Voice Recognition Module

I’m having some trouble with my voice recognition module, and I could really use your help. I’ve followed the instructions to copy the code and connect the hardware, but I’m not getting the response I expect.

 

Here’s what I’ve observed:

When I say “hello robot,” the blue light on the module turns on, but there’s no other response from the system.I’ve attached the code I’m using, along with a photo of the microchip and the voice activation module for reference. 

Could anyone help me troubleshoot this issue? What might I be doing wrong? Any advice or suggestions would be greatly appreciated!
