I found it sir. Thank you for the info.

Here are the codes:

#include <SoftwareSerial.h>
#include "VoiceRecognitionV3.h"

/**        
  Connection
  Arduino    VoiceRecognitionModule
   2   ------->     TX
   3   ------->     RX
*/
VR myVR(2,3);    // 2:RX 3:TX, you can choose your favourite pins.

uint8_t records[7]; // save record
uint8_t buf[64];

int const ledTime = 13

#define timeRecord (0)

void setup() {
  /** initialize */
  myVR.begin(9600);
  
  Serial.begin(115200);
  Serial.println("Elechouse Voice Recognition V3 Module\r\nControl LED sample");
  
  pinMode(ledTime, OUTPUT); digitalWrite(ledTime, HIGH);
    
  if(myVR.clear() == 0){
    Serial.println("Recognizer cleared.");
  }else{
    Serial.println("Not find VoiceRecognitionModule.");
    Serial.println("Please check connection and restart Arduino.");
    while(1);
  }
  if(myVR.load((uint8_t)timeRecord) >= 0){
    Serial.println("timeRecord loaded");
  }

}

void loop() {
  int ret;
  ret = myVR.recognize(buf, 50);
  if(ret>0){
    switch(buf[1]){
      case timeRecord:
        digitalWrite(led, LOW);
        delay(1000);
        digitalWrite(led, HIGH);
        break;
      default:
        Serial.println("Record function undefined");
        break;
    }
    /** voice recognized */
    printVR(buf);
  }
}
