Voice recognition module with ESP32.
FPGA Spartan 6
The module is equipped withFPGA Spartan 6, which was used for fast audio processing and advanced voice algorithms. With the help of it, we managed to obtain such properties as:beam forming, AEC, reverberation removal and noise reduction. The performance of the module can be improved by adjusting it yourself, or by downloading manufacturer's updates.
