Gravity DF2301QF v1.0 Speaking in Chinese

Hello everyone,

I have just purchased Qty 10 of DF2301QF v1.0. I am new to this device and I have just powered up one with 5VDC. The problem is that it initiates in Chinese language and it does not accept wake up word “Hello Robot” or "Hi Robot". Can anyone suggest how do I proceed further?

Also want to know which pins are suitable for I2C and which pins are suitable for UART communication on an ESP32 WROOM Board?
