EasyVR shield for voice recnognition is not working

My EASYVR SHIELD doesn't work.. I put it onto arduino mega and programmed with the easyvr commander. And for now is all ok. But then i generated the code and seems that arduino is not receiving easyvr. I'm trying to whink why. I tried all the bridge connections but seems to be not valid.
HELP ME PLEASE

#include "Arduino.h"
#if !defined(SERIAL_PORT_MONITOR)
  #error "Arduino version not supported. Please update your IDE to the latest version."
#endif

#if defined(__SAMD21G18A__)
  // Shield Jumper on HW (for Zero, use Programming Port)
  #define port SERIAL_PORT_HARDWARE
  #define pcSerial SERIAL_PORT_MONITOR
#elif defined(SERIAL_PORT_USBVIRTUAL)
  // Shield Jumper on HW (for Leonardo and Due, use Native Port)
  #define port SERIAL_PORT_HARDWARE
  #define pcSerial SERIAL_PORT_USBVIRTUAL
#else
  // Shield Jumper on SW (using pins 12/13 or 8/9 as RX/TX)
  #include "SoftwareSerial.h"
  SoftwareSerial port(12, 13);
  #define pcSerial SERIAL_PORT_MONITOR
#endif

#include "EasyVR.h"

EasyVR easyvr(port);

  S3_TEN = 10,
};


// use negative group for wordsets
int8_t group, idx;

void setup()

And the serial is on SW
