high-performance pure offline speech recognition module for a large number of pure offline control scenarios and products. 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. Featured By RoboticsBD.

How to Use:

The demo firmware supports voice wake‑up words: Xiaoke Xiaoke, Xiaoling Xiaoling, Hello Lamp, Xiaohai Xiaohai.

  1. Use the USB data cable to supply power to the test board, and connect external speakers and microphones.
  2. After the module wakes up, use the order word "turn on the air conditioner", the bottom D4 will light up, corresponding to the B7 pin on the module, use the order word "turn off the air conditioner", and the D4 light will go out. 
  3. Use the order word "turn on the light", the bottom plate D3 will light up, corresponding to the B6 pin on the module, use the order word "turn off the light", and the D3 light will go out. 
  4. Use the order word "Turn on the switch", the bottom plate D2 will light up, corresponding to the B2 pin on the module, use the order word "Turn off the switch", and the D2 light will go out. 
  5. Only the above 3 pins are active in the factory demo firmware, and none of the other pins are active.

More Documentation:

This module also has a relay. Customers can connect pin B2 to RELAY (relay control pin), or B6 to RELAY, or B7 to RELAY through the short-circuit cap.

In the picture, the shorting cap is connected to B6 and RELAY, because the command word "turn on the light" can directly control the switch of the relay without the wake-up word "Xiaoling Xiaoling". If the short cap jumps on B2 and B7, you need to wake up first and then control.

It should be noted that the LED lights D2, D3, and D4 are 3.3v and 5v respectively. The voltage difference will cause the light to be slightly bright, and it can be used normally without affecting the function.

Package Includes:

1 x HLK-V20 Speech Recognition Module Human Speech Voice Control Module.
